Recycled carbon fibre — Determination of tensile strength distribution from fibre bundle tensile test

Апстракт

This standard is for determination of tensile strength distribution of the recycled carbon fibre bundles from carbon fibre bundles tensile tests. It applies to continuous recycled carbon fibre bundles, from which specimens with a gauge length of 50 mm can be produced. Depending recycled process, the recycled carbon fibre can have rough surface and have friction force between fibres in the fibre bundle.
Fibre bundles made from recycled carbon fibre may contain internal fibre breakage, so the modulus of elasticity of the fibres should be known. The tensile modulus should be obtained from single fibre tensile tests or tensile tests of resin impregnated composite materials.
