Scope

1.1 This document establishes a designation system of recycled carbon fibres, which may be used as the basis for specification.

1.2 This designation system is applicable to recycled carbon fibres used for polymer composites.

1.3 The types of recycled carbon fibres are differentiated by a designation system based on appropriate levels of the designatory properties.

a) tensile modulus of elasticity.

b) tensile strength.

NOTE: One to five designatory property(s) that differentiate recycled carbon fibre types from each other is (are) assigned.

1.4 It is not intended to imply that recycled carbon fibres having the same designation will give the same performance. This document does not provide engineering data or data on processing conditions that might be required to specify materials for a particular and/or method of processing.

1.5 In order to specify recycled carbon fibres for a particular application, additional requirements may be given in optional data block 5 (see 4.6)
