Abstract：
 The sewing method for composite fibrous material and sandwiched structure features wavy stitch with stitch of 0.2-10 cm, line space of 0.2-10 cm, wave length of 0.2-10 cm and wave height of 0.2-10 cm. The sewing method raises the shock resistance, the fatigue tolerance and the damage limit of the composite fibrous material, lowers the production cost and reduces dead weight, and the advanced composite material may be used in airplane, space flyer, transportation facility, weapon and other fields.
