Title:
HOSE, METHOD FOR MANUFACTURING HOSE, AND HYDRAULIC PUMP
Document Type and Number:
WIPO Patent Application WO/2021/172489
Kind Code:
A1
Abstract:
Provided are a hose excelling in a lightweight property and in fatigue fracture resistance, a method for manufacturing the hose, and a hydraulic pump. The hose comprises a tube that is hollow on the inside, continuous carbon fibers and/or continuous glass fibers wound around an outer circumference of the tube, and a thermosetting resin present on the exterior of the tube. The thermosetting resin has an elastic modulus of 0.5-10 MPa, and at least some of the thermosetting resin is impregnated into the continuous carbon fibers and/or the continuous glass fibers. The elastic modulus of the thermosetting resin is a value obtained by heating the thermosetting resin for 2 hours at a curing temperature of the thermosetting resin, and then subjecting to temperature control for two weeks under conditions including a temperature of 23℃ and a relative humidity of 55%, and then measuring in accordance with JIS K7161:2019.
