This study aims to improve the impact resistance of composite materials through hybrid structures. The effects of parameters such as hybrid fiber ratios and plying modes on the material were investigated. The results showed that the specimen with a fiber content of 15 g/m2 had the highest peak load and absorption energy. Specimens with different plying modes had the most significant effect on the maximum load.
To understand the hybrid fiber enhanced impact-resistance performance of composite laminates. In particular, the effects of different parameters, such as hybrid fiber ratios and plying modes, were investigated. The effects of UHMWPE short fibers (UHMWPESFs) fiber content and ply angle changes on the impact resistance of Carbon fiber/ultra-high molecular weight polyethylene short fiber hybrid composite (CUFHRP) laminates were investigated in this article. The impact resistance of the CUFHRP laminate was tested by the drop weight test and residual strength test after impact. The results indicated that the peak load and absorption energy of the specimen with a fiber content of 15 g/m2 were the highest, reaching 6.543 kN and 16.51 J, respectively. Specimens with different ply modes of [0/-45/45/90]2s showed the most obvious effect on the maximum load. Its maximum load was 28.93% higher than that of the original sample. The critical damage threshold load of composite laminates is improved, and the impact resistance is strengthened.HighlightsStudy to improve the impact resistance of the composite on the basis of the hybrid structure.Report the optimal parameters of the effects on the impact resistance of the composite, such as: hybrid fiber ratios and plying modes.Reveal the fundamental failure mode of hybrid structure composite laminates under low-velocity impact.
