重慶建筑加固　碳纖維布加固的原理
 
用于建(jian)筑(zhu)結(jie)構加(jia)(jia)固(gu)(gu)(gu)的碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)材料具有優良的力(li)學(xue)性(xing)能(neng)，其抗拉強度一般(ban)為建(jian)筑(zhu)用鋼(gang)材的十(shi)幾倍；但是，碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)材料織成碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)布后，其中的各碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)絲很難完全共(gong)同工(gong)(gong)(gong)作，在承(cheng)受較(jiao)(jiao)低的荷(he)載時，一部分應(ying)力(li)水平較(jiao)(jiao)高(gao)的碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)絲首先達(da)到(dao)其抗拉強度并退出工(gong)(gong)(gong)作狀態，以此類(lei)推，各碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)絲逐漸(jian)斷裂(lie)，直至整體破壞。而使(shi)用粘(zhan)結(jie)劑后，各碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)絲能(neng)很好(hao)地(di)共(gong)同工(gong)(gong)(gong)作，大大提高(gao)碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)布的抗拉強度，故碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)加(jia)(jia)固(gu)(gu)(gu)首先必須使(shi)碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)布中的碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)絲能(neng)共(gong)同工(gong)(gong)(gong)作，因此粘(zhan)結(jie)劑對(dui)碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)布的加(jia)(jia)固(gu)(gu)(gu)起著(zhu)關鍵的作用，它既要(yao)確(que)保各碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)絲共(gong)同工(gong)(gong)(gong)作，同時又確(que)保碳(tan)(tan)(tan)(tan)纖(xian)(xian)(xian)(xian)維(wei)(wei)(wei)(wei)布與結(jie)構共(gong)同工(gong)(gong)(gong)作，從(cong)而達(da)到(dao)加(jia)(jia)固(gu)(gu)(gu)的目(mu)的。
