AS4 (Hercules) carbon fibre in a 5250-3 (Narmco) bismaleimide matrix, supplied as tape. Carbon/BMI extends carbon/epoxy to sustained service around 350-450 °F, well beyond epoxy's limit, while processing in broadly similar tooling. It is used for engine nacelles and nozzles, structure near exhaust, and supersonic-aircraft skins subject to aerodynamic heating. The handbook characterises it from -67 °F to 450 °F, consistent with elevated-temperature service. MatWorld carries 16 tensile, compressive and shear curves for this system, digitised from MIL-HDBK-17-2F Volume 2 (US Government work, public domain).
