Influence of Sizing Aging on the Strength and Fatigue Life of Composites Using a New Test Method and Tailored Fiber Pre-Treatment: A Comprehensive Analysis

Given the time-consuming and complex nature associated with aging of composites, a novel fabric pre-aging method was developed evaluated for static fatigue testing. It allows investigating sizing interphase-related effects. This fast is independent diffusion processes composites’ thickness. Moreover, new methodology offers enhanced analysis sizing, interphase, fiber-related degradation composites without them by conventional accelerated procedures or under severe maritime environments. For validation purposes, fiber bundle, longitudinal, transverse tensile tests were performed five different glass inputs. Significant differences in durability found classical aging, respectively. The impacts single constituents on life are identified cyclic testing untreated, pre-aged, wet-aged composites. Here, it evident that interphase strength likewise essential tension-tension performance unidirectional as itself. In summary, presented provides industry academia an additional opportunity to examine fibers, sizings, design purposes following reasonable methodology.
