A mixture of resin and ingredients such as catalyst, initiator, diluents, and so forth, required for the intended processing and final product. A process whereby catalyzed resin is transferred or injected into an enclosed mold in which the fiberglass reinforcement has been placed. See also resin pocket. Index resin-starved area Localized area of insufficient resin, usually identified by low gloss, dry spots, or fiber showing on the surface. It usually has a softening or melting range and fractures conchoidally.
Most resins are polymers.
See also polymer. The ability of a material to resist passage of electrical current either through its bulk or on a surface. Index reverse helical winding In filament winding, as the fiber delivery arm traverses one circuit, a continuous helix is laid down, reversing direction at the polar ends. In contrast to biaxial, compact, or sequential winding. The fibers cross each other at definite equators, the number depending on the helix.
