Analyst Perspective

“Over the next ten years, I expect new high-bypass engines to leave less nacelle surface for acoustic treatment, due to which attenuation per kilogram will become the main buying measure. Engine and nacelle programs, at 44% of demand in 2026, will stay the largest source of orders as the LEAP ramp continues, and suppliers in Poland and Mexico, growing at 5.9% and 5.6% CAGR through 2036, will take a larger part of new panel work as production moves closer to engine and aerostructure lines.”

Why Do Aircraft Nacelle Liners Lead the Acoustic Liners Market by Liner Type?

Based on liner type, aircraft nacelle liners will account for 36% of market share in 2026.

Aircraft nacelle liners are projected to capture the largest share of the liner type category, at 36% of demand in 2026. Demand is driven by engine programs ordering a complete liner set with every new engine, at a higher value per installation than any other buyer group. Demand for duct, panel, honeycomb and perforated composite liners will be slower, as HVAC, rail and industrial buyers order only when a building or plant project starts.

• Aircraft nacelle liners are projected to account for 36% of demand by liner type in 2026. Demand is driven by every new engine shipping with a full liner set.
• Airbus inaugurated a new A320 Family final assembly line in Toulouse in June 2026, adding nacelle demand on the highest-volume single-aisle program [3].

Why Does Nomex Honeycomb Lead the Acoustic Liners Market by Material?

In 2026, Nomex honeycomb will account for 31% of market share by material.

Nomex honeycomb is leading the material category with 31% of demand in 2026, as aircraft and nacelle makers seldom change an approved material once an engine program is running. Adoption of carbon composite, glass fiber, aluminum honeycomb and foam laminates will be slower, since rail, marine and industrial buyers choose these mainly on price and in small project volumes.

• Nomex honeycomb is estimated to hold 31% of demand by material in 2026, owing to approved use on running engine programs.
• In June 2025, Hexcel signed a five-year agreement with Kongsberg covering HexWeb engineered honeycombs and HexPly prepregs [4].

Why Do Aircraft Engines and Nacelles Lead the Acoustic Liners Market by End Use?

By end use, aircraft engines and nacelles will account for 44% of market share in 2026.

Aircraft engines and nacelles will dominate end use with 44% of demand in 2026. Demand is driven by rising engine deliveries, which create the largest and most regular stream of liner orders. Sales of liners for HVAC ducts and industrial silencers will grow more slowly, as these orders follow construction starts and plant upgrades. Rail and marine buyers order mainly at fleet renewal, which comes years apart.

• Aircraft engines and nacelles are projected to account for 44% of demand by end use in 2026. Sales are driven by rising engine deliveries, as each delivery adds a new liner order.
• JAXA reported in May 2025 that ultra-high-bypass engines leave a smaller sound-absorbing liner area than conventional engines [5].

Why Do Aircraft and Nacelle OEMs Lead the Acoustic Liners Market by Sales Channel?

Based on sales channel, aircraft and nacelle OEMs will account for 42% of market share in 2026.

Aircraft and nacelle OEMs account for the largest share of the sales channel category, placing 42% of liner orders in 2026. Adoption of the OEM channel is due to buyers preferring one source for liners across the full production life of each engine. Demand through system suppliers, MRO and retrofit shops and industrial distributors will be slower, as these buyers order replacement panels only after damage or wear.

• Aircraft and nacelle OEMs are expected to place 42% of liner orders in 2026, as program owners keep liner sourcing for the life of each engine.
• Boeing completed the acquisition of Spirit AeroSystems in December 2025, bringing Spirit's commercial and aftermarket operations into Boeing [6].

Why Does Noise Attenuation Lead the Acoustic Liners Market by Application?

In 2026, noise attenuation will account for 39% of market share by application.

Noise attenuation is expected to hold the top position in the application category with 39% of demand in 2026, as airports, building codes and workplace rules set noise limits buyers have to meet. Demand for flow duct lining, fan and engine noise control and cabin comfort will be slower, since buyers fund these only on new aircraft programs or premium building projects.

• Noise attenuation is projected to account for 39% of demand by application in 2026. Adoption is driven by tighter noise limits at airports and in buildings.
• In June 2025, the Dutch regulator ACM allowed Schiphol to charge more for the noisiest aircraft categories and less for quieter ones, to encourage airlines to fly quieter aircraft [7].

What are the Drivers, Restraints, and Opportunities in the Acoustic Liners Market?

Key drivers of the acoustic liners market include rising engine output and noise certification, according to FMI. Key challenges in the acoustic liners market include long qualification cycles, and sales potential is expected to emerge from compact liners for high-bypass engines through 2036.

• Driver: Among other drivers, higher engine deliveries will lead to massive sales of acoustic liners, as each new engine needs a certified liner set for the inlet, fan duct and thrust reverser.
• Restraint: Key challenges faced by manufacturers include long qualification cycles, as each new liner has to prove attenuation without extra weight, drag, pressure loss or repair problems.
• Opportunity: Sales potential is expected to emerge from compact liners for high-bypass engines, as new engines leave less liner area and need more attenuation from each panel.

Demand for replacement liner panels is increasing as more engines enter service each year. Airlines send damaged inlet and fan duct panels to approved repair shops, and each repair needs certified liner data from the original program. Core material supply is also expanding, as the honeycomb core materials market is projected to grow from USD 3.5 Billion in 2025 to USD 7.6 Billion by 2035 at 8% CAGR. Repair shops holding approved liner data are expected to receive a larger share of replacement panel orders through 2036.

Weight and qualification form the main challenges in the market, as an extra noise panel adds mass and fuel burn to an aircraft. Nacelle liners also face airflow, moisture and erosion in service. Buyers ask for production parts and repair methods that hold the approved acoustic performance over the life of the engine. Core supply is widening, as the aramid honeycomb core material market is projected at 12.6% CAGR through 2035 and the honeycomb aluminum foil market at 3.9% CAGR. Suppliers with long test records on running programs face fewer delays at approval.

Country	CAGR, 2026 to 2036
Poland	5.9%
Mexico	5.6%
Brazil	5.3%
Italy	5%
USA	4.6%
Germany	4.3%
Japan	3.9%

How do Country-level CAGRs Compare in the Acoustic Liners Market?

FMI's analysis points to a clear split between emerging aerospace hubs and mature markets. The country CAGR chart sorts the seven profiled countries into three growth bands, with Poland at the top and Japan at the bottom. Demand in Poland and Mexico is projected to grow fastest during the forecast period, at 5.9% and 5.6% CAGR, as both countries are adding engine part and aerostructure plants for programs in the aircraft nacelle market. Brazil and Italy are expected to follow at 5.3% and 5% through 2036, with growth coming from Embraer programs and European supply chain investment. Demand in the USA will be driven by the largest OEM and MRO base, though a mature fleet is expected to hold growth to 4.6%. Germany, at 4.3%, and Japan, at 3.9%, will grow slowest by 2036, as buyers in both countries focus on research-led compact liners for existing programs. New engine options are expected to add work across all seven countries, as the composite pylon fairing systems for new engine options market is projected at 6.8% CAGR through 2036. Mature bases in the USA and Germany will still generate larger liner revenue, as Poland and Mexico grow from smaller program bases.

• Poland is set to post the fastest growth in the group at 5.9% CAGR through 2036. Demand is driven by the Aviation Valley cluster taking on more nacelle and aerostructure work for European programs.
• Safran engine part plants are pulling liner demand closer to North American programs, putting Mexico second at 5.6% during the forecast period.
• Brazil is expected to grow at 5.3% CAGR through 2036. Sales are driven by rising Embraer commercial and executive jet output, which keeps Brazil ahead of Italy.
• European supply chain investment in aerospace is expected to push demand for acoustic liners in Italy up by 5% a year through 2036.
• Growth in the USA is projected at 4.6% CAGR through 2036, slower than the emerging hubs. Demand will be driven by the largest OEM and MRO base, with replacement orders adding to serial production.
• At 4.3% CAGR through 2036, Germany will grow on steady A320 family output from the Hamburg final assembly lines.
• Japan is expected to record the slowest growth at 3.9% during the forecast period, as buyers adopt new liners mainly through engine research programs on compact designs.

CAGR estimates for more than 30 national and grouped markets across seven regions are available in the full report.

Country Outlook

• Poland's Aviation Valley groups 193 entities with more than 35,000 staff and 90% of the sector's output [8]. Such a dense cluster gives nacelle and aerostructure buyers short supply routes, due to which panel makers inside the cluster are receiving more European program work. As a result, demand for acoustic liners in Poland is projected to grow at 5.9% CAGR through 2036, the fastest among the profiled countries.
• Sales of acoustic liners in Mexico are projected to rise at 5.6% CAGR through 2036. Safran runs 20 sites in the country with more than 15,000 employees, including parts for CFM56 and LEAP engines [9]. This engine base is expected to pull liner qualification closer to Mexican plants and shorten delivery routes for North American programs.
• Key drivers of demand for acoustic liners in Brazil include regional and business jet output. Embraer delivered 78 commercial jets and 155 executive jets in 2025 [10]. Each program needs liners in different cabin and nacelle sizes, and suppliers approved on several Embraer programs will receive repeat orders as Brazil grows at 5.3% CAGR through 2036.
• Adoption of acoustic liners in Italy is expected to grow at 5% CAGR during the forecast period, supported by European aerospace supply chain investment. Italian suppliers buy through European program structures with strict traceability rules, so each order requires full lot records and approved materials. Panel makers aligned with Tier 1 purchase cycles are expected to receive more orders.
• Ownership changes are reshaping liner sourcing in the USA. Boeing completed the acquisition of Spirit AeroSystems in December 2025, adding commercial and aftermarket operations in Wichita, Dallas and Tulsa [6]. Contracts moving under Boeing ownership are expected to favour suppliers already approved on Boeing programs, and demand in the USA will grow at 4.6% CAGR through 2036 on both serial and replacement orders.
• Germany is projected at 4.3% CAGR through 2036, with demand anchored in single-aisle production. Hamburg operates four of the ten A320 family final assembly lines in the Airbus network [3]. High output on these lines keeps German buyers focused on lightweight liners for single-aisle nacelles.
• Engine research sets the pace of liner demand in Japan. JAXA is developing sound-absorbing technology that delivers high noise reduction from a smaller liner area [5]. Buyers approve compact liners only after test validation, due to which Japan is expected to record the slowest growth in the group at 3.9% CAGR by 2036.

Who are the Notable Companies in the Acoustic Liners Market?

Safran Nacelles, Collins Aerospace, Spirit AeroSystems, FACC, Hexcel and The Gill Corporation are among the notable companies profiled by FMI across nacelle structures, cabin systems and core materials.
