Numerical investigation of the hybridisation mechanism in fibre reinforced hybrid composites subjected to flexural load

摘要: Abstract Whilst the presence of a hybrid effect for flexural strength polymer matrix composites has been noted by several researchers, reasons behind such phenomenon remain unclear. In this work authors have investigated hybridisation on carbon/glass fibre reinforced epoxy with aim elucidating mechanisms effect. Classical lamination theory (CLT) and finite element analysis (FEA) were employed to determine stress distribution within maximum allowable load at first ply failure (FPF) apparent being determined based four commonly used theories, namely, stress, strain, Azzi-Tsai-Hill Tsai-Wu. Using results analysis, general rules improvement in proposed. Through application these it was shown that positive could be achieved both unidirectional bidirectional when an optimal stacking configuration used. Furthermore, predicted different theories compared obtained using Tsai-Wu significantly from other under certain circumstances, particular situations laminas contained angles and/or materials. Overall is hoped explanation together design outlined will lead improved optimization composites.
