着重研究了废弃玻璃纤维的模压成型技术，得到固化剂/环氧树脂=1:1最佳，综合考虑回收成本与制品性能，得到最佳成型条件为：废弃玻璃纤维质量/环氧树脂/固化剂=10:1:1，温度45℃，加热时间3h。并采用溶剂法从废弃玻璃纤维粉末中回收得到较纯净的玻璃纤维，得出温度为75℃，加热时间22h，酸液浓度为8mol/l，投料比为15g:100ml的分解条件较适宜。，
Emphatically studied has abandoned the glass fiber the mould pressing to take shape the technology, obtained the solidification to suppress epoxy resin =1:1 to be best, the synthesis considered the recycling cost and the product performance, obtained best takes shape the condition is: Abandons the glass fiber epoxy resin/solidification to suppress 10:1:1, warm 45 ℃, heats up time 3h. And uses the solvent extraction from to abandon in the glass fiber powder to recycle obtains the purer glass fiber, obtains the temperature 75 ℃, heats up time 22h, the acid liquor density is 8mol/l, compares the 15g:100ml decomposition condition comparatively to be suitable.
