碳纤维杆--碳纤维按原料的分类介绍

碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)按原料(liao)(liao)来(lai)源可(ke)(ke)分为(wei)(wei)聚(ju)丙烯(xi)腈(jing)基(ji)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)、沥青基(ji)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)、粘胶基(ji)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)、酚醛基(ji)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)、气相生长碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei);按性(xing)(xing)能可(ke)(ke)分为(wei)(wei)通用型(xing)(xing)(xing)(xing)、高强(qiang)型(xing)(xing)(xing)(xing)、中模(mo)(mo)高强(qiang)型(xing)(xing)(xing)(xing)、高模(mo)(mo)型(xing)(xing)(xing)(xing)和(he)(he)超高模(mo)(mo)型(xing)(xing)(xing)(xing)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei);按状态分为(wei)(wei)长丝(si)、短(duan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)和(he)(he)短(duan)切纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei);按力学性(xing)(xing)能分为(wei)(wei)通用型(xing)(xing)(xing)(xing)和(he)(he)高性(xing)(xing)能型(xing)(xing)(xing)(xing)。通用型(xing)(xing)(xing)(xing)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)强(qiang)度(du)(du)为(wei)(wei)1000兆(zhao)帕(pa)、模(mo)(mo)量(liang)为(wei)(wei)100G帕(pa)左右(you)。高性(xing)(xing)能型(xing)(xing)(xing)(xing)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)又分为(wei)(wei)高强(qiang)型(xing)(xing)(xing)(xing)(强(qiang)度(du)(du)2000兆(zhao)帕(pa)、模(mo)(mo)量(liang)250G帕(pa))和(he)(he)高模(mo)(mo)型(xing)(xing)(xing)(xing)(模(mo)(mo)量(liang)300G帕(pa)以(yi)上)。强(qiang)度(du)(du)大(da)于4000兆(zhao)帕(pa)的(de)又称为(wei)(wei)超高强(qiang)型(xing)(xing)(xing)(xing);模(mo)(mo)量(liang)大(da)于450G帕(pa)的(de)称为(wei)(wei)超高模(mo)(mo)型(xing)(xing)(xing)(xing)。随着航天和(he)(he)航空工业的(de)发(fa)展，还(hai)出现了(le)高强(qiang)高伸型(xing)(xing)(xing)(xing)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)，其延伸率大(da)于2%。用量(liang)最大(da)的(de)是聚(ju)丙烯(xi)腈(jing)PAN基(ji)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)。市场上90%以(yi)上碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)以(yi)PAN基(ji)碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)为(wei)(wei)主。由于碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)神秘的(de)面纱尚(shang)未完全揭开，人们还(hai)不能直接用碳(tan)(tan)(tan)(tan)或石墨来(lai)制取，只能采(cai)用一些含(han)碳(tan)(tan)(tan)(tan)的(de)有机(ji)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)(如尼龙丝(si)、腈(jing)纶(lun)丝(si)、人造丝(si)等)为(wei)(wei)原料(liao)(liao)，将有机(ji)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)与塑料(liao)(liao)树脂结合在一起炭化(hua)制得碳(tan)(tan)(tan)(tan)纤(xian)(xian)(xian)(xian)(xian)(xian)维(wei)(wei)(wei)。
