METHOD FOR CALCULATING FIBER ACCUMULATION CONTENT IN HIGH PRESSURE TANK

摘要

PROBLEM TO BE SOLVED: To provide a calculation method capable of improving calculation accuracy of a fiber accumulation content of a fiber-reinforced resin layer formed on the outer periphery of a liner.;SOLUTION: A method for calculating a fiber accumulation content includes: a step of multiplying a theoretical cross section area of a fiber-reinforced resin layer 50 in a dome portion 30 from a first point to a second point which are separated with a predetermined length in a radial direction from a central axis of a high pressure tank 10 in the fiber-reinforced resin layer 50 by a design value V_f(for design₎ of the previously set fiber accumulation content to calculate a used fiber amount; a step of measuring the cross section area of the fiber-reinforced resin layer 50 from the first point to the second point; and a step of dividing the used fiber amount by the measured cross section area to calculate a fiber accumulate content V_f(for design₎.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
