The paper is focused on composite materials with a polymer thermosetting matrix reinforced with long (continuous) fibers. These materials offer their specific properties that can be used in various areas of industry. From this point of view, polymer mat rix composites are, due to their mechanical properties and low weight, the most promising material for use in various application solutions. However, their disadvantage is the high price, which is higher than the price of conventionally used materials. The method of production of components from composite materials itself requires precisely specified technological procedures, which differs slightly from the traditionally used methods of component production, e.g. of metal materials.
