Mechanical Design of Intersection Points of Tailored Fiber Placement Made Carbon Fiber Reinforced Plastic Truss-Like Structures

Abstract:

The presented study emphasizes a favored design for carbon fiber reinforced plastic fiber patterns at intersection points of truss-like structures made with the Tailored Fiber Placement technology. Three different pattern types have been experimentally and numerically analyzed. A straight fiber crossing is the most simple design, but it cannot compete against a fanned out fiber pattern regarding structural stiffness, where fiber spacing increases with increasing crossing distance. A pattern design, where belt and web fiber paths merge, is the most preferred design due to a minimum of material waste, however it exhibits lower stiffness compared to the fanned out pattern.
