Abstract: A detachable vehicle roof is described herein. Various embodiments may include overhead covers, hinges, and a frame. The overhead covers may cover a vehicle passenger compartment. The hinges may connect the overhead covers to the frame. The frame may be detachable from a vehicle chassis. The frame may include a rear support bar, cross-bars, and a front support bar. The cross-bars may connect the front support bar to the rear support bar. The front support bar may form a contour of an edge of a vehicle windshield. The front support bar may form a contour of an edge of a vehicle chassis. The contour may have a bend corresponding to a position on the chassis where the windshield mounts to the chassis. A buffer zone may be provided between the front support bar and the windshield, and/or between the front support bar and the chassis.

Abstract: An out-of-autoclave compression molding system is disclosed herein. The system includes a mold, a vacuum bag, a vacuum valve, a pressure plate, and a pressure valve. The mold includes a concave feature and a flange. The vacuum bag covers at least the concave feature. The pressure plate is positioned outside the vacuum bag clamped to the flange and on the mold to form a pressure cavity between the vacuum bag and the plate. An out-of-autoclave compression molding process is also described. The process includes pressing a composite material and thermoset resin into a mold having a flange; surrounding the mold, composite material, and resin with a vacuum bag; sealing and evacuating the vacuum bag; clamping a pressure plate to the flange; and pressurizing the cavity.
