【発明の名称】ピッチ系炭素繊維三次元織物の製造法
Document Type and Number:
Japanese Patent JP2648711
Kind Code:
B2
Abstract:
Three dimensional woven fabrics containing, at least as one component thereof, the carbon fibers obtained by thermosetting treatment and carbonization treatment carried out after melt-spinning of high softening point pitch and having a tensile strength of 15 - 250 Kgf/mm<2>, elongation of 0.5 - 8.0% and modulus of elasticity of 400 - 40,000 Kgf/mm<2> and a capability of increasing both of their tensile strength and modulus of elasticity to 1.1 times or more of the values before additive heat-treatment by way of the additive heat-treatment carried out under a relaxed state of the said carbon fibers are provided, whereby carbon fibers having a tensile strength of 150 Kgf/mm<2> or more and a modulus of elasticity of 40,000 Kgf/mm<2> or more are attained. They are superior in abrasion-resisting property, flexion-resisting property and scratch-resisting property and useful as one component of fiber composite materials in reinforcing plastics, metals, cements, ceramics, carbon materials, etc.
