Bismaleimide (BMI) prepreg system Hexcel Corporation
HexPly® prepregs are specially formulated resin matrix systems, that are reinforced with man-made fibers such as carbon, glass and aramid. When cured at elevated temperatures, the themoset resin undergoes a chemical reaction that transforms the prepreg into a solid structural material that is highly durable, temperature resistant, exceptionally stiff and lightweight.
