Materials Characterization for Matrix-Dominated Failure Modes

Source

Viable test methods that may be used in characterizing matrix-dominated composite properties are assessed. Special emphasis is placed on matrix cracking and delamination. Both strength characterization and fracture mechanics test methods are considered. Transverse tension, in-plane shear, interlaminar shear, and a laminate test for in situ first-ply failure are the strength tests considered. Fracture mechanics test methods discussed include the double-cantilever-beam test, a 90-deg center-notch tension test, and a free-edge-delamination tension test.
