Composite Matrix Resin Classifications
Resin (or matrix) type
- Thermoset resins- those that undergo a chemical cross-linking reaction
- Epoxy: reaction of bisphenol A and epichlorohydrin
- Polyester: reaction of difunctional acid (or anhydride) and a difunctional alcohol (glycol)
- Polyurethane: reaction of alcohol and isocyanate
- Phenolic
- Silicone
- Melamine
- Thermoplastic resins- those that are formed under heat
- Polyamines (nylon) (short and long fibers)
- Polyesters (short and long fibers)
- Polypropylene (short, long fibers and continuous fibers)
- Other thermoplastic resins (short and long fibers)
