Connector for Composite Tubes

Abstract

Difficulties in joining tubular structural members made of composite materials are overcome by improved conectors. Connectors are made from same composite as structural shapes, eliminating stress and weight problems experienced with metal connectors. Composites allow joint strength to be optimized by properly choosing fiber orientation and fabric. Only two basic shapes are required to make 90 degrees and T-joints in plane. Used to assemble strong, lightweight, three-dimensional structures.
