Teijin Limited has announced the incorporation of its materials, Tenax TPCL, a carbon fiber intermediate material, and Panlite Sheet, a polycarbonate (PC) product, into the housing of the world's lightest (for mobile displays with a screen size of 14.0 inches or larger) portable displays developed by VAIO Corporation.
The VAIO Vision+ 14 and the VAIO Vision+ 14P, subsequently referred to collectively as VAIO Vision+, were launched by VAIO in Japan in early July. The Teijin materials have made it possible to achieve the lightest weight portable display, weighing approximately 325g, with the thinnest point measuring approximately 3.9mm.
Tenax TPCL intermediate, used for the VAIO Vision+ housing's top and bottom layers of the sandwich construction, is a sheet-like material made of woven carbon fiber impregnated with thermoplastic resin. It is lightweight, resistant to heat and impact, strong and rigid, and also meets flame retardancy requirements for electrical products.
In addition, Panlite Sheet, made from PC resin and used for the middle layer, has excellent dimensional stability, light weight and impact resistance. VAIO Vision+ is a portable display that uses a carbon fiber reinforced thermoplastic resin housing.
Reduced CO2 and easier manufacturing: Conventional housings use metal parts for assembly, which need to be installed during the manufacturing process. However, the housing of the new displays, which has a structure that sandwiches Panlite Sheet between Tenax TPCL layers, achieves the shape and strength of the connections necessary for assembly without the need for metal parts.
This material solution makes it possible to manufacture complex, three dimensional shapes in a single molding step, which helps reduce the number of steps required to manufacture the housing, and cuts CO2 emissions. The Teijin Group aims to become a company that protects the global environment, embodying its long-term vision of becoming a company that supports the society of the future, and will continue to utilize a wide range of highly functional materials to provide solutions in a variety of fields.
