Abstract

An innovative recycling process for thermoset composite laminates is proposed by thermo-mechanical disassembly and further compression molding of hybrid thermoformable composite plates. Due to the thermo-mechanical process, single cured plies are extracted from the waste laminate. Subsequently re-lamination is performed by interposing thermoplastic films between the reclaimed composite plies. Final consolidation is carried out by compression molding. In order to show the feasibility of the novel recycling technology, carbon fiber reinforced composite plates by autoclave molding were thermo-mechanically disassembled in a manual roll bending machine after heating in oven. Reclaimed cured plies were laminated by alternating thermoplastic interlayers made of low density polyethylene. The hybrid laminate was consolidated at the temperature of 220�C and the holding pressure of 38.5 bar. Results from bending tests on virgin and recycled plates showed the very good agglomeration of the hybrid samples and the optimal preservation of performances of initial cured plies of the virgin material into the recycled plate.

碳纤维复合材料热机械拆解与复合板压缩成型回收利用研究

通过对混合热成型复合材料板进行热机械拆卸和进一步压缩成型，提出了一种创新的热固性复合材料层压板回收工艺。由于热机械过程，从废弃层压板中提取出单个固化层。随后，通过在回收的复合材料层之间插入热塑性薄膜来进行再层压。通过压缩成型进行最终固结。为了证明这种新的回收技术的可行性，在烘箱中加热后，在手动辊弯机中对高压釜成型的碳纤维增强复合材料板进行了热机械拆卸。回收的固化层通过由低密度聚乙烯制成的交替热塑性夹层进行层压。混合层压板在220℃下固结�C和38.5巴的保持压力。原始板材和再生板材的弯曲试验结果表明，混合样品具有很好的团聚性，原始材料的初始固化层在再生板材中的性能得到了最佳保持。
