Durability and Damage Tolerance of Bismaleimide Composites. Volume 2. Appendix of Crack Growth and Low-Velocity Impact Data
Abstract
This program was the evaluation of durability and damage tolerance of bismaleimide (BMI) composites. BMI resins have been developed for structural applications in 350F to 450F environments. The represents an improvement over epoxy resin capability of approximately 100F. In Task 1 of this program we experimentally evaluated two second generation BMI systems (IM6/3100 and IM6/ F650) and compared their performance with that of baseline systems AS1/3501-6 and T300/V378A. the intermediate modulus fiber IM6 was chosen as the common fiber for both material systems because its high strength and stiffness are properties that are important for future fighter design. In Task II basic material properties were determined. The data included moisture absorption, glass transition temperature, thermal spike susceptibility, lamina properties, and interlaminar fracture toughness test results. Lamina properties and fracture toughness test data were used to correlate laminate behavior exhibited in Task III. Keywords: Composite materials; Tough resins; Static strength; Bismalemide; Stress analysis; Low energy impact; Damage tolerance.
