碳纖維管測定報(bào)告

1、兩種碳纖維管彈性模量及強(qiáng)度測定報(bào)告 碳纖維管（如圖0-1）作為一種新型高強(qiáng)材料，已在軍事及民用工業(yè)的各個(gè)領(lǐng)域取得廣泛應(yīng)用。從航天、航空、汽車、電子機(jī)械、化工、輕紡等民用工業(yè)到運(yùn)動(dòng)器材和休閑用品等。不同生產(chǎn)廠商的加工工藝和生產(chǎn)成分的不同都會(huì)導(dǎo)致其功能屬性的差異。在這里爭對兩種碳纖維管進(jìn)行強(qiáng)度和彈性模量測定。0-1：碳纖維管一 實(shí)驗(yàn)?zāi)康?、 測定碳纖維管的強(qiáng)度及彈性模量；2、 了解不同制作環(huán)境下，碳纖維管彈性模量及強(qiáng)度及彈性模量的區(qū)別；3、 通過實(shí)驗(yàn)方案設(shè)計(jì)，提高分析問題和解決問題的能力；二 試驗(yàn)原理及方法1、碳纖維管強(qiáng)度的測定碳纖維管強(qiáng)度是指碳纖維管在規(guī)定的荷載下，材料發(fā)生破壞時(shí)的應(yīng)力。在這里通

2、過加載試驗(yàn)機(jī)對碳纖維管縱向施加豎向荷載（如圖2-1所示），加載至材料破壞，記錄荷載大小Fmax，測定碳纖維管截面S，其強(qiáng)度可表示成=FmaxS。圖2-1：試件加載2、 碳纖維管彈性模量的測定碳纖維管彈性模量測量是通過其應(yīng)力應(yīng)變的關(guān)系來求得。將兩種不同的纖維管分別截取長度為90mm的三個(gè)試樣，分別標(biāo)記為1-1（第一種試件1）、1-2、1-3、2-1（第二種試件1）、2-2、2-3（如圖2-1左）；分別在中間橫截面上取兩個(gè)對稱位置貼取應(yīng)變片（如圖2-1右），在試驗(yàn)機(jī)上加載F，求出該截面應(yīng)力=FS，并用應(yīng)變儀測定實(shí)時(shí)應(yīng)變，通過計(jì)算機(jī)優(yōu)化擬合得出-曲線得出斜率K，則相應(yīng)彈性模量E=K。圖2-1：左：樣
