Abstract: Systems and methods are provided for applying lengthwise curvature to composite parts. One embodiment is a method that includes fabricating a preform for a curved pultruded gap filler by continuously: heating fiber reinforced material to a sticking point temperature for a constituent material within the fiber reinforced material, and feeding the fiber reinforced material through a die that exhibits a curvature through which the fiber reinforced material travels while the fiber reinforced material is heated to the sticking point temperature, the die forming the fiber reinforced material into a preform for a gap filler. Fabricating the curved pultruded preform further includes varying path lengths of fibers within the preform as the preform passes through the die, and pulling the preform out of the die.

Abstract: An end effector for a robotic sanding system includes a sanding head including a sander configured to sand a surface of a workpiece. A motor is operatively coupled to the sander. The motor is configured to rotate the sander to sand the surface of the workpiece. The motor includes a first central longitudinal axis. A coupler is configured to removably secure the end effector to an attachment interface of an arm of the robotic sanding system. The coupler includes a second central longitudinal axis. The first central longitudinal axis is offset from the second central longitudinal axis. One or more sensors are coupled to the sanding head. The one or more sensors are configured to detect presence of a metal within the predefined range.
