Breather / Bleeder Fabric

Breather cloth, also known as breather fabric or bleeder, is a non-woven felt-like material used in a variety of vacuum bagging applications including vacuum bagging of wet-lay laminates and in debulking and curing of prepreg laminates.

When vacuum bagging wet-lay laminates, breather cloth serves both to provide an air path from the laminate to the vacuum connector and also to act as a bleeder or soaker, absorbing excess resin that is squeezed out of the laminate by the vacuum pressure. When debulking prepregs, breather is positioned on top of a perforated release film to help remove air from the laminate or when curing prepregs, breather is placed on top of unperforated release film over some or all of the laminate to maintain an airpath to the through-bag connector.

Our breather cloth is sold by the linear metre or in wholesale full rolls for maximum discount.
