Apple may be mulling plans to use a Carbon Fiber chassis rather than an aluminium one for the iPad 2, a move that could make the device even lighter & sturdier than it is at the moment.
Jeremy Horwitz, editor-in-chief of iLounge, says that a source told him that the company has already produced shells for the iPad 2 which have been spotted in the wild.
Apple already applied last November for a patent labelled "reinforced device housing", one which it says would be a housing for an electronic device or other object formed from a fiber-in-matrix material. It also mentions that certain metals may be used, which would be essential in the case of the iPad's antenna.
The iPad tablet weighs 680g for the Wi-Fi only model and 730g for the 3G one; switching to a Carbon fiber-reinforced polymer - which is used in the fuselage of the Boeing 787 - means adopting a material which has 10 times the tensile strength of steel.
This could bring the weight of the iPad 2 down to around 500g; however CFRP in general is not environmentally friendly because it uses epoxy resin and fibres and cannot be recycled.
