This paper describes the experimental evalu-ation results of the tensile and flexural test concerning with 17 kinds of high strength 2D carbon/carbon composites at the room temper-ature. The effects of specimen shape on the tensile strength were examined by using three types of specimens (contour, dumbbell and cou-pon type). The results show that maximum tensile strength level is improved higher than 700 MPa. The main tensile fracture pattern illustrated fiber pull-out, whereas interlaminar shear frac-ture dominated in flexural test, especially about higher tensile strength materials. A coupon type and a contour type specimen are considered more suitable than dumbbell type as the tensile evaluation specimen of carbon/car-bon composite at the room temperature. There were not the definite correlation between tensile and flexural strength of PAN based carbon fiber types. A kind of network structure was observed as a particular substructure of carbon/carbon com-posite materials.
