摘要： PROBLEM TO BE SOLVED: To obtain a new electromagnetic wave absorber that has a light weight, durability, and a superior electromagnetic wave absorbing characteristics over a wide band. SOLUTION: Conductive fibers are scattered in a foamed glass material. Since the foamed glass material is excellent in strength and durability, the foaming ratio of the material can be increased. When the foaming ratio is increased, not only the weight of the material is reduced, but also the pore (foam) portion of the material increases. Consequently, the reflection of electromagnetic waves by the conductive fibers becomes smaller and the electromagnetic wave absorbing effect of the material is improved over a wide band.

摘要： PROBLEM TO BE SOLVED: To remarkably widen use as a building material by putting the advantage of a foamed ceramic board to practical use while conquering a defect, and manufacture a large-sized board while easily attaching the foamed ceramic board to other members. SOLUTION: The inside of a box body 3 is filled with a plurality of foamed- ceramic board bodies 2 and the foamed-ceramic board bodies 2 are unified in the composite board 1. Since a plurality of the foamed-ceramic board bodies 2 are unified and one board is prepared, the large-sized composite board 1 not produced in conventional devices can be manufactured. The box body 3, in which a top face is opened, or the closed box body may also be used. Tensile strength and bending strength are increased by the box body 3, and the brittleness of a surface is also protected and solved by the box body 3. The composite board can be installed simply to other members such as a column, a beam, a floor joist, a ceiling foundation, etc. by nails, bolts, adhesives, welding,etc. by forming outwards projected flange sections 4 to the upper ends of the side facesor intermediate sections in the vertical direction of the box body 3, and application as a building material is widened remarkably.

摘要： PROBLEM TO BE SOLVED: To put the advantage of a foamed ceramic board to practical use while conquering a defect, to install the foamed ceramic board easily to other members and to widen application as a building material remarkably. SOLUTION: A foamed ceramic board body 2 is mounted and unified into a box body 3 in the composite board 1. The box body 3, in which a top face is opened, or the box body 3, in which the whole surfaces are closed, may also be used. Tensile and bending strength are increased by the box body 3, and the brittleness of the surface is also protected and solved by the box body 3. The composite board can be installed simply to other members such as a column, a beam, a floor joist, a ceiling foundation, etc., by nails, bolts, adhesives, welding, etc., by mounting outwards projected flange sections 4 on the upper ends of the side faces or intermediate sections in the vertical direction of the box body 3, and application as a building material is widened remarkably.
