ISO 19374:2026

This document establishes a designation system of recycled carbon fibres, which can be used as the basis for specification. This designation system is applicable to recycled carbon fibres used for polymer composites. The types of recycled carbon fibres are differentiated by a designation system based on appropriate levels of the designatory properties: tensile modulus of elasticity. tensile strength. NOTE One to five designatory property(s) that differentiate recycled carbon fibre types from each other is (are) assigned.
