Hello. I am in need of composites kowhow to improve the upper limb prosthetic for congenital amputated girl (my daughter). Utter newbie, aware of the basics about composites but without any practical experience. Looking foward to get advise from experienced users and share my findings for disabled people to profit. The matter of issue is the sock that warps the forehad to hold a electrically driven mechanic hand on the edge. I'll try to start replicating this spiral with the idea of substituting the rigid sock decribed in the image. Any ideas, critics or thoughts are welcomed. Thanks.
