随着碳纤维增强复合材料(Carbon Fiber Reinforced Polymer/Plastic,CFRP)及其制造工艺的发展,可设计性较强的CFRP产品用来替代金属结构以实现轻量化设计,受到更多设计者的关注.以CFRP回转壳体为研究对象,基于ABAQUS建立CFRP回转壳体有限元分析模型,探讨缠绕角度对结构力学性能的影响,并设计了两种纤维缠绕方案.通过拉伸性能分析、压缩性能分析以及加速度过载性能分析对设计结构进行强度校核,最终确定以[90°/(90°/±20°/±45°)2/90°/±20°/90°/±45°/90°]s为成型方案.采用干法缠绕工艺对该方案的CFRP回转壳体进行制作,通过试验法进行对比验证.结果表明:纤维缠绕角度为0 时,CFRP回转壳体抗压性能最优;抗拉强度/模量偏差率为24.23%/18.71%,抗压强度/模量偏差率为9.56%/18.62%,过载强度模量偏差率为3.22%/2.72%,验证了有限元模型具备一定的准确性;根据安全系数计算可知,该纤维缠绕设计方案能够达到技术性能指标要求.
Fiber Winding Angle Design and Experimental Verification of Composite Rotary Shell
With the development of carbon fiber reinforced polymer/plastic(CFRP)and its manufacturing process,CFRP products with strong designability have been used to replace metal structures to achieve lightweight design,which has attracted more attention.In this study,the CFRP rotary shell is taken as the research object.The finite element analysis model of CFRP rotary shell is established based on ABAQUS.The influence of wind-ing angle on the mechanical properties of the structure is discussed,and two kinds of fiber winding schemes are designed.The strength of the designed structure was checked by tensile performance analysis,compression per-formance analysis and acceleration overload performance analysis.Finally,[90°/(90°/±20°/±45°)2/90°/±20°/90°/±45°/90°]s was determined as the forming scheme.The CFRP rotary shell of this scheme was fabrica-ted by dry winding process.The design scheme is compared and verified by the test method.The results show that the compressive performance of CFRP rotary shell is the best when the fiber winding angle is 0;The deviation rate of tensile strength/modulus is 24.23%/18.71%,the deviation rate of compressive strength/modulus is 9.56%/18.62%,and the deviation rate of overload strength modulus is 3.22%/2.72%,which verifies that the finite ele-ment model has certain accuracy.According to the calculation of safety factor,the fiber winding design scheme can meet the requirements of technical performance indicators.
