受冲击损伤复合材料加筋壁板的抗剪切承载能力

Shear Carrying Capacity of Composite Material Stiffened Wall with Impact Damage

对两种不同铺层参数的复合材料加筋壁板结构进行了冲击损伤预制及剪切承载能力试验。讨论了冲击强度、铺层参数对加筋壁板剪切承载能力的影响。结果表明,随着冲击强度的增大,加筋壁板剪切承载能力逐渐减小,不同铺层参数的试样T2和P1在相同能量的冲击下,损伤面积虽然大致相同,试件P1比T2的破坏载荷高出19.1%。

The experimental study was performed on the impact damage and shear carrying capacity of composite material stiffened wall with different layer parameters.The influences of impact strength and layer parameters on the shear carrying capacity of the composite material stiffened wall were thus investigated.The results show that,in the case of different impact strength,higher impact strength leads to lower shear carrying capacity.Layer parameters have effects on shear carrying capacity,rather than the impact damage area.The destructive load of P1is 19.1% higher than T2.
