Influence of thermal and microwave processing on the mechanical and interfacial properties of a glass/epoxy composite

The influence of two curing methods, namely thermal and electromagnetic radiation (microwave) curing, on the mechanical properties of a glass fibre/epoxy model composite has been studied. The advantage of microwave processing is that it leads to significantly faster curing times compared to thermal processing. The influence of processing technique on the mechanical and interfacial properties was determined. The interfacial properties considered include the interfacial shear (bond) strengthτi, the matrix shrinkage pressure on the fibrePo, the interfacial coefficient of friction μ and the interfacial frictional shear stressτf. The interfacial properties were determined from analysis of experimental data from pull-out tests. Based on these results, the effect of thermal and microwave processing on the mechanical properties of the glass fibre/epoxy composite system was elucidated.
