Abstract: A vehicle wheel having a rim, or a rim of a vehicle wheel, is provided wherein the rim consists of a fiber-reinforced plastic material in the form of several layers of a fiber-reinforced semi-finished plastic product. The layers are shaped to form a finished component in a press while heat is supplied. The rim conventionally consists of a rim well, whose two sides are adjoined by a rim shoulder, which transitions into a rim flange. The rim well is formed by several layers of a base laminate, which extends to the rim flange, between which layers further layers are inserted in the area of the rim shoulder as well as of the rim flange. The further layers have an essentially tangential fiber alignment.

Abstract: In a method for producing fiber-reinforced preforms with a thermoplastic matrix, first individual precuts (11, 25) are generated from fiber-reinforced semi-finished products such as films, panels, webs or ribbons, said precuts are transferred by means of automated transport means (13, 27) onto a storage area and then joined by means of spot welding to form preforms.
