A Study on the Mechanical Performance of Aramid-Epoxy Laminated Composites with Plain and Twill Woven Structure/Fabric Architecture
In the present study,the mechanical properties and failure behavior of aramid/epoxy plain and twill weave laminat-ed composites have been investigated.Aramid fiber plain and twill woven fabric and epoxy resin was used to prepreg prepara-tion.The hotpress molding technique and fabric resin(epoxy)prepreg were used to prepare laminated composite plates.This research aims to find the effect of the fabrics weaving patterns on the mechanical performance of the laminated composites.For this purpose,compressive strength,short beam shear strength,and flexural strength were investigated by the Universal Testing Machine(UTM)according to the ASTM standards.All tests were performed in warp directional loading.Finally,the fracture mechanism was observed from the images taken by the optical microscope.According to test results,it was found that twill fabric reinforced composites have better mechanical performance compared to plain fabric composites.Due to the long floating length,low crimp percentage,and uniform resin impregnation was generated in twill fabric composites.On the other hand,plain fabric composites have inadequate mechanical performance because of the high crimp percentage and uneven ma-trix impregnation at the interlacement region.
