ABSTRACT

Mode I interlaminar fracture behaviours were investigated on the laminated composites reinforced with plain glass woven fabrics which were treated with different silane concentrations. The low silane concentration specimen indicated higher fracture toughness, compared to the high silane concentration specimen. This is due to the occurrence of the micro crack in the fibre strands. In the low silane concentration specimen, larger damage zone due to the micro crack was formed ahead of the crack tip.
