Molding method for fiber-reinforced plastic structure and vehicle wheel

The present invention applies to a molding method for a fiber-reinforced plastic structure having an internal cavity. Firstly, grain groups, which mainly consist of a plurality of high-rigidity grains, are accommodated in bags, and a plurality of cores are formed. A reinforcing fiber substrate, is placed between the plurality of adjacent cores so as to be interposed therebetween. For example, a plurality of molding base materials are prepared by surrounding each core with a prepreg, and the plurality of molding base materials are combined and placed inside a molding die, and the molding base materials are compression molded. When compression molding, a part of the outer surface of the cores is locally pressurized, and the internal pressure of the cores is increased, changing the shape thereof, thus eliminating voids that are present between the cores and the prepreg and/or the prepreg and the molding surface of the die.

METHOD OF PRODUCING A COATED VEHICLE WINDSHIELD FOR A HEAD-UP DISPLAY (HUD)
20210107256 · 2021-04-15 ·

A method for determining pane thicknesses and a wedge angle of a coated windshield for a projection arrangement of a head-up display. A wedge angle and a combination of glass thicknesses are determined by means of which the glass ghost image and the layer ghost image are optimally reduced. The method proceeds from a starting thickness of the two glass panes of the windshield for which that wedge angle is determined, in an iterative process, that represents an optimal compromise between the minimization of the glass ghost image and the minimization of the layer ghost image. Then, the glass thicknesses are determined varied within a specified range for each combination of the optimal wedge angles. Thus, it is possible, iteratively, to identify that combination of glass thicknesses that results in the least occurrence of ghost images, in addition to the associated optimal wedge angle.
