【 摘 要 】

The chopped glass fibre phenolic Composite to be used for the construction of aircraft parts has been prepared and the fracture toughness of this composite was evaluated using J-integral method. The effects of humidity and 3 per cent NaCl on the fracture toughness values were also investigated. For this, a set of six specimens having crack lengths varying from 0-18 mm was tested. Five such sets of specimens were selected for the experimental studies to check the reproducibility of the results and to evaluate the effect of environment.
