We have developed a method for making carbon fibre profiles with a variable outer shape and a variable section.
The challenge
Constant-section profiles – pultruded or wound tubes – have the same stiffness along their whole length. But the load usually changes along the profile, so some of the material is not needed.
Result
A variable-section profile matches stiffness and mass to the load distribution along its length – more material where the bending moment is highest, less where it is low. We choose the process for the geometry and loads of the specific profile.
