Finite element analysis on heat distribution ratio during grinding CFRP

Carbon fiber reinforced plastics possess high specific modulus, specific strength and specific stiffness, which shows great application prospects in the field of aeronautics and astronautics. When grinding carbon fiber reinforced resin composites composed of carbon fibers and resins, the grinding temperature may exceed the glass transition temperature of the resin, leading to resin burn-out and other defects. In order to study this problem, the semi-artificial thermocouple of carbon fiber composite and constantan wire is used to measure the in-situ temperature in grinding process, and the heat distribution between workpiece and others is studied by combining experiment with finite element simulation. It is found that the heat imported to workpiece is 2.0% to 3.5% of the total heat during grinding process.
