Fibreglass Chopped Strand Mat

Fibreglass chopped strand mat, also known as CSM or simply fibreglass matting is the most established and ubiquitous reinforcement in composites. Chopped strand mat is a dry mat of randomly oriented glass strands, held together by some form of binder which breaks down as they are laminated. Chopped strand mat is low cost, easy to work with and extremely effective at creating strong, durable composite structures. Although superseded by woven glass or higher performance reinforcements such as carbon fibre in more demanding applications, chopped strand mat is still widely used in more traditional applications such as mould making, architectural mouldings, enclosures, flat roofs, traditional fibreglass canoes, boat hulls and much more.

Although concise, our limited range of chopped strand mats cover the vast majority of requirements.
