Title:
HYBRID ROUND BAR AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/017678
Kind Code:
A1
Abstract:
The present invention is to provide a method for manufacturing a hybrid round bar, in order to reduce the weight of an existing metal round-shaped bar such as a rod in a pneumatic cylinder, the method comprising a step of calculating the optimal ratio of a metal round bar and a composite material layer, when manufacturing a hybrid round bar in which the composite material layer is formed on the outer circumferential surface of the metal round bar. As such, the optimal ratio between heterogeneous materials can be derived, so that the weight can be reduced while satisfying a target buckling load when manufacturing the hybrid round bar. Thus, the present invention can contribute to reduction of the weight of round bars and tubes of metal materials and the weight of related apparatuses.
