The invention includes the use of a high-modulus fiber metal matrix composite material as a backing plate for physical vapor deposition targets, as a lid for microelectronics packages, as a heat spreader, and as a heat sink. The process includes guiding the fibrous web and the felt through the at least one press nip formed between the smooth roll and the at least one opposing element, and passing the fiber web, in an unsupported manner, over a free draw from the smooth roll onto an embossing belt. The directivity conversion pattern is configured by arranging V grooves in parallel to each other, each having a vertical angle of 120\xb0, and each extends in a direction approximately perpendicular to a light incidence end face of the light guide plate.
