摘要：Composite materials are replacing standard engineering metals and alloys for many applications. Their inherent ability to be custom tailored for any application has made fiber reinforced composites. Their superior specific strength and stiffness characteristics have made them very competitive in the industry. The primary limitation of fiber reinforced composites is fracture toughness, specifically delaminating. Delaminating failures are common due to the nature of composite construction. In this study, attempt to distinguish interlaminate fracture toughness of composite laminates along the interface of composite laminates for three type of material. The four end notched flexural (4ENF) test is conducted to investigate the effects of the previous materials on the Mode I and Mode II interlaminate fracture toughness, respectively
