碳纤维织物在室内空间中的设计与性能研究

Research on the Design and Performance of Carbon Fiber Fabric in Indoor Space

为了将现代碳纤维织物应用于室内空间设计,对比分析了编织角度和纤维含量对单向编织对称铺层复合材料和二维编织对称铺层复合材料拉伸强度、拉伸模量和破坏模式的影响。结果表明,单2试样的最内层和最外层角度的差值高于单1和单3试样,造成纤维体积分数明显减小,拉伸强度明显降低;二维2试样的最内层编织角相较于二维1和二维3分别增加5°和3°,最内层编织角都相比增加了3º,纤维体积分数分别减小3.02%和2.87%,拉伸强度分别减小30.22MPa和7.7MPa;编织角和纤维含量都会对单向编织对称铺层复合材料和二维编织对称铺层复合材料的拉伸强度和拉伸模量造成显著影响。相较于单向编织对称铺层复合材料,二维编织对称铺层复合材料中的裂纹或者裂缝变得杂乱无章,但破坏最严重的区域都出现在外侧,而1/2宽度处的破坏相对较轻。

In order to apply modern carbon fiber fabric to interior space design,the effects of braiding angle and fiber content on the tensile strength,tensile modulus and failure mode of unidirectional braided symmetrical ply composites and two-dimensional braided symmetrical ply composites were compared and analyzed.The results show that the difference of the angle between the inner layer and the outer layer of the single 2 specimen is higher than that of the single 1 and the single 3 specimens,resulting in a significant decrease in fiber volume fraction and tensile strength;the braiding angle of the inner layer of the two-dimensional 2 specimen increases by 5°and 3°,respectively,compared with the two-dimensional 1 and two-dimensional 3,while the braiding angle of the inner layer increases by 3°,the volume fraction of the fibers decreases by 3.02%and 2.87%tensile strength decreases by 30.22 MPa and 7.7 MPa,respectively.Both braiding angle and fiber content have significant effects on the tensile strength and modulus of unidirectional braided symmetrical laminated composites and two-dimensional braided symmetrical laminated composites.Compared with unidirectional braided symmetrical laminated composites,cracks in two-dimensional braided symmetrical laminated composites become disordered,but the most serious damage areas appear outside,while the damage at 1/2 width is relatively light.
