ABSTRACT:
In production of a composite material such as an elongated Ti-base composite material advantageously used for eyeglass frames, a crude composite material formed by application of at least one surface layer of a component material to a base block by means of spraying processing is subsequently subjected to pressure application preferably with heat. A multi-layer construction can be easily obtained even starting from a base block of an intricate surface configuration thanks to employment of the spraying process, and the final pressure application assures strong diffusion bonding between the core block and the surface layers. The base block may be given in the form of a mold to be ultimately removed from the product.
