Abstract

A spar cap made from a plurality of separate composite rods bonded together in a mold to form the spar cap. A process for manufacturing a spar cap by bonding together separate composite rods in a mold, with a bonding agent to form the spar cap. A system for generating electricity, the system including a wind turbin installation configured to generate electricity, the wind turbin having a wind blade, the wind blade having a spar comprising spar caps, each spar cap having a plurality of plutruded composite rods bonded together in a mold to form each spar cap.
