The specific embodiment

The shoe sole shell of relevant stereo modelling of the present invention is mainly implemented aspect as shown in Figure 1, 2, 3, at first please refer to shown in Figure 1ly, and shoe sole shell that should be made by fibrous composite comprises:

One base cloth layer 11, this base cloth layer 11 are that its stacked number of plies can increase voluntarily according to actual needs, subtract by braiding of fiber material or stacked forming;

One resin portion 12 is glued in the fibre gap of this base cloth layer 11 and coheres fiber, and the fiber of using with base cloth layer 11 forms composite wood structure 10 jointly, is to be the structure narration with epoxy resin as for resin portion present embodiment;

The thin layer 20 of one thermoplastic polyurethanes (TPU), hot pressing fits in this composite wood structure 10 surfaces, thin layer 20 is in conjunction with implementing aspect as shown in Figure 1, only hot pressing fits in composite wood structure 10 upper surfaces, or fit in as shown in Figure 2 on the composite wood structure 10, lower surface, also can be as shown in Figure 3, by last, thin layer 20 grades of two composite wood structures, 10 clampings, one TPU are implemented aspect for three kinds down, no matter and thin layer 20 adopts which kind of mode and 10 hot pressing of composite wood structure to fit, TPU thin layer 20 of the present invention is that to select polyethers TPU for use be main, this polyethers TPU does not then have the grease attribute of polyesters, so can with the easier bond of the epoxy resin of composite wood structure 10, marriage relation is also tightr, uses prolongation composite wood structure 10 and is used in combination the life-span advantage with the thin layer 20 of polyethers TPU;
