如今，纤维增强型材 (FRP) 在轻质结构、行人或车辆桥梁、塔楼和地面加固元件等应用中用作不同部分。玻璃钢型材的一些优点是重量轻、拉伸强度高、耐腐蚀、防水防潮。由于经济原因，玻璃纤维增强型材（GFRP）是 FRP 型材中的首选。在高温（如火灾）或冬季冰冻影响下使用这些材料的建筑物中，应了解强度损失。在这项研究中，采用拉挤成型方法生产的尺寸为 74 x 74 x 4 毫米的 GFRP 盒型材的拉伸和压缩样品在不同温度下进行了测试。在严寒和高温下，在 13 个不同温度下对样品进行拉伸和压缩测试：50、25、10、0、+10、+25、+50、+75、+100、+125、+150、+175、+200，在拉伸和压缩应力的影响下，确定了 GFRP 型材的强度损失。 (C) 2016 Elsevier Ltd. 保留所有权利。
Nowadays, Fiber Reinforced Profiles (FRP) are utilized as different sections in applications such as lightweight structures, pedestrian or vehicular bridges, towers, and ground reinforcement elements. Some of the advantages of FRP profiles are light weight, high tensile strength, corrosion resistance and performance against water and moisture. Glass Fiber Reinforced Profiles (GFRP) are preferred among FRP profiles due to economic reasons. In buildings where these materials are used at high temperatures such as fire or under the influence of freezing during the winter months, the loss of strength should be known.In this study, tensile and compressive samples from GFRP box profiles measuring 74 x 74 x 4 mm produced with the pultrusion method were tested at different temperatures. Samples were tested with tensile and compressive tests at 13 different temperatures: 50, 25, 10, 0, +10, +25, +50, +75, +100, +125, +150, +175, +200 in severe cold and high temperatures under the influence of both tensile and compressive stress and losses of strength for GFRP profiles were determined.
