According to Macotakara, a fairly reliable source for supply-chain news and rumors, Apple is looking in to incorporating carbon fiber in to an upcoming product.
According to my source, some engineer of Apple and Foxconn Technology came on Japanese company, which has carbon production in mid-March, and they requested to develop some sample.
I don’t have information which is ordered by Apple, source told the number of parts is too large to be called “sample”.
The above translation was done by Macrumors, who also points out that a fairly recent hire by Apple might add weight to this idea. Kevin Kenney was hired in April of last year, but before that Kenney worked as an engineer for one of the pioneers of carbon fiber.
It’s unclear what product Apple is looking to use this in: personally, I could see it being used on the larger devices, such as a new backing for the iPad, or even in a next-generation case for future MacBooks. Using it on the iPad would make sense, as it would help cut down on the weight without sacrificing structural integrity. Regardless, more and more signs are pointing to Apple being interested in expanding its materials beyond the staple of aluminum – and it appears that carbon fiber could be their choice.
