A new patent filing reveals that Apple is researching carbon fiber-like enclosures for future product designs, according to an AppleInsider report.
According to the filing the composite laminate includes a plurality of sheets of preimpregnated material, or prepreg, stacked one over another and a scrim layer provided on an exterior surface of the sheets of prepreg.
The scrim layer and the sheets of prepreg form a composite laminate whereby the scrim layer constitutes an outer, exposed surface of the composite laminate. Each sheet of prepreg is made from fibers preimpregnated with resin, and the fibers of the prepreg may be substantially parallel or woven carbon fibers. The scrim layer may be a glass fiber or carbon fiber scrim, or veil, that has absorbed resin from the sheets of prepreg during a molding process.
In another embodiment, the composite laminate includes a plurality of sheets of prepreg stacked one over another and first and second scrim layers provided on opposing exterior surfaces of the sheets of prepreg, whereby the sheets of prepreg are sandwiched between the first and second scrim layers. The first and second scrim layers constitute exposed surfaces of the composite laminate.
This design could "produce molded articles that have the advantageous properties of carbon fiber composites, without being limited to its black color or its imperfections in appearance."
