PURPOSE: To obtain a high strength composite panel with lightweight and excellent in fire resistance by constituting the subject panel of a surface layer and a core layer wherein a thermosetting resin, etc., are main ingredients and constituting the thermosetting resin of a phenol resin incorporated with a foaming agent.
CONSTITUTION: A composite panel with a bi-layered structure is constituted of a surface layer 5 wherein a mixture 1 of an inorg. powder and a thermosetting resin and a reinforcing fiber 2 are main ingredients and a core layer wherein a mixture 4 of an inorg. lightweight aggregate 3, an inorg. powder and a thermosetting resin is a main ingredient. Here, the thermosetting resin is a phenol resin incorporated with a foaming agent. As the foaming agent is positively used, the resin is filled into details of the powder and a matrix adhered on the surface of the powder with a larger pressure is formed. A composite panel with a extremely high strength can be obtd. thereby.
