RAW MATERIALS FOR FRP PRODUCT MANUFACTURING
It is the absolute mainstay of fiberglass (FRP) and the entire composite materials industry.
Glass fiber is a high-performance, widely used inorganic non-metallic material, often used as a reinforcing material embedded in a resin matrix to form strong composite materials.
Products Description
It is the absolute mainstay of fiberglass (FRP) and the entire composite materials industry.
Glass fiber is a high-performance, widely used inorganic non-metallic material, often used as a reinforcing material embedded in a resin matrix to form strong composite materials.
Common product forms:
| form | describe | Features and Applications |
| Untwisted roving | A yarn bundle formed by twisting parallel raw silk bundles together. | winding, pultrusion, and spraying processes. Provides primary strength. |
| Short-cut raw fibers | It is made by cutting untwisted rovings into short sections. | Compression molding (BMC/SMC) and spraying processes provide isotropic properties. |
| Surface felt | It is made up of randomly laid-out monofilaments. | an inner lining layer for products , a resin-rich layer that provides corrosion and leak protection while concealing fiber texture. |
| chopped strand mat | It is made of chopped raw fibers randomly laid out and fixed with an adhesive. | hand lay-up and vacuum injection processes, offering excellent conformability and high interlayer strength. |
| Knitted felt | Short fibers are sewn together using a loop structure. | It has higher strength than chopped strand mat, and resin penetrates quickly, making it suitable for hand lay-up and LRTM. |
| Fabric (grid fabric/axial fabric) | It is woven from yarn. | It has high strength and strong layup design flexibility , and is used for hand layup and vacuum injection, providing high strength in a specific direction. |
