Abstract: A method for providing motor vehicle wheels made of composite material based on carbon fiber includes the steps of dividing each wheel into a plurality of portions having small dimensions; providing a a first portion with the terminal edges designed to mate with corresponding edges of a respective second portion; mating the portions, arranging them subsequently within a respective mold whose shape and dimensions are conjugate with respect to those of the wheel to be manufactured; and bringing the mold and its contents to a predefined temperature. The method further includes injecting into the mold a resin in the liquid state, the resin being injected at high pressure and high temperature, forming the matrix of the composite that constitutes the wheel; maintaining the pressure and temperature of the mold within predefined ranges for a time interval that is required for the at least partial cross-linking of the resin; and extracting the wheel from the mold.

Abstract: A method for producing a fiber-reinforced plastic component including: cutting individual fiber mats to size; stacking multiple fiber mats to form a fiber semifinished product outside or inside a molding tool, which comprises at least two tool parts; performing a preform process to produce a fiber preform of the plastic component; and performing an RTM process to produce a main form of the plastic component. The method is distinguished by application and/or introduction, which is before, simultaneous, and/or after, of an at least partially circumferential sealant material, which is suitable for use as a sealant, to individual, multiple, and/or all fiber mats and/or the fiber semifinished product; wherein the application and/or the introduction of sealant material is performed such that at latest before the performance of the RTM process in a particularly completely circumferential edge region of the fiber preform, all fiber pores and intermediate spaces therein are closed by the sealant material.
