工艺因素对低温玻璃钢真空气密性的影响

THE EFFECTS OF PROCESSING ON THE CHARACTERISTIC OF VACUUM GAS-PROOF OF AN GLASS-FIBRE REINFORCED EPOXY COMPOSITE USED AT LOW TEMPERATURE

在低温玻璃钢的使用过程中,常常会遇到气密性的问题。尽管国内外有许多研究者对玻璃钢的放气及其渗透问题表示了很多的关注,但至今尚未见专门的有关低温玻璃钢真空气密性的研究报导。对于低温环境下使用的玻璃钢,行业内多以增设阻挡层或采用表面处理的方法,来提高其真空气密性,本文中仅从工艺角度,对提高低温玻璃钢的真空气密性做一定的探讨。

In course of using an Glass-Fibre Reinforced Epoxy Composite at low temperature, we meet the problem about Vacuum Cras-Proof. Although many researchers paid much attention to it, yet we haven＇t found a special report about it. For the FRP used at low temperature, people always improve Vacuum Gas-Proof with adding coat or surface preparation. In this paper, I discussed this issue in view of processing.
