Abstract

The objective of this research work is to analyze the behavior between fiberglass laminate under tensile tests, assembled under different humidity conditions. For which specimens were designed under the regime of the international standard ASTM D3039; which took an assembly process within a controlled environment; the design variables used were relative humidity and curing time. Subsequently, the traction-displacement behavior was checked under a uniaxial force, obtaining the maximum take-off force. In addition, Simpson numerical integration was applied to calculate elastic energy. Obtaining that the relative humidity and the days of curing influence the chemical and mechanical properties of the material. Se shows that the percentage of humidity recommended for assembling laminates in GRP is 66% since it has greater elastic energy and take-off force. Finally, it is concluded that to have a high resistance in the material at least 7 days of curing of the epoxy resin must be applied.

赤道地区湿度对 GFRP 容器制造的影响研究

这项研究工作的目的是分析在不同湿度条件下组装的玻璃纤维层压板在拉伸试验中的行为。为此，根据国际标准 ASTM D3039 设计了试样；试样在受控环境中进行组装；设计变量为相对湿度和固化时间。随后，在单轴力作用下检查了牵引-位移行为，获得了最大起飞力。此外，还应用辛普森数值积分计算弹性能量。结果表明，相对湿度和固化天数会影响材料的化学和机械性能。结果表明，在组装玻璃钢层压板时，建议使用 66% 的湿度，因为它具有更大的弹性能和起飞力。最后得出的结论是，要使材料具有较高的耐受性，环氧树脂必须至少固化 7 天。

期刊介绍： Defect and Diffusion Forum (formerly Part A of ''''Diffusion and Defect Data'''') is designed for publication of up-to-date scientific research and applied aspects in the area of formation and dissemination of defects in solid materials, including the phenomena of diffusion. In addition to the traditional topic of mass diffusion, the journal is open to papers from the area of heat transfer in solids, liquids and gases, materials and substances. All papers are peer-reviewed and edited. Members of Editorial Boards and Associate Editors are invited to submit papers for publication in “Defect and Diffusion Forum” . Authors retain the right to publish an extended and significantly updated version in another periodical.
