碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)的化(hua)学性(xing)(xing)质与碳(tan)相识，它除能被强(qiang)(qiang)氧(yang)(yang)化(hua)剂(ji)(ji)氧(yang)(yang)化(hua)外(wai)，对一般(ban)碱性(xing)(xing)是惰性(xing)(xing)的。在空气(qi)中温度高(gao)于400℃时(shi)则(ze)出现明显的氧(yang)(yang)化(hua)，生成CO与CO2。碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)对一般(ban)的有(you)机溶剂(ji)(ji)、酸(suan)(suan)、碱都具有(you)良好的耐(nai)(nai)腐蚀(shi)性(xing)(xing)，不溶不胀，耐(nai)(nai)蚀(shi)性(xing)(xing)出类拔萃(cui)，完全不存(cun)在生锈的问题。[11]有(you)学者在1981年将PAN基(ji)碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)浸泡在强(qiang)(qiang)碱氢氧(yang)(yang)化(hua)钠溶液中，时(shi)间已(yi)过(guo)去30多(duo)年，它仍保(bao)持纤(xian)(xian)(xian)维(wei)(wei)(wei)形态。但其耐(nai)(nai)冲击性(xing)(xing)较差，容易(yi)损伤，在强(qiang)(qiang)酸(suan)(suan)作(zuo)用(yong)(yong)下发生氧(yang)(yang)化(hua)，碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)的电(dian)动(dong)(dong)势为(wei)正值，而铝(lv)合(he)(he)金的电(dian)动(dong)(dong)势为(wei)负值。当碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)复合(he)(he)材料(liao)与与铝(lv)合(he)(he)金组合(he)(he)应用(yong)(yong)时(shi)会发生金属碳(tan)化(hua)、渗(shen)碳(tan)及电(dian)化(hua)学腐蚀(shi)现象。因(yin)此(ci)，碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)在使用(yong)(yong)前须进行表面处理。[4]碳(tan)纤(xian)(xian)(xian)维(wei)(wei)(wei)还有(you)耐(nai)(nai)油、抗辐射(she)、抗放射(she)、吸收有(you)毒气(qi)体和减速中子等特性(xing)(xing)。
