Preparation of C/C composites by utilizing recycled plastics
In this paper,two typical representative of recycled plastics,ABS and SBS,were chosen as a new kind of impregnating agent to prepare C/C composites in order to provide a possible solution for the increasingly serious environmental problems such as recycling of plastic waste.The carbon fiber paper preforms were densified by impregnation,hot pressing and carbonization processes successively.The concentrations of raw material solutions(0.3 g/mL for ABS solution and 0.2 g/mL for SBS solution)and carbonization tempera-ture(430 ℃)were determined through viscosity and thermogravimetric tests.Based on the results of SEM,Raman spectroscopy and mechanical performance testing,it can be found that after carbonization,the mechanical properties of composites will deteriorate due to the change of matrix materials in content and structure.Compared with SBS,ABS is more suitable for the preparation of C/C compos-ites,and SBS is suitable for the preparation of CFRP composites.
