Aerospace & Defense Core Materials Market

The aerospace and defense core materials market is set to grow from USD 0.47 billion in 2025 to around USD 0.88 billion by 2030, at a 13.3% CAGR. A big part of this rise comes from the industry’s ongoing shift toward lighter and stronger structures. Aircraft makers, defense programs, and even emerging UAV platforms are relying more on honeycomb and foam cores to improve performance and reduce overall weight. As countries invest in new aircraft and upgrade older fleets, the demand for these materials naturally goes up. There is also steady progress in manufacturing methods, enabling engineers to use these materials in more areas than before. Altogether, these trends are pushing the market forward at a healthy pace.

Some of the major manufacturers operating in the aerospace & defense core materials market are include Hexcel Corporation (US), Plascore Incorporated (US), Gill Corporation (US), SCHÜTZ Composites (Germany), Corex Honeycomb (UK), Euro-Composites (Luxembourg), Gurit Holding AG (Switzerland), ACP Composites (US), Diab Group (Sweden), Armacell International (Luxembourg), General Plastics Manufacturing Co. (US), Evonik Industries (Germany), SABIC (Saudi Arabia), Kineco Limited (India), HONYLITE Pvt. Ltd. (India), and 3A Composites (Switzerland).
