Abstract
The object of this study is to investigate the size effect and cryogenic fracture characteristics of G-11 woven glass-epoxy laminates. Fracture toughness tests were carried out with compact tension (CT) specimens at room temperature and 77 K. CT specimens with different widths and thicknesses were tested in accordance with ASTM E399-83, ASTM E813-89 and JSME S001. The results showed that the apparent fracture toughness are strongly influenced by specimen size. The damage morphology around the notch tip of tested specimens was characterized using a microscope. The damage occurred with increasing applied load, and the interaction of the damage zone and the size effect in fracture was exhibited.
