    摘要： A games racket frame comprising a main frame (1) in the form of a hollow tubular structure made of a fibre reinforced composite including a thermosetting material, and at least one additional component (2, 3 or 4) including a thermoplastic material and integrated with the main frame (1) in order to improve the vibration damping characteristics of the main frame. The additional component (2, 3, or 4) is preferably made of a composite comprising the thermoplastic material and a discontinuous fibre reinforcement, and can form the bridge of the racket frame.

    摘要： The present invention provides a compound material frame body without the need of drilling holes. A plurality of symmetric embedded tubes are clamped between two compound material pipe bodies. An outmost compound material layer sheathes the compound material pipe bodies and the embedded tubes with two openings of each of the embedded tubes being exposed. An integrally formed compound material frame body having through holes can immediately be obtained by blowing and heating in a mold. Because there is no need of drilling holes, the structure of the frame body will not be damaged. Moreover, the present invention can achieve the effects of simple manufacturing process, short manufacturing time, and reduced cost.
