A new needled cylindrical preform was designed and fabricated in this paper by means of angle plies
of continuous wound carbon fibers with a twill fabric and non鄄woven tapes needled preform as basements. The effects
of needled preform structures on the mechanical properties of C/ C composites were compared and investigated. The
results show that the orthogonal needled C/ C composite with the non鄄woven tapes has higher interlaminar shear
strength(ILSS), and a higher axial tensile strength of 157. 0 MPa, being 83. 0% higher than that of the twill fabric
reinforced. The non鄄woven tapes reinforced cylindrical C/ C composites with different angles have improved ILSS and
axial tensile properties, the maximum ILSS and axial tensile strength reach 11. 68 MPa and 179. 0 MPa respectively,
being 22. 6% and 14%,respectively,higher than that of the orthogonal C/ C composite.
