摘要/Abstract

摘要： 本文采用模压成型工艺,使用日本东丽公司T1100GC和M55J两种碳纤维预浸料制备了一系列单向混杂碳纤维复合材料(HCFRP)层合板,通过改变HCFRP的混杂比和铺层方式,研究了不同HCFRP在三点弯曲载荷作用下的力学性能,并使用光学显微镜观察HCFRP的破坏形貌,分析其失效模式。研究表明:单一T1100GC和单一M55J碳纤维复合材料均发生压缩破坏,B型混杂结构HCFRP则以中间层的剪切破坏为主,C型混杂结构HCFRP的破坏模式与混杂比有关。无论何种混杂结构的铺层方式,混杂比为47.1%的HCFRP均表现出最优的弯曲性能,其中以M55J碳纤维作为芯层的C型混杂HCFRP的弯曲强度最高,为2 052.7 MPa,其破坏模式表现为整体破坏;以T1100GC碳纤维作为芯层的C型混杂HCFRP的弯曲弹性模量最高,为310.5 GPa,其破坏模式表现为分层破坏。

Abstract: We have adopted T1100GC together with M55J carbon fibers as prepregs to fabricate a series of the unidirectional hybrid carbon fiber reinforced composite (HCFRP) laminates via molding method. By changing the hybrid ratio and layup methods of HCFRP, the bending properties of HCFRP have been investigated via three-point bending test, and optical microscope has been utilized to analyze their failure mode under bending loads. Our results indicate that both pristine T1100GC and M55J carbon fiber composites suffer from compression failure. The destroying of type B hybrid structures in HCFRP is mainly due to shearing failure in the middle layer, the failure mode of the HCFRP in type C is related to the hybrid ratio. HCFRP with the hybrid ratio of 47.1% exhibits the best bending properties regardless of layup methods. The flexural strength of HCFRP with M55J carbon fiber in the middle layer reaches the highest value of 2 052.7 MPa, and its failure mode is overall failure. In addition, the flexural elasticity modulus of HCFRP with T1100GC carbon fiber in the middle layer reaches the highest value of 310.5 GPa, and its failure mode is delamination failure.
