MATERIAL PREPARATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide automated bias-ply material preparation device and process.SOLUTION: A material preparation device 100 includes a bias-ply assembly 105, a feedstock assembly 103 and an application head 130. The bias-ply assembly 105 is configured to pass a bias-ply backing material 146 along a first path. The feedstock assembly 103 is configured to pass a feedstock along a second path that crosses the first path at a select angle. The feedstock includes resin pre-impregnated fiber reinforced material (prepreg) having the fibers at a first orientation relative to an edge of the feedstock. The application head 130 is configured to transfer the pre-preg from the feedstock to the bias-ply backing material 146 at a location where the first path crosses the second path to form a bias-ply 158 with the fibers of the pre-preg having a second different orientation relative to an edge of the formed bias-ply 158.
