摘要
碳纤维复合材料(CFRP)具有高刚度、高强度等优势,是进行轻量化结构设计的先进新型材料.铺层优化设计是CFRP制件结构设计的重要内容之一.基于ABAQUS对CFRP耐压支撑管铺层结构进行优化.确立以[(90°/±20°)5/90°/(±20°)9/90°/(±20°/90°)5]为最终铺层方案.采用干法缠绕成型工艺制备CFRP耐压支撑管,以有限元法和试验法对方案进行验证.结果表明:模拟分析CFRP耐压支撑管的抗压强度为817.4 MPa,抗压模量为167.7 GPa,对应的强度安全系数为1.84,模量安全系数为1.86.CFRP耐压支撑管的平均抗压强度为683.85 MPa,平均抗压模量为137.9 GPa,对应的强度安全系数为1.54,模量安全系数为1.53,均能够满足技术性能指标要求.
Abstract
Carbon fiber-reinforced polymers(CFRP),with their high stiffness and strength,are an advanced new material for lightweight structural design.Ply optimization design is one of the important aspects of the structural design of CFRP components.The layer structure of the CFRP pressure-resistant support pipe is optimized based on ABAQUS.[(90°/±20°)5/90°/(±20°)9/90°/(±20°/90°)5]was determined as the final layering scheme.The CFRP pressure-resistant support pipe was prepared by dry winding process,and the scheme was verified by finite element method and experimental method.The results show that the compressive strength of the CFRP pressure-resistant support pipe is 817.4 MPa,the compressive modulus is 167.7 GPa,the corresponding strength safety factor is 1.84,and the modulus safety factor is 1.86.The average compressive strength of the CFRP pressure-resistant support pipe is 683.85 MPa,the average compressive modulus is 137.9 GPa,the corresponding strength safety factor is 1.54,and the modulus safety factor is 1.53,which can meet the requirements of technical performance indicators.
