Abstract
The present invention relates to a structure for fastening composite structures, and more particularly, to a sewing machine for stitching composite materials which is capable of automatically and continuously stitching the composite structures by using a high-rigidity fiber in order to laminate and join the composite materials. The sewing machine for stitching composite materials according to the present invention automatically and continuously performs a stitching operation for joining composite materials by using a high-rigidity composite fiber for joining the composite materials, and as a result, it is possible to reduce process time for joining the composite materials and improve productivity.
Claims8
A sewing machine for stitching composite materials, the sewing machine comprising:
- a stitching needle having a hollow interior which is connected to a fiber storage reel to be supplied with the fiber and extend the fiber to the other end by pneumatic pressure;
- a stitching head unit which allows a vertical conveying head unit including the stitching needle to reciprocate upwards and downwards to stitch a joint portion of a stitching object;
- and
- a fiber cutting unit which cuts an upper end of a stitched fiber adjacent to the joint portion of the stitching object after each stitching is performed.
