| Abstract: | A prestress technique together with film stacking was adopted to prepare the carbon fiber （CF）?reinforced polycarbonate （PC） laminates. The tensile strength of the resultant laminates applied with different prestress levels was measured. The tensile fracture morphology of the laminates was characterized with scanning electron microscopy， and the alignment of CF in the PC matrix was observed using an optical microscope and a camera. The result indicated that the alignment of CF was improved with an increase in prestress level. The tensile strength of the laminates showed an increasing rend at first and then a decrease with an increase in prestress， and it increased by 10.66 % and 11.78 % compared to the lowest parts on both sides. However， the tensile modulus showed no relationship with the prestress. |
