Summary:对碳纤维-玄武岩纤维混杂增强树脂基复合材料最优混杂比范围进行研究。以碳纤维与玄武岩纤维平纹织物为增强体,制备9种具有不同混杂比的混杂纤维复合材料（Hybrid Fiber Reinforced Polymer,HFRP）试样,并进行拉伸实验。依据平纹织物结构特点,计算得出平纹织物单胞性能参数,在ANSYS中,以SHELL181壳单元体建立HFRP有限元模型。该模型对试样刚度的模拟值与实验值近似。分析模型受力时的应力云图发现,存在将HFRP破坏形式分为一次破坏与二次破坏的临界混杂比。有限元模拟研究树脂含量为45%时,不同混杂比的HFRP刚度、强度和拉伸极限应变。当混杂比为60%时,可保证HFRP强度无折减的情况下,较玄武岩复合材料（Basalt Fiber Reinforced Polymer,BFRP）刚度提高93.4%,较碳纤维复合材料（Carbon Fiber Reinforced Polymer,CFRP）拉伸极限应变提高11.3%。

The optimum hybrid ratio range of carbon/basalt hybrid fiber reinforced resin composites was studied. Hybrid fiber compos-ites with nine different hybrid ratios were prepared before tensile test. According to the structural features of plain weave, the unit cell,s performance parameters were calculated. Finite element model was established by using SHELL181 in ANSYS. The simulated values of the sample stiffness in the model were approximately similar to the experimental ones. The stress nephogram shows that there is a criti-cal hybrid ratio which divides the failure mechanism of HFRP into single failure state and multiple failure state. The tensile modulus, strength and limit tensile strain of HFRP with 45% resin are simulated by finite element method. The result shows that the tensile mod-ulus of HFRP with 60% hybrid ratio increases by 93.4% compared with basalt fiber composites （BFRP） , and the limit tensile strain increa
