MECHANICAL PROPERTIES OF CARBON FIBER REINFORCED PLASTIC STRUCTURES WITH DIFFERENT FORMING PROCESS
摘要
Abstract
Two carbon fiber reinforced plastic (CFRP) structures were prepared by hand lay-up process,vacuum bag pressure process and compression molding process.The effects of forming process on the mechanical properties and forming quality of CFRP structures were investigated based on tests and cross-section morphology observation.For the application of CFRP in the electric vehicle,two typical kinds of structures,laminated plates and double-cap tubes,were designed and prepared by different process.The tensile and three point bending tests were carried out,and the mechanical properties,surface qualities,microstructures and failure modes of structures were compared.The results indicate that the composite structures made by compression molding process have better quality with fewer bubbles and smaller porosity.The tensile strength of CFRP laminated plate made by compression molding process is about 14.39％ higher than hand lay-up laminated plate.The bending strength of tubes is twice of hand lay-up tubes,and is 47.58％ higher than vacuum bag pressure tubes.It is concluded that the CFRP structures prepared via the compressing molding process have higher mechanical properties and better consistency than the other process,it is more suitable for the application on the electric vehicle and other lightweight structures.关键词
