Abstract:
A protective case for a mobile device having a co-molded multi-layered construction having a first layer that generally forms the external back face surface of the case. A second layer generally forms the perimeter bumper of the case. The first layer is comprised of material that has a hardness and/or rigidity that is greater than the second layer. The layers are configured to interact with one another so that they are capable of distributing impact forces to mitigate damage to the mobile device. One or more reinforcing support members in the form of a beam or rod are provided and extend internally and longitudinally near the sides of the case and preferably near the long sides of a rectangular shaped case. The reinforcing support members are formed of even harder or more rigid materials, such as metal alloy or cured fiber reinforced composite rods or beams, relative to the first and second layer and are capable of providing additional support and rigidity to the mobile device to stop or mitigate unintentional or undesired bending of the mobile device.
Abstract:
A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.
Abstract:
A system for liquid composite molding includes a first rigid tool part onto which a semi-finished fiber material is positioned, a first vacuum foil arrangeable on the first rigid tool part to provide a first gastight chamber therebetween having a first port, a second vacuum foil and the first vacuum foil providing a second gastight chamber, and granulated material arranged in the second gastight chamber. The semi-finished fiber material is infusible with a matrix material via the first port. A second port is provided at the second gastight chamber for applying a negative pressure thereto. Therein, the granulated material is adapted for forming a second rigid tool part when negative pressure is applied to the second port. I.e. the first vacuum foil, the second vacuum foil and the granulated material function similarly to a vacuum mattress and may be stiffened and collapsed.
