Infusion mesh is a type of material that is used in composite manufacturing to aid in the infusion process. It is typically made from a lightweight and flexible material, such as polypropylene , and is designed to act as a distribution medium for the resin during infusion.
During the infusion process, the infusion mesh is placed on top of the fiber reinforcement material, such as fiberglass or carbon fiber, and is then covered with a layer of perforated release film. The resin is then infused into the reinforcement material through the perforations in the release film, and is distributed evenly throughout the part by the infusion mesh.
The purpose of the infusion mesh is to ensure that the resin is evenly distributed throughout the part, reducing the risk of dry spots or resin-rich areas that can compromise the strength and durability of the finished product. The mesh also helps to prevent the reinforcement fibers from shifting or moving during the infusion process, which can also affect the final quality of the part.
Overall, infusion mesh is an important component in the composite manufacturing process, and is often used in conjunction with other materials, such as release film and peel ply, to create high-quality composite parts with excellent mechanical properties and durability.
