PURPOSE:To obtain a composite body, in which an expandable phenol layer containing aggregate particles and a face material are unified, by covering the upper section of the face material with an expandable phenol resin composition and using the face material. CONSTITUTION:Two expandable resin-coated tabular bodies covered with expandable phenol resin compositions are manufactured, one tabular body is laid to a lower section, and a mold 4 is located on the tabular body while being conformed to the phen 1 expandable resin composition 1. The inside of a cavity 5 formed by a mold 4 is filled with perlite 6 in an approximately full manner, the other expandable resin-coated tabular body is positioned while downward directing a coated surface, the upper section of the tabular body is covered with a cover 8, and the mold 4 is located between press materials 7 and press- heated. Perlite particles 6 are dispersed uniformly to the whole phenol form in a phenol form composite body 9, and all of air gaps among particles are filled with the phenol form. |
