What is a composite reinforcement?


A composite reinforcement is a material that is used to reinforce the mechanical properties of a base material. Fiberglass reinforcements are the most common due to their affordable cost as well as their relative strength and lightness, which makes them perfectly suitable for the manufacture and repair of solid structures. They are used in the automotive, aeronautical, shipbuilding, and building industries.


There are two types of fiberglass reinforcement commonly used: woven fiber reinforcement and mat nonwoven fiber reinforcement. Woven fiber reinforcements are manufactured by weaving fiberglass threads in chains and frames to create a roving (taffeta/weave), sergeant, or satin structure. These reinforcements are generally used with an epoxy, polyester, or vinyl ester resin matrix in stratification or infusion processes. Each of these types of weaving has advantages and disadvantages in terms of mechanical properties and cost.
