Delamination Failure of a Woven Glass Fiber Composite

摘要: Delamination fracture of a woven glass fiber composite was studied with the double cantilever beam (DCB) test. The mechanism stop-start crack propagation determined by direct observation front, complemented fractographic analysis. results were compared an earlier study interlaminar that considered effect yarn undulation without weave. constraint imposed interwoven fill yarns forced from intrayarn path to interply which approximately doubled toughness. Increasing matrix toughness increasing amount soft segment in urethane methacrylate resin translated directly increased resin-rich regions, especially interstitial areas where four intersected, strongly influenced propagation. In most brittle matrix, these regions fractured ahead front and thus served as internal flaws or weak po...
