90° Fibers maximize crushing stiffness and generally assist in overall tube strength.

45° Fibers maximize torsional stiffness.

Manufacture Process

Roll wrapped carbon fiber tubes are manufactured using multiple layers of carbon fiber prepreg materials. 

• 1. Wrapped onto a mandrel in multiple layers and angles

• 2. Externally pressurized with transparant PP tape

• 3. Heat cured to solidify

• 4. After curing, the solid composite is demoulded from the mandrel as a tube
