Interlaminar fracture of carbon fabric reinforced carbon composites with different volume fractions of reinforcement (Vf = 36 - 60 %) was investigated by tensile loading of double-notched specimens. Dynamic tensile and in-plane shear moduli of all materials increased with increasing Vf. The interlaminar shear strength yielded maximum values for specimens with volume fraction Vf ~ 48 %. After graphitisation, the in-plane shear modulus fell remarkably which is probably due to "stress graphitisation" of the matrix.
