Mechanical strength and chemical resistance
The specific requirements of the end product are decisive for the choice of the resin system. Basically, resin systems are used that have good adhesion to the fibers and have high mechanical strength and chemical resistance.
The most common resin systems used in filament winding are:
- Epoxy resin: Epoxy resins are one of the most common resin types for fiber composites. They offer high strength, rigidity and chemical resistance. However, epoxy resins can be brittle and are not as temperature resistant as other resin systems.
- Polyurethane resin: Polyurethane resins offer high impact resistance and are more flexible than other resin systems. However, they are more susceptible to moisture ingress and have lower chemical resistance.
- Polyester, polyvinylester and phenolic resins: are other resin systems that we work with and which can provide inherent benefits.
The choice of resin system depends on the end product requirements, including strength, stiffness, chemical resistance and temperature resistance.
AVANCO Composites can look back on decades of experience in the field of fiber winding. The majority of fiber composite products manufactured today and shipped to our customers are manufactured using the filament winding process. Like all other processes, the products manufactured in this way benefit from the high level of vertical integration and the possibility of customizing the products and adapting them to the application of our customers.
