本文采用中心反对称±45°切槽单向铺层复合材料的圆板试件,获得了以实验方法求出系数F_(12)的满意结果。根据实验结果,对Norris、Tsai-Hill和Tsai-Wu理论的理论强度预测值与实验值进行比较,理论曲线与实验点符合较好。
In this paper, a circular plate specimen with anti-symmetrical ± 45 ° slotted unidirectional laminated composite material in the center was used to obtain the satisfactory result of experimentally calculating F_ (12). According to the experimental results, the predicted values of theoretical intensities of Norris, Tsai-Hill and Tsai-Wu are compared with the experimental values, and the theoretical curves are in good agreement with the experimental ones.
