Abstract

An improved racquet, such as a tennis racquet, which may be manufactured by way of an injection moulding method rather than by hollow resin casting, using a corrugated skeleton structure for its frame construction, which acts to reduce drag and to modulate racquet frame resonancy, increasing efficiency of such racquet at a more consistent quality level and reduced production cost.
