The Manufacture of Pitch-Base Carbon Fibres
-
摘要: 碳纖維由于具有比重小、比強度高、比模量高、耐腐蝕、高溫強度高等特點,已成為最有前途的一種增強纖維。用廉價石油渣制備瀝青基碳纖維更具有吸引力。
在試驗室及中間實驗裝置上已成功地制得了通用型石油瀝青基長纖維及短纖維。本文介紹了由石油渣油經調制處理、紡絲、不熔化及碳化處理制得碳纖維的過程。所得碳纖維抗拉強度為686.5MPa。Abstract: Making carbon fibres from low-cost petroleum pitch is the 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.-
