A fiber-reinforced resin composite material has a longitudinal direction, and includes a first stack, a second stack, a ridge, a flat surface, and a connection. The ridge extends in the longitudinal direction. The flat surface is continuous to the ridge. The connection is where the first and second stacks are coupled. The first and second stacks are joined to each other in a direction intersecting the longitudinal direction. Fibers of at least one of first fiber-reinforced resin sheets included in the first stack, fibers of at least one of second fiber-reinforced resin sheets included in the second stack, or both intersect the ridge. The connection includes the first and second fiber-reinforced resin sheets that are overlapped alternately, and includes ends of the first fiber-reinforced resin sheets, ends of the second fiber-reinforced resin sheets, or both that are shifted from each other to allow the connection to have a gradually-varied thickness.

A molding process for the production of a cover wall section for a cover in which the cover wall section has at least one multi-layer fabric that has a reinforcement and, at least on one side, preferably on both sides, a polymer coating, has the following process steps: Provision of at least one multi-layer fabric; draping of the at least one fabric over a molding surface of a mold and stretching of the at least one fabric across the molding surface by at least one tension element; and curing of the at least one fabric and/or the at least one tension element in such a way that the cover wall section is fixed in its shape.

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (ii) at least one consolidated fibrous insert (14) having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier may be a mass of activatable material.
