MARKET INSIGHTS
Global Carbon Nanotube (CNT) Sheet as Lightning Strike Protection (LSP) Material Market size was valued at USD 98.4 million in 2025. The market is projected to grow from USD 107.6 million in 2026 to USD 243.8 million by 2034, exhibiting a CAGR of 9.5% during the forecast period.
Carbon nanotube (CNT) sheets are advanced nanomaterial-based structures engineered to provide effective lightning strike protection in aerospace and defense applications. These lightweight, highly conductive sheets function by rapidly dissipating electrical energy from a lightning strike across the surface of composite structures, significantly reducing localized thermal and mechanical damage. CNT sheets are increasingly being integrated into aircraft fuselages, wing skins, and nacelles as a next‑generation alternative to conventional copper mesh and expanded metal foil systems, offering superior electrical conductivity, reduced weight, and compatibility with carbon fiber reinforced polymer (CFRP) composites.
The market is gaining strong momentum driven by the rapid expansion of next‑generation commercial and military aircraft programs, growing adoption of lightweight composite airframes, and increasing regulatory emphasis on lightning protection standards such as SAE ARP5412 and DO-160. Furthermore, the commercial aviation sector’s push toward fuel efficiency has accelerated the shift from heavier metallic LSP solutions to CNT‑based alternatives. Key players actively advancing this space include Nanocomp Technologies (a Huntsman company), Toray Industries, Inc., and Hexcel Corporation, among others contributing to material innovation and qualification efforts across major aerospace OEM supply chains.
