Matched-die Tooling and Fabrication of Composite C-section Spar Prototype
Main Article Content
Abstract
Composite materials are having high strength and are used in the aerospace and marine industry. Most of the wings and wind turbine blades have an aerofoil box structure with more internal components such as ribs, spars and stringers (stiffeners) for strength and stability compliance. So many industries prefer the I section, T section and C section composite spars. Different tooling concepts and different processes for the fabrication of spar have been discussed. The paper focuses on a matched-die tooling concept and fabrication of the C-section composite spar. After designing the tooling concepts, the C-section spar prototype is fabricated using the male tool and female tool, quality and inspection are done for the product made.
