Thermal Shock Behavior of Twill Woven Carbon Fiber Reinforced Polymer Composites

In the current research, effect of cyclic temperature variation on mechanical and thermal properties woven carbon-fiber-reinforced polymer (CFRP) composites was investigated. To this, carbon fiber textiles in twill 2/2 pattern were used as reinforced phase epoxy, CFRPs fabricated by vacuum-assisted resin-infusion molding (VARIM) method. Thermal cycling process carried out between −40 +120 °C for 20, 40, 60 80 cycles, order to evaluate CFRP specimens. this regard, tensile, bending short beam shear (SBS) experiments out, obtain modulus elasticity, tensile strength, flexural modulus, strength inter-laminar (ILSS) at room (RT), then treated compared. A dynamic analysis (DMA) test properties, viscoelastic such storage (E’), loss (E”) factors (tan δ), evaluated. It observed that characteristics affected due post-curing a high temperature. This worked crosslink improve composite behavior or degrade it different coefficients expansion (CTEs) components. The response determined interaction these phenomena. Based SEM observations, delamination, pull-out bundle breakage dominant fracture modes tensile-tested
