摘要: Abstract The longitudinal compressive properties of carbon fiber/nanoparticles reinforced polymer unidirectional composites are investigated by experiments and a series numerical simulations based on fast Fourier transforms (FFT) method taking into consideration matrix plastic behavior initial fiber waviness. efficient accurate FFT-based is convenient has the low computation cost to discuss effects material geometric parameters strength in details. proper filling nanoparticles can significantly increase strength. computational results for failure mechanisms show good consistency with our experimental results. present study provides reliable guidance designing better damage tolerance.
