Mechanical behaviour of carbon and glass filament yarns under high temperatures for composite applications

Fibre composites made with high-performance fibres composed of carbon and glass are used in numerous technical applications due to their physical and chemical properties, which are valued for their high strength capabilities. Also in the construction field, textile fibres are gaining importance as reinforcements for concrete and are being coated to improve their bonding performance. Under thermal loads, these yarns show structural alterations in their mechanical properties. The following paper is concerned with experimental investigations of the strength and elasticity of commonly used textile fibres under high temperatures with the goal of specifying the materials’ parameters relative to thermal conditions.
