An Endurance Test of Composite Panels

Abstract:

In this paper possibilities of freight wagons modernization using new composite materials was presented. This work was carried out under the project number PBS2/A6/17/2013 agreement implemented under the Applied Research Program, founded by the National Centre for Research and Development. All of this activities are done as consortium consists of the scientific entity – the Institute of Engineering Processes Automation and Integrated Manufacturing Systems of the Silesian University of Technology and DB Schenker Rail Poland SA and Germaz. The purpose of this article is analyse the work strength of the connection sheet metal and composite glass-epoxy with multi-point pressure. To estimate the strength of strain-gauge methods were used. The study was conducted on a stand equipped with 4 pneumatic actuators and the PLC. During the tests the same steal plate, then on a plate with mounted rivets and connection steal and composite panel were checked. Some aspects have already been presented in previous publications of the authors. This article is an extension of the previous publications with new knowledge. To determine the changes in the samples strain gauges was used. In the article original program written to the PLC in order to automatically generate pressure on the tested composites was presented. A composite material is a material having a heterogeneous structure composed of two or more components with different properties. structural components most commonly used are fibers such as glass fibers, carbon fibers and Kevlar. Currently, composites are widely used, among others, in construction, aviation, in transprcie, automotive and machinery manufacturing. In this paper research methods for detection of laminate panels damage were presented. Aspect of continuous monitoring of the technical state of the laminate is very important. As part of the work method of endurance test panels made of composite by strain gauge will be presented. In paper machine designed to periodically generate extortion will be also presented. At the Faculty of Mechanical Engineering Technical University of Silesia are conducted research on the analysis and synthesis of mechanical systems and mechatronics concern both theoretical considerations [10,11] how practical industrial tasks Recent works undertaken relate to research the properties of composite materials [1-4, 12-17] as components and assemblies railway wagons [5,8,11]. Some of the work is conducted in collaboration with other research centers [5-9].
