Abstract: A method for making a fiberglass truss has features that eliminate the need for a mold. The method includes first a step of tensioning a pair of spaced-apart filaments strips to define the chords for the truss. The chords are interconnected at several points along their lengths with a strip of filaments for defining triangular bracing or a web for the truss. Tension is applied to the strips to secure the chords and web in place. Then the chords and web are coated with resin. After hardening, the tension is removed. In one method, the chords are tensioned between two end walls of a container. The intersecting points of the web and chords are restrained against lateral movement by means of retaining devices mounted to two oppositely facing side walls. Triangular spacer elements define passageways for the chords and web. The container is filled with resin after the chords and web have been placed and tensioned. After impregnation, the container is drained. The completed truss may be removed after hardening.
