The present invention relates to a composite with thermo-formability, a method for making the same and a method for making a casing with a texture on the surface thereof. The composite includes a polyurethane medium layer, a thermo-formable resin layer, a base layer and a surface layer. The thermo-formable resin layer is disposed on the polyurethane medium layer, and includes polyol. The base layer is disposed on the thermo-formable resin layer. The surface layer is disposed on the base layer. As a result, the composite has good stability after thermoforming, and plastic can be injected into the composite, so a PC film is unnecessary. Moreover, the composite may be adhered to a substrate directly or after thermoforming.
