Abstract

A new unidirectional Torray T700 carbon fibers-reinforced composite laminate based on Huntsman XB3585 epoxy resin has been developed in Resin Transfer Molding process with applications in the automotive industry. Numerical simulations have been carried out on this type of laminate subjected to off-axis loading systems to determine its most important elastic properties and compared to experimental data. Specimens cut from various plates axial, transverse and at ±45° to the fibers direction have been subjected to tensile and compression tests to determine axial and transverse Young’s moduli as well as axial-transverse shear modulus and Poisson ratio. The numerical simulations present close values to those determined experimentally. Stress-strain distributions as well as most common failure modes are presented..
