Abstract

In this study, Carbon, Glass, and Aramid fiber reinforced composite and their hybridized forms were fabricated using five different stacking sequences of the fabrics. Using the Vacuum Assisted Resin Transfer Molding (VARTM) procedure, epoxy resin was injected into these fabrics and allowed to cure at room temperature. From these five stacking sequences, a standard specimen with four different orientations viz. 0/90°, 15/75°, 30/60°, 45/-45° orientations were obtained using the Abrasive Water Jet Machining(AWJM) Process. The influence of stacking order and fiber orientation on tensile and flexural properties of composite was investigated. From the result of tensile testing, the highest and lowest tensile strength values were observed for neat carbon fiber reinforced composite at 0/90° orientation and at 45/-45° orientation respectively. The highest flexural strength was achieved in a hybrid combination of two layers of carbon, glass and aramid fabric for 0/90° whereas the lowest flexural strength was found in glass reinforced composite for the 45/-45° orientation.

叠层顺序和纤维取向对VARTM工艺制备的纤维增强复合材料拉伸和弯曲强度的影响

在本研究中，碳、玻璃和芳纶纤维增强复合材料及其杂化形式通过织物的五种不同的堆叠顺序制备。使用真空辅助树脂传递成型(VARTM)工艺，将环氧树脂注入这些织物中，并在室温下固化。利用磨料水射流加工(AWJM)工艺，从这五种堆叠顺序中获得了四种不同取向(0/90°、15/75°、30/60°、45/-45°)的标准试样。研究了层序和纤维取向对复合材料拉伸和弯曲性能的影响。拉伸试验结果表明，纯碳纤维增强复合材料的拉伸强度在0/90°取向和45/-45°取向时最高和最低。在0/90°方向上，两层碳、玻璃和芳纶织物的混合组合具有最高的抗弯强度，而在45/-45°方向上，玻璃增强复合材料的抗弯强度最低。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
