- Transversal reinforcement of foam cores of aircraft sandwich-panels using tufting technology
Making a stitch using one thread and one needle without interweaving, and a base material penetrated by the needle during the process. When penetrating the material, a needle introduces a thread inside making a loop in the lower position of the needle. Loop formation is possible either inside or outside of the materials.
