摘要
采用恒神自研的TF2218 树脂搭配恒神自研的HF30B(T700 级)碳纤维制备出低孔隙率真空袋压预浸料,并对其含浸工艺和固化工艺进行研究.研究发现,在满足预浸料铺贴工艺性的前提下,预浸料含浸程度越低,最终制件的孔隙率越小,力学性能越高,与低含浸度相比,高含浸度制件力学性能下降了12%左右;同时固化时导气材料的存在能够对制件质量和力学性能产生一定帮助,导气材料的存在使得力学性能提高了4%左右.
Abstract
Low porosity vacuum bag pressing prepreg was prepared using Hengshen self-developed TF2218 resin and Hengshen self-developed HF30B(T700 grade)carbon fiber,and its impregnation process and curing process were studied.It was found that under the premise of meeting the processability of prepreg paving,the lower the degree of impregnation of the prepreg,the smaller the porosity of the final product,and the higher the mechani-cal properties..Compared with low impregnation,the mechanical properties of high impregnation products de-crease by about 12%.At the same time,the presence of conductive materials during simultaneous curing can help improve the quality and mechanical properties of the workpiece product,and the presence of conductive materials increases the mechanical properties by about 4%.
