Title:
COMPOSITE CONTAINER
Document Type and Number:
WIPO Patent Application WO/2017/073108
Kind Code:
A1
Abstract:
Provided is a composite container having an FRP layer formed so as to reinforce a dome part while suppressing weight addition as much as possible when FRP is wound on a metal liner for reinforcement. The present invention includes: a hoop layer (2) obtained by winding FRP on an entire body part (4) by hoop winding; and dome part reinforcing layers (9a) and (9b) obtained by winding FRP on dome parts (5) and (6) and the body part (4) at least near the dome parts (5) and (6). In the dome part reinforcing layers (9a) and (9b), the FRP is wound helically at the dome parts (5) and (6), and is wound so that the orientation angle of the FRP with respect to the axis direction of the liner (1) changes continuously on the body part (4) as the winding approaches the body part center (C) in order to reduce the weight of the FRP around the body part center (C).
