This work deals with the mechanical property of triaxial CFRP from low to high temperatures.We performed tensile tests on this composite at 100 K,room temperature and 373 K.Mechanical load was applied along both the axial and transverse directions,and the effects of temperature and loading direction on the fracture load were discussed.We also fabricated the triaxial CFRP with barium titanate nanoparticles,and examined the damping properties at room temperature.
