Interlaminar Fracture Toughness in Resin Matrix Composites.
Abstract
This annual report summarizes the objectives, accomplishments and proposed new directions of research on mode II interlaminar fracture in resin matrix composites. A mode II interlaminar fracture specimen, test and analysis method for interpreting results have been successfully developed and demonstrated for the AS4/3502 material system. Experimental data have been obtained under both net tensile and compressive loading. Of considerable importance are the findings that (1) the AS4/3502 material system shows increasing resistance to crack growth in tension, (2) interlaminar fracture under compression is a totally unstable process, and (3) tension and compression behaviors are considerably different. The findings and the conclusions that are drawn from them point to new, promising directions for the work. Two new central directions that are suggested involve failure analysis using fractography, radiography and ultrasonic inspection and the quantitative evaluation of mode I suppression technology utilizing the new testing method. Papers, reports and presentations resulting from this research are listed. Originator furnished keywords include: Delamination; Interlaminar fracture; Composite materials; Composite structures; Fracture testing; Mode II fracture; and Fracture.
