In addition to investing in the LiquidMetal process, Apple also is actively investigating the potential for carbon-fiber reinforced plastics (CFRP), the same material used in the Boeing Dreamliner 787. Apple received a U.S. patent yesterday for a fiber-reinforced housing, apparently intended to replace aluminum in the iPad in response to complaints about the device’s weight. The first version of the iPad weighs just 1.5 lb, but the next version may use new materials technologies like carbon fiber to reduce its weight and make e-reading more comfortable.
The patent also covers issues that might create challenges to the design team. These additional claims address issues pertaining to the molding process to create perfect parts suitable for Apple.
