Abstract
The racquet frame (3) has a tubular, thin-walled, enclosed profile on the outside of which, facing the opening (4), is an inward-protruding, concave section (8) joined to the top and bottom cup parts (10, 11) by means of wall parts (9). The wall parts slope toward the plane of the strings at an angle of (alpha) of between 25 and 65 degrees. The profile is reinforced in the area of the outer, inward-protruding concave section. The frame's profile is made of composite material, and the reinforcement made of two overlapping layers of the composite material.
