超薄单层碳纤维增强复合材料板拉伸和压缩失效行为研究
Study on tensile and compression failure behavior of ultra-thin-ply carbon fiber reinforced composite panel
摘要
Abstract
The thinning of carbon fiber reinforced composites has further improved their mechanical properties and design space.In order to investigate the basic mechanical properties and failure mechanism of ultra-thin-ply carbon fiber reinforced composites,unidirectional composites with four ply thicknesses of 24 μm,55 μm,75 μm and 100 μm were prepared and subjected to longitudinal tensile,transverse tensile,longitudinal compressive,and transverse compressive experiments.Analysis was conducted on the influence of ply thickness on the modulus and strength of carbon fiber reinforced composites,revealing the failure modes and mechanisms of unidirectional carbon fiber reinforced composites with different ply thicknesses.The results indicate that the influence of ply thickness on the longitudinal tensile strength,transverse tensile strength,longitudinal compressive modulus and transverse com-pressive modulus of carbon fiber reinforced composites is not monotonic.Proper ply thickness can enable the com-posite to exhibit the best mechanical properties.Furthermore,the thickness of the ply also has a significant impact on the failure mode of the unidirectional carbon fiber reinforced composites,mainly manifested in the degree of transverse splitting,fiber fracture,delamination,and crack initiation and propagation mode.关键词
