摘要: 为了预测植入NiTi-玄武岩纤维混编纤维增强体的复合材料螺旋弹簧刚度，基于复合材料细观力学推导了混编织物复合材料单层板的等效剪切模量计算公式，建立了多层异种纤维混编织物增强复合材料螺旋弹簧的刚度预测模型。制作了多层NiTi丝和玄武岩纤维混编复合材料螺旋弹簧样件。试验刚度与理论计算刚度误差为2.7%，验证了提出的刚度预测模型的正确性，这对异种纤维增强复合材料结构刚度性能预测及工程化应用具有参考意义。
Abstract: In order to predict the stiffness of composite helical spring embedded with NiTi-basalt hybrid braided fiber reinforcement, the equivalent shear modulus calculation formula of orthogonal hy-brid braided composite plate was derived based on composite micromechanics, and the stiffness prediction model of composite helical spring reinforced by multi-layer dissimilar fiber hybrid braided was established. In addition, the multi-layer NiTi wire and basalt fiber hybrid braided composite helical spring specimen was made. The error between the experimental stiffness and the theoretical calculation stiffness is 2.7%, which verifies the correctness of the proposed stiffness prediction model. This work has reference significance for the stiffness performance prediction and engineering application of dissimilar fiber reinforced composite structures.
