摘要： For reinforcing a wooden racket, uncured resin impregnated carbon fiber sheets with the fiber thereof being arranged in cross-ply pattern are tailored to adapt to the flat shape of respective portion of a wooden racket. Each fiber of the carbon fiber sheets 22 or 23 is oriented at an angle ranging from ± 25°c - ± 45° with respect to a longitudinal axis of a racket. A further thermoset resin impregnated carbon fiber sheet with the fiber thereof being arranged in cross-ply pattern are tailored to the desired length to supplement the weaker portion of the wooden racket. Each fiber of further carbon fiber sheet 25 is oriented at an angle ranging from 0° - ± 90° with respect to the longitudinal axis of the racket. By means of heat sealing, the above two sheets are bonded to form a fiber laminate for reinforcing the wood racket.
摘要翻译：为了加强木球拍，将未固化的树脂浸渍的碳纤维片材的纤维布置成交叉图案，以适应木制球拍的各个部分的平坦形状。碳纤维片22或23的每个纤维相对于球拍的纵轴以+/- 25℃+/- 45度的角度定向。另外的热固性树脂浸渍的碳纤维片材的纤维以交叉图案布置，被定制成所需的长度以补充木制球拍的较弱部分。另外的碳纤维片25的每个纤维相对于球拍的纵轴以0°+/- 90°的角度定向。通过热封，将上述两片粘合以形成用于加强木拍的纤维层压材料。
