A process is described for the production of holes, particularly of micro-perforations, in a composite material, constituted by fibers embedded in a resinous matrix, characterized in that it consists in a preliminary step of carrying out on a specimen of the composite material, with the help of a laser beam, tests consisting in adjusting the duration of illumination at a predetermined place on the specimen, as well as the focusing and power of said laser beam, so as to confine the temperature in the mass of the material to a range of temperatures both gr...
1. Process for producing holes (4 to 7), particularly micro-perforations, in a composite material, constituted by mineral or organic fibers (1, 2) embedded in a resinous matrix (3), characterized in that it consists:in a preliminary step, carrying out tests on a specimen of the composite material to be perforated, with a laser beam directed substantially perpendicularly to the surface of said specimen, said tests consisting in adjusting the duration of illumination at a predetermined position on the specimen, as well as the focusing and the power of said...
