GRP Pipe Material
Glass fiber reinforced plastics (GRP) are a composite consisting of at least two different materials. The benefits of each material are united to achieve an overall effect.
A binder or matrix and reinforcing material is commonly used to combine the physically differing raw materials. Their molecules do not bond but they form a composite by joining their boundary layers. What is important is that the constituents are compatible in terms of properties and processing. This technology originated in the aviation and marine industry where particularly light high-performance materials are required.
Pipes made of centrifugally cast glassfiber reinforced plastics (GRP) consist of a combination of thermosetting plastics such as for example unsaturated polyester or vinyl ester resins, chopped glass fibers and reinforcing agents. The standard wall structure ensures that the individual materials bring their special features to bear in the finished composite. Further details can be found under Centrifugal Casting Technology.
It would be difficult to imagine today's life without glass-reinforced plastics. They are used, for example, in the following industries:
- Automotive industry (bumpers, bodies, etc.)
- Aerospace industry (tail units, panels, etc.)
- Water and wastewater engineering (pipes, tanks, manholes)
- Chemical industry
- Wind turbines
- Electrical industry
- Sports equipment industry, etc.
