Abstract
In the recent years, composite polymers have been widely involved in a large scale of sensitive applications such as biomedical, remote healthcare, electronic devices, smart industry 4.0, and so on. This is due to their numerous advantages in terms of high precision measurement, mechanical and electrical strengths, and affordable cost, witnessed by various recent researches. Moreover, and to meet their environment installation conditions, polymers are usually reinforced by a protective layer, thoroughly produced by various resistant materials such as carbon fibers (CF). In that context, our present work aims to analyze and compare the temperature effect and the mechanical stress on the fiber-matrix interface damage for the three reinforced polymers: CF/poly ether ether keton (PEEK), CF/poly methyl methacrylate (PMMA), and CF/poly phenylene sulfide (PPS). The obtained results by a genetic approach and a non-linear acoustic technique obviously depict that for the three composite materials, and above 137°C, the interface damage increases very swiftly. In addition, the fiber-matrix interface adhesion of CF/PEEK shows better response compared to the other interfaces CF/PMMA and CF/PPS, this conclusion was confirmed by Aucher where he found in his study that the ductility of the resin and the strong fibre/matrix adhesion, especially in the case of CF/PEEK, is better compared to CF/PMMA and CF/PPS. Results obtained by our present study are intended to complete those already found in the field of the reinforced polymers designed for the aforementioned engineering applications.
期刊介绍:
Strength of Materials focuses on the strength of materials and structural components subjected to different types of force and thermal loadings, the limiting strength criteria of structures, and the theory of strength of structures. Consideration is given to actual operating conditions, problems of crack resistance and theories of failure, the theory of oscillations of real mechanical systems, and calculations of the stress-strain state of structural components.
