Aerospace Heat- and impact-resistant prepreg for aerospace applications

摘要

A carbon fibre-reinforced bismaleimide (BMI) prepreg that is resistant to high temperatures and impacts has been developed by Teijin for the production of parts for aerospace engines. Teijin claims that its BMI prepreg possesses a glass-transition temperature (T ) of 280°C while at the same time demonstrating a compression-after-impact (CAI) strength of 220 MPa when tested according to the Suppliers of Advanced Composite Materials Association's method SRM-2.
