Question: is frp the same as fiberglass?
Answer: Fibreglass is the term used in British English, Fiberglass expresses the same in US English. FRP stands for Fiber (fibre) Reinforced Polymeres – and again means the same thing. GFK which just is the abbreviation of the German term for it, Glasfaserverstärkter Kunststoff, often informally used, too.
