Fracture, Longevity (Fatigue), Dynamics, and Aeroelasticity of Composite Structures.

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.
