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.
