Dynamic-Mechanical Properties of Polymer Composites with the Short and Long Glass Fibers

Abstract:

Nowadays the use of glass fibers in development of polymer composites creates a very interesting research area aiming to achieve multiple outputs to different applications. The use of thermoplastic composites reinforced with glass fibers in engineering applications like automotive industry has increased considerably in the last few decades. These composites combine high mechanical strength properties, reduced mass, easy processing and corrosion resistance. The shifting from metals to engineering composites pushes towards lightweighting benefits which results in improved fuel efficiency. This paper is focused on the assessment of polymer composites properties on the basis of polyamides (PA6.6) with the short (GF) and long glass fibres (LGF). The bulk characterization of all samples has been made by Dynamic Mechanical Analysis (DMA) depending on temperature, stress frequency and the weight percentage of reinforcement in matrix.
