description | The footwear insoles and heel counter stiffeners are made using fibrous structure materials. The spatial forming of these parts is made in moulds. After forming, the parts must have the same spatial dimensions with those of the shoe lasts used in the footwear manufacturing. During the forming process, the fibrous structure materials have an elastic-plastic behavior. So, for the moulds dimensioning, it is important to know the percentage of plastic deformation from the total deformation of the stressed material; this means to know the value of these materials forming subscript. The paper presents some theoretical and experimental contributions in finding of the forming subscript of the materials used in the footwear industry, for the footwear insoles and heel counter stiffeners manufacturing. Experiments were made on installations and experimental moulds sphere, cylinder and central angle. Experimental results shows that the forming subscript depends on the mould shape and the sample humidity when the stress is cancel. So, the deformations have a high rate, the sphere surfaces having the, highest forming subscript. In the case of sample forming which use cylinder moulds the value of the forming subscript on these surfaces is the lowest. In the case of the center angle occurs a a high level of plastic deformation. The results will be applied at the designing of the insoles and heel counter stiffeners moulds used for the pre-moulding. |
