Truss structures made of carbon-fibre-reinforced polymer (CFRP) stand out for being lightweight and yet still offer excellent mechanical properties. At the Institute for Textile Technology (ITA) at RWTH Aachen University, a CFRP truss structure derived from biological origins was constructed. Using 3-D rotation weaving and a vacuum infusion method resulted in a glass sponge-like, or Euplectella structure.

Truss structures made of carbon-fibre-reinforced plastic (CFRP) have great potential for use in a wide range of lightweight products. They have also established themselves as a rival to conventional steel structures. The current hurdle to overcome for CFRP truss structures are what tend to be complex and thus expensive manufacturing methods [1].

The term truss refers to a material system comprising multiple interconnected rod members. The points at which the rods connect to each other are known as nodes. Trusses made of metal or wood may feature nodes in the form of joints, welds or...
