Abstract

Fiber reinforced polymer has been used in a broad scope of engineering equipment due to its outstanding advantages. This study investigated the effect of glass powder filler in the matrix modification of glass fiber reinforced polymer that can be further applied for hard structures. The composites were manufactured using a vacuum-assisted resin infusion method with 0, 2,5, 5, and 7,5 wt percentages of glass powder filler. The results have shown that adding glass powder filler in glass fiber reinforced polymer modifies the physical characteristics and enhances the mechanical properties compared to the neat composite. The failure mechanism obtained from the fracture surface investigation demonstrates bridging mechanisms formed effect of glass powder filler addition in the glass fiber reinforced polymer. The strengthening mechanism is formed to enhance the interfacial bonding between the fiber and the matrix. The results reveal the optimum filler addition percentage at 2,5 wt%. Adding 2,5 wt% glass powder filler enhances the flexural strength and interlaminar shear strength by 18,86% and 19,54%, respectively. The glass powder addition offers higher resistance to interlaminar damage. Additional glass powder with a higher weight percentage above the threshold induced microvoid and agglomeration phenomenon.

微玻璃粉填料改性gfrp基复合材料的高级性能及失效特性

纤维增强聚合物由于其突出的优点，在工程设备中得到了广泛的应用。研究了玻璃粉填料在玻璃纤维增强聚合物基体改性中的作用，为玻璃纤维增强聚合物在硬质结构中的进一步应用奠定了基础。复合材料采用真空辅助树脂灌注法，分别添加0、2、5、5和7.5 wt百分比的玻璃粉填料。结果表明，与纯复合材料相比，在玻璃纤维增强聚合物中加入玻璃粉填料可以改变其物理特性，提高其力学性能。从断裂面分析得到的破坏机理表明，玻璃粉填料在玻璃纤维增强聚合物中加入后形成了桥接机制。形成强化机制，增强纤维与基体之间的界面结合。结果表明，填料的最佳添加量为2.5 wt%。添加2.5 wt%的玻璃粉填料，其抗折强度和层间抗剪强度分别提高18.86%和19.54%。玻璃粉的加入提供了更高的抗层间损伤能力。添加重量百分比高于阈值的玻璃粉会引起微空洞和团聚现象。

期刊介绍： Journal of Engineering Research (JER) is a international, peer reviewed journal which publishes full length original research papers, reviews, case studies related to all areas of Engineering such as: Civil, Mechanical, Industrial, Electrical, Computer, Chemical, Petroleum, Aerospace, Architectural, Biomedical, Coastal, Environmental, Marine & Ocean, Metallurgical & Materials, software, Surveying, Systems and Manufacturing Engineering. In particular, JER focuses on innovative approaches and methods that contribute to solving the environmental and manufacturing problems, which exist primarily in the Arabian Gulf region and the Middle East countries. Kuwait University used to publish the Journal "Kuwait Journal of Science and Engineering" (ISSN: 1024-8684), which included Science and Engineering articles since 1974. In 2011 the decision was taken to split KJSE into two independent Journals - "Journal of Engineering Research "(JER) and "Kuwait Journal of Science" (KJS).
