    摘要: Provided is a manufacturing method for manufacturing a high-pressure tank by infiltrating resin into a fiber layer of a preform in which the fiber layer is formed on an outer surface a liner. The manufacturing method includes: a first supply step of supplying resin to the fiber layer of the preform; and a second supply step of, after the first supply step, supplying, to the fiber layer, resin to which spherical particles are added.

    摘要: A reduced vibration structure comprises honeycomb and a vibration damping coating on at least a portion of the internal surface of at least a portion of the cells of the honeycomb. The vibration damping coating is formed by curing a coating composition comprising acrylic polymer or copolymer emulsion and a vibration damping filler. The structure can include an adhesive coupled to both the upper surface and the lower surface of the honeycomb and two pieces of sheathing coupled to the adhesive, one on the upper surface and one on the lower surface of the honeycomb.
