摘要： A vehicle sandwich structure composed of a foamed resin article in sheet form forming the core, a fiber-reinforced composite layer forming a surface material that is located on one or both sides of the foamed resin article in thickness direction; forming a binding layer of core and surface materials between the foamed resin article and the fiber-reinforced composite layer; a large number of glass fibers being inserted within said foamed resin article; more than 70% of total glass fibers being the glass fibers which form an angle between the longitudinal direction of each glass fiber and said foamed resin article, the angle of which satisfying a range from 45° to 90°.

摘要： A flexible second gas barrier for a liquefied gas storage tank which includes a stiffener fabric weaved with two or more kinds of fiber yarn selected from a group consisting of a glass fiber, a carbon fiber, an aramid fiber, and a synthetic fiber. The stiffener fabric is weaved so that a hybrid fiber yarn is made by 2-ply yarning two or more kinds of a single yarn or a twisted yarn of fiber yarn selected from a group consisting of a glass fiber, a carbon fiber, an aramid fiber, or a synthetic fiber, is included in the weft and/or warf so that repeated fatigue resistance, even under cryogenic conditions, is achieved, which ultimately has the effect of solving the problems associated with repeated load increase imposed on the second gas barrier as the thickness of LNGC Foam increases.
