Abstract : The results of several investigations into the fracture, longevity (fatigue), dynamics, and aeroelasticity of composite materials are reported. The experimental work was conducted using Hercules graphite/epoxy prepreg in two forms: AS1/3501-6 unidirectional tape and A370-5H/3501-6 fabric. The topics discussed include unnotched tensile fracture, sensitivity to notches under tensile loading, nonlinear stress-strain behavior, compression specimen development, damage growth under cyclic load, and the flutter and divergence of graphite/epoxy wings.
