| الوصف: | This study focuses on mechanism on thermal residual stress formation in fibre reinforced polymer (FRP) composites. It proposed that the threshold temperature for thermal residual stress formation during the curing process of FRP composites is the gel temperature (Tgel) of resin matrix. An equation is used to characterise the relationship between thermal deformation and temperature. A model of the basic principle for the micro-scale thermal residual stress of FRP composite is established and the calculation formula is derived. The mechanism is verified by testing on carbon fibre reinforced polymer (CFRP) composites via RTM process and finite element analysis (FEA), which calculates cure shrinkage deformation of FRP specimen theoretically. The shrinkage deformation results from RTM specimens coincide with those from the FEA simulation. |
