Composite laminate and its use in sport articles such as shoes

Laminated composite material usable to make articles of manufacture, such as boots or other sports articles in particular. The laminate is a new basic material particularly directed to articles of manufacture having drastic mechanical requirements and which are very inexpensive and lightweight. The laminate has a sandwich structure having a core between two layers. More particularly, the core and the two layers are composites, and at least a portion of the fibers of the core have a mechanical strength significantly lower than that of at least a portion of the fibers of one and/or the, other layers. In a particular embodiment, the laminate has a thickness of 3 mm or less. The layers are sheets of carbon fabric embedded in an epoxy resin, and the core is made from non-woven polyamide micro-fibers having a thickness equal to 0.32 mm. The invention also relates to the manufacture of the laminate.
