【摘要】：碳纖維增強復(fù)合材料在固化成型過程中,其溫度與固化度的變化歷程具有強耦合關(guān)系,以含有非線性內(nèi)熱源的瞬態(tài)熱傳導(dǎo)方程為基礎(chǔ),利用有限容積法編寫了計算程序,研究了以T300/環(huán)氧預(yù)浸料為材料的某復(fù)合材料工字形地板梁在先進拉擠工藝下的溫度、固化度的變化歷程。結(jié)果表明:該工字形地板梁在厚度為5.9 mm時,固化過程中的溫度場和固化度場基本可以認為是均勻的,其厚度不會對固化質(zhì)量產(chǎn)生較大影響;當該工字梁的厚度達到11 mm時,制件最高溫度比模具溫度高出了10.7℃,這時制件厚度已對制件的固化質(zhì)量產(chǎn)生較大影響。
[Abstract]:During the curing process of carbon fiber reinforced composites, the variation of temperature and curing degree has a strong coupling relationship. Based on the transient heat conduction equation with nonlinear internal heat source, the calculation program is compiled by the finite volume method.The change process of temperature and curing degree of a composite I-shaped flooring beam with T300 / epoxy prepreg under advanced pultrusion process was studied.The results show that when the thickness of the I-shaped floor beam is 5.9 mm, the temperature field and curing degree field in the curing process can be considered to be uniform, and the thickness of the I-shaped floor beam will not have a great effect on the curing quality, and when the thickness of the I-shaped floor beam reaches 11 mm,The maximum temperature of the parts is 10.7 鈩，
