FLAME-RETARDANT SHAPED OBJECT COMPRISING THREE-DIMENSIONAL WOVEN MATERIAL, AND PRODUCTION PROCESS

摘要

A flame-retardant shaped object which has flame retardancy and heat-insulating properties and which is lightweight and tough and can be used as a building material, an interior vehicular trim, etc.; and a production process therefor.The flame-retardant shaped object 101 comprises a three-dimensional woven material and is obtained by: infiltrating a mixture of a flame retardant and a polymer precursor into a three-dimensional woven object 100 having a structure configured of two woven materials for forming flat or curved surfaces, the woven materials each being composed of warps 11 and wefts 10 and having been disposed so that the woven materials face each other, and a third yarn 12, by which the two woven materials have been connected to each other at a large number of points so that a space is maintained between the two woven materials; and thereafter solidifying the polymer precursor mixture. According to the present invention, it is possible to obtain a flame-retardant shaped object that is effectively usable as, for example, building materials, interior vehicular trims, and the like which have flame retardancy and excellent heat-insulating properties and which are lightweight and have high strength. Hence, production of these is rendered possible. By designing the shape of the two woven materials at will, the flame-retardant shaped object is obtained not only in a flat shape but also in a curved shape.
