This paper describes a four-axis flexible force sensor using conductive material. The contact part of this sensor is composed of silicon rubber. The measurement part of this sensor is composed of three layers including the conductive material which is made of mixture of polycarbonate and vapor grown carbon fiber (PC/VGCF). The PC/VGCF is used as a pressure-sensitive material. In addition, neural network is used to estimate four-axis contact forces in consideration of a complex deformation of the flexible contact part.In this paper, the structure and fundamental characteristics of each part of the sensor is described. The experiment of estimation of four-axis contact forces by using neural network is carried out. It is confirmed that this sensor and contact force estimation system using neural network has a possibility to identify four-axis contact force.

The present work investigated the variation of internal structure, molecular orientation, crystallinity and mechanical characteristics of polypropylene(PP) after rolling process. The materials plate became narrow when rolled from entrance to exit, and the internal crystalline gradually deformed and at last destroyed. Plastic deformation was discovered along the rolling direction. In this direction, the crystallinity and vickers hardness were decreased, and molecular orientation was increased. Moreover, molecular orientation had a sharp increase at the second half part of rolling sample. The tensile stress of rolled samples increased by 80% parallel to rolling direction and decreased by 22% perpendicular to rolling direction.
