Fracture Toughness of Chopped Glass Fibre Phenolic Composite

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.
