Effect of Heat Curing Temperature for CFRP Fabricated by Electrodeposition Resin Molding Method

Abstract

The new electrodeposition resin molding (EDRM) technique is regarded as a rapid and effective way to produce composite materials. In this study, the composite preparation was done using this technique. The heat curing stage is one of the key steps in this process. The optimization of the many conditions was required because it is a new method. The major objective of this study is to establish the ideal heat curing temperature and time for producing CFRP of the highest grade. In this investigation, two alternative temperature profiles were used. One measured 215°C, the other 230°C. Three different heat curing times—4 hours, 6 hours, and 8 hours—were used for each profile. Static and dynamic characteristics of the prepared CFRP were assessed to determine the impact of these heat curing temperatures and treatment times. Fourpoint bending tests were done for the static properties, and vibration tests were done for the dynamic qualities to determine the natural frequency and damping. Even though the various heat treatment methods had little impact on vibration characteristics, they had a big impact on bending qualities. The specimens that were held in the oven for 8 hours at 215°C to produce the highest bending strength, however at 230°C, the maximum bending strength was found when it was kept for 6 hours in the oven for treatment.
