ABSTRACT:
Fiber-reinforced resin pipes and pipe fittings have a structural pipe wall formed from helically wound reinforcing fiber that is bonded together with a polymer resin. An intermediate layer is disposed around the structural pipe wall, and a fiber-reinforced layer is disposed around the intermediate layer. The intermediate layer is formed from material selected from the group consisting of impact attenuating and impact absorbing materials. The fiber-reinforced resin layer comprises layers of helically wound reinforcing fiber bonded together with a polymer resin. The materials selected to form the fiber-reinforced resin layer can be the same or different from that used to form the structural pipe wall. The pipe may comprise a single intermediate and fiber-reinforced layer disposed around the structural pipe wall, or may comprise an impact resistant jacket disposed around the structural pipe wall, wherein the jacket is made up of alternating intermediate and fiber-reinforced resin layers. Fiber-reinforced resin pipes, constructed according to principles of this invention, have improved impact resistance when compared to conventionally constructed fiber-reinforced resin pipes.
