Abstract
An end effector for needling a fibrous preform includes a body (or head), a plurality of articulating presser feet mounted to the body and moveable with respect to the body, and a plurality of articulating needles mounted to the body and moveable with respect to the body. The needles may be configured to move between an extended position and a retracted position. The presser feet may be configured to move between an extended position and a retracted position. The end effector presser feet may conform to complex geometries of a fibrous preform. The end effector may control needling depth, needling density, applied tension and/or pressure on the fibrous preform, and needle angle.
