AI Technical Summary
Current manufacturing methods for composite driveshafts are limited in producing geometries with sharp angles or small corner radii, which are necessary for accommodating bending and misalignment, due to fabrication limitations in automated fiber placement technology.
A method involving automated fiber placement followed by a post-treatment process to compress and modify the shape of preliminary composite driveshafts, allowing for the creation of flexible composite driveshafts with sharp angles or small corner radii between flexible elements, using loads and heat to achieve desired geometries not possible in direct one-step AFP-based lay-up.
Enables the production of driveshafts with increased axial and bending flexibility, accommodating complex load requirements and misalignment, while reducing fiber breakage and improving manufacturing efficiency.
