A Redesigned eVTOL Propeller Gained 80% More Stiffness and Cut Production Time by 30%: Using Fabric, Not Prepreg Tape

A 2025 CEAS Aeronautical Journal study rebuilt an eVTOL propeller around stitch-free tailored non-crimp fabrics and a design tool that puts manufacturing cost in the loop — gaining 97% bending and 83% torsional stiffness while cutting labour and time by roughly 30%. Our summary of what the redesign actually bought, and where it connects to automated fibre placement.
