However, the key challenge lies in creating effective joint structures able to connect together multiple WrapToR beams of different sizes and orientations. This paper addresses this challenge by presenting a modified WrapToR winding process which enables three-dimensional winding of arbitrary space frame joints, with an initial focus here on a proof of concept coaxial joint. This includes the design and manufacturing of a coaxial joint demonstrator and the development of a finite element analysis tool to predict its mechanical performance.
