【摘要】 碳纤维由于具有比重小、比强度高、比模量高、耐腐蚀、高温强度高等特点,已成为最有前途的一种增强纤维。用廉价石油渣制备沥青基碳纤维更具有吸引力。 在试验室及中间实验装置上已成功地制得了通用型石油沥青基长纤维及短纤维。本文介绍了由石油渣油经调制处理、纺丝、不熔化及碳化处理制得碳纤维的过程。所得碳纤维抗拉强度为686.5MPa。更多还原

【Abstract】 Making carbon fibres from low-cost petroleum pitch is (he most attractive mcthod to produce commercial carbon fibres.Isotropic carbonaceous pitch-base continuous and short carbon fibres have made successfully at both laboratory and pilot plant. The pretreatment of petroleum sludge to make precursor, the spinning process, infusibiliza tio n and carbonization treatment are described. The tensile strength of carbon fibres is about 686.5 MPa.更多还原
