摘要
Novel carbon/glass hybrid thermoplastic composite rods having different carbon/glass ratios (24K1P,24K2P,and 24K3P) are commercially fabricated.The transverse compressive properties of these three hybrid rods were investigated.The load-displacement curve showed large nonlinear behavior and a complicated shape.In the initial stage,the load gradually increased by increasing the deformation.In the second stage,the load-displacement relation was almost linearly proportional to the displacement (stable deformation region).Subsequently,the slope decreased slightly,before the load-displacement curve showed a clear slope increase as the deformation proceeded.The fracture behavior of the hybrid rods was examined using a digital microscope.The observed fracture paths formed almost straight lines running through the loading point,the center of the cross section of carbon fiber bundles/thermoplastic epoxy,as well as the interface between the glass fiber bundles/thermoplastic epoxy and the carbon fiber bundles/thermoplastic epoxy.
