The present invention discloses a film structure for a keycap, including a molding film presenting a shape conforming with the outline of the upper surface outline of the keycap; and a polyurethane (PU) layer disposing on the molding film and engraved a symbol thereon, wherein the symbol indicates a specific keycap. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

The present invention discloses a keycap for keys of a keyboard device, wherein the keys are configured on the keyboard, and the keycap is configured on a key body. The keycap includes: a top fabric layer, a keycap body including an upper surface outline, and a molding film. The top fabric layer is used for engraving to have a symbol thereon to transmit light therethrough, wherein each symbol indicates a specific keycap. The molding film is disposed between the top fabric layer and the keycap body to render the top fabric layer in a specific shape matching with the upper surface outline. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

The invention relates to a process for the production of finished parts made of at least one multilayer, fiber-reinforced, flat semifinished-product structure, comprising the following steps: a) heating of the at least one multilayer, fiber-reinforced, flat semifinished-product structure at ambient pressure to a first temperature T.sub.a, where the at least one multilayer, fiber-reinforced, flat semifinished-product structure comprises at least two mutually superposed polymer layers and the individual polymer layers respectively have fiber-reinforcement and do not have coherent bonding to one another or have only partial coherent bonding to one another, and in the event that at least one of the polymer layers comprises a semicrystalline polymer the first temperature T.sub.a is higher than a melting point T.sub.m of the crystalline polymer in accordance with DIN EN ISO 11357-3:2013-04, and in the event that the at least two polymer layers comprise no semicrystalline polymer the first temperature T.sub.a is higher than a glass transition temperature T.sub.g in accordance with DIN EN ISO 11357-2:2013-09 of a polymer comprised in at least one of the at least two polymer layers, b) pressing of the heated at least one multilayer, fiber-reinforced, flat semifinished-product structure to give a finished part at a second temperature T.sub.b and at a pressure p.sub.b of at least 3 bar.
