Chopped strand mat (CSM) is a type of reinforcement material commonly used in the production of fibreglass composites. It consists of randomly orientated glass fibres that are cut into short strands and bonded together using an emulsion binder. CSM is one of the most widely used fibreglass reinforcement materials due to its versatility, ease of use, and relatively low cost.
