TS ISO 8604

TS ISO 8604 is a terminology standard that explains the terms and symbols used for designating crosslinkable prepregs. For this product family, the standard’s value lies in giving manufacturers, users and technical documentation a common language for identification, production and use of prepregs, rather than defining a test method or product specification.

What a prepreg means in composite materials

In general technical terms, a prepreg is a reinforcement material that has been pre-impregnated with resin. In crosslinkable systems, the resin later cures and forms a network structure, which is central to the final properties of the composite. Clear terminology matters because prepreg-based materials involve several linked concepts: reinforcement, resin content, processing state and the intended curing route.

Terminology and symbols used for designation

According to the title and scope, this standard covers the terms and symbols used in the designation, manufacture and use of crosslinkable prepregs. In practical engineering communication, such vocabulary helps keep product descriptions, ordering information, technical files and manufacturing discussions consistent across the supply chain. It is especially useful where composite materials are identified by how they are made and how they will be processed later.
