Abstract
Damage development and fracture in notched woven fabric GFRP laminates have been studied, using specimens with central circular holes of a range of sizes. Fracture mechanics tests have also been carried out, using a single-edge-notch geometry. A comprehensive notch edge damage analysis was performed by a combination of recording tests on video, plan view photography and a deply technique, enabling a layer by layer analysis. It was shown that the notch edge damage initiation and propagation comprised matrix cracking, fracture of the 0° tows, delamination and longitudinal splitting. The tows in the fabric layers oriented at 45° within the damage zone remained intact up to the maximum load in a tensile test.
