Tissue Mat

A tissue mat, often referred to as a tissue layer or simply tissue, is a type of non-woven reinforcement material used in composite manufacturing. It is typically made of chopped strand glass fibers or other fibers, which are bonded together with a resin. Tissue mats are designed to improve the surface finish, smoothness, and appearance of composite parts. They help reduce print-through, which is the visibility of the underlying fiber pattern, and enhance the aesthetics of the final product.

Tissue mats are commonly used in the production of fiberglass-reinforced composite parts, including boat hulls, automotive components, and various construction materials. They are applied during the lamination process and serve as a cosmetic layer that provides a smoother and more finished surface. Tissue mats can be used with a variety of resin systems, and they are valuable for achieving a high-quality surface finish in composite products.
