Abstract

Phenolic resin has originally advantages of heat proof, fire retardant and less smoke during burning and these advantages are suitable properties in the construction field. In this paper, we present a development of pultrusion technique of phenolic foam composite materials composed of phenolic resin foam as matrix and roving glass fibers as a reinforcement in order to apply this composite to materials in the field of construction. A pultrusion technique can produce composites having the same cross section and optional length, and it is very useful because the volume and arrangement of fibers in the cross section of composite can be almost kept constant. In the case of molding phenolic foam composites, it is important to control the foaming time, and the foaming time can be controlled by a certain environmental temperature under cooling and heating. Furthermore it is also important to feed constant resin, and we develop the original feeder machine.
Next, this paper also shows mechanical strengths of the phenolic foam composite comparing with those of the candidate materials in the construction. As a result, the phenolic foam composite shows a possibility of application in the field of construction like natural woods. Additionally, measurement results of the thermal conductivity and flammability of phenolic foam composite are also shown.
