Can I use carbon fiber and aramid (Kevlar) reinforcement materials with polyester resin?
No, you should not because polyester resin chemical structure is not truly compatible with carbon and aramid. If you are planning to increase mechanical properties you should consider NCFs with polyester resin. If you need to use carbon or kevlar you can use with vinyl ester and/or epoxy resins for this purpose. You can find more information at the reinforcement materials section.
