A system and method is provided for manufacturing a composite structure. In an exemplary aspect, the system includes multiple flexible tooling plates that are interlocked to each other to form a tooling surface for forming a composite structure to be manufactured. Moreover, the system includes an actuator array connected to the flexible plates and that can move the flexible plates relative to each other to adjust a contour of the tooling surface to correspond to a design contour of the composite structure to be manufactured.

A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A method of manufacturing a glove assembly that includes obtaining an outer shell having an outer surface and an inner surface and turning the outer shell inside out, coating the inner surface of the outer shell with a waterproof coating, obtaining an inner liner, and securing the inner liner to the inner surface of the outer shell. The outer shell is made of a material that is waterproof and breathable.
