Turbine Engine Composite Preforms: Design of MAGNAWEAVE Loom for 3-D Braiding Net Shapes
Abstract
Three dimensional braiding technology should fabricate integrally braided preforms for turbine engine parts. Using MAGNASWIRL technology, a circular 3D braiding machine design was proposed. Design requirements were defined in terms of anticipated performance requirements for gas turbine rotors. Preliminary designs were generated for a 30-ring, 360 slot/ring MAGNASWIRL machine, capable of preform fabrication for (1) test discs, (2) 2- or 4-bladed discs, (3) 36 bladed discs. Silicon carbides (continuous filament) were the fibers of design. Loom loadings were developed to provide continuous and constant fiber volume; machine motion sequences were developed for integrally fabricating body and turbine blades.
