In September Apple was granted a mysterious patent concerning an Improved Laminate Composite material. Today we see that this new laminate composite could be playing a part in a new lighter and more flexible material that could end up in future generations of Apple's iPad in addition to new accessories like headphones and folio-styled cases. Apple's patent intrigues us with rich details about their new 3D knitting process that will produce these next generation materials. It's unknown at this time if Apple will use the lower cost material for entry units alone while retaining aluminum for their higher end units. However, considering that Apple likes to provide consumers with free engraving on such portables during the holiday season, I can't see this being extended to fiber based materials. Then again, time will tell. Update: Another patent has been added to this report that may point to an interesting twist to a future iPad.
