Title:
FIBER COMPOSITE HOSE
Document Type and Number:
WIPO Patent Application WO/2017/078124
Kind Code:
A1
Abstract:
[Problem] To decrease fluid pressure loss and decrease reduction of fluid flow by the hose inner surface having specific shapes of protrusions and recesses. Also, for weight reduction, to make the specific gravity of the thermoplastic resin configuring the hose to be 1.0 or less. To make the hose to have pressure resistance performance, abrasion resistance and durability. [Solution] A fiber composite hose that is obtained, in order from the hose inner circumferential surface, from a soft resin layer (A)/reinforcing fiber layer (B)/outer surface resin layer (C)/reinforcing hard core (D), and that satisfies all of conditions (1)-(3) below. (1) When expanded in the longitudinal direction of the hose, 5 mm ≤ X ≤ 25 mm when the repeating unit of the apices of the inner protrusions is X (mm). (2) When the depth of the depressions between the hose inner protrusions is Z (mm) and the hose internal diameter is ID (mm), 0.003 ≤ Z/ID ≤ 0.05. (3) The specific gravity of the thermoplastic resins forming the soft resin layer (A) and the outer surface resin layer (C) is 1.0 or less.
