Abstract
A method for manufacturing a composite material comprises the steps of furnishing a layer of a matrix material, forming a groove in the matrix-material layer using a laser to remove material from the layer of matrix material in the form of a groove, and placing a reinforcement into the groove. Preferably, the surface of the layer of matrix material is smoothed with a laser beam prior to formation of the groove. In most instances, more than one layer is desired, and the steps of furnishing, forming, and placing are repeated, using the same or different materials, to build up a multilayer composite material. Cylindrical, flat, or curved panel composite materials can be readily prepared, using metal, intermetallic, or ceramic materials for the matrix.
