Apple is exploring the use of carbon fiber to create reinforced housing for its mobile devices, with the iPad a potential candidate to utilize the strong-but-light material.
The U.S. Patent and Trademark Office published a new patent application from Apple this week entitled "Reinforced Device Housing." It describes an outer shell for electronic devices composed of a "layered fiber-in-matrix type material, such as CFRP," otherwise known as carbon fiber-reinforced polymer.
… a hybrid material with the strength and anti-corrosive nature of metals like titanium and stainless steel, with the benefits of plastics and composites, such as extreme flexibility and easy casting.
I’m not fussed which cool new material they use – if it leads to a slightly lighter next iPad, I’m good with that.
