Effects of Geometric and Material Parameters on Behavior of Fiber Composites

摘要

The objective of this investigation is to study the effects of constituentproperties (fiber, matrix, interphase) and geometric parameters (fiber volume ratio, fiber packing) on the overall behavior of brittle matrix composites. Four model composite materials were studied, a silicon carbide fiber/barium borosilicate glass system, a polyvinyl alcohol fiber/epoxy system, and two optic fiber/epoxy systems. Single fiber tests were used to characterize interfacial properties. Multiple fiber composite models were made and tested and failure mechanisms observed and analyzed.
