Abstract

Abstract The article presents a method of modifying the strength properties of epoxy–glass composite by changing the percentage composition of the matrix by the addition of rubber recyclate. Taking into account environmental protection and economic conditions in the process of recycling and utilisation of waste, it is advisable to look for applications of non-degradable waste materials. Based on epoxy resin, a glass mat with a random direction of fibres and rubber recyclate, a test material with different percentage compositions was produced. Samples from the manufactured materials were subjected to a static tensile test on a ZwickRoell testing machine using the ARAMIS SRX measuring system. In addition, CT (computerized tomography) scans of the inside of the samples were made using a ZEISS METROTOM 6 Scout tomograph, and observations of the internal structures were made using a scanning electron microscope. The use of optical and microscopic techniques enabled the precise determination of strength parameters of the examined composites and the analysis of the behaviour of samples under load. The analysis of deformations over time in the examined samples showed a beneficial effect of the addition of rubber recyclate on the elastic properties of the examined composites.

3D光学技术在分析基体中添加橡胶再生胶对环氧-玻璃复合材料强度参数选择的影响中的应用

摘要本文提出了一种通过添加再生橡胶改变基体百分比组成来改变环氧玻璃复合材料强度性能的方法。考虑到废物回收利用过程中的环境保护和经济条件，建议寻找不可降解废物的应用。以环氧树脂为基础，以纤维和橡胶的随机方向为回收材料，制备了不同比例组成的试验材料。制造材料的样品在ZwickRoell试验机上使用ARAMIS SRX测量系统进行静态拉伸试验。此外，使用蔡司METROTOM 6 Scout断层扫描仪对样品内部进行CT(计算机断层扫描)扫描，并使用扫描电子显微镜对内部结构进行观察。使用光学和显微技术可以精确确定所检查的复合材料的强度参数，并分析样品在载荷下的行为。变形随时间的分析，在检查的样品表明，橡胶回收物的添加对所检查的复合材料的弹性性能有利的影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
