摘要
Abstract
To reduce the weight of the vehicle body,a lightweight design was applied to the metal battery pack lid using glass fiber composite materials.The process involved utilizing black flame-retardant glass fiber grid cloth prepreg and DP590 steel plate integrated molding technology.Through experiments and microscopic analysis,acid-base cleaning,sandblasting,and electrophoretic coating were identified as the optimal modifications for the steel plate.Nine orthogonal experiments were designed for glass fiber-steel plate reinforced composite materials with a to-tal thickness of 1.5 mm.Simulation analysis and experimental testing were conducted for the nine different combina-tions,focusing on bending and tensile simulations as well as testing experiments.The mechanical properties of the composite materials were obtained,with a maximum relative deviation of 1.49%between simulation and testing re-sults,indicating the reliability of the simulation.Through extreme difference analysis of the orthogonal experiment results,the optimal process parameter combination was determined to achieve the best bonding strength.The recom-mended parameters include a mold temperature of 150℃,molding pressure of 12 MPa,steel plate thickness of 0.8 mm,and a 1+1 steel plate composite structure.The tested samples met design requirements for peel strength,water absorption,flame resistance,heat deformation temperature,and voltage resistance.The weight reduction achieved was 39.4%,meeting the requirements for lightweight design.关键词
