摘要: Axial compressive behaviour of reinforcing fibres and interphase in glass fibre/epoxy resin composites were examined. strengths evaluated by the tensile recoil method. The effects silane-based coupling surface treatment agent on fibre investigated. showed higher when coated treatment. Interphase was also investigated means single-fibre embedded test. particular stress strain distributions inside specimen examined a three-dimensional finite element analysis. parameter “interfacial transmissibility” instead conventional critical length theory introduced as an index interfacial properties. This useful to estimate properties at elastic state apart from complicated state. It confirmed that improved glass/epoxy under axial load.
