Pultrusion technique and evaluation of sandwich beam which used phenol foam composite as core

摘要

Phenolic resin has originally advantages of heat proof, flame proof and less smoke during burning and these advantages are suitable properties to structures in various fields. We have presented a development of pultrusion technique of the phenolic foam composite (PFC) using phenolic resin foam as the matrix and roving glass fibers as the reinforcement. In addition, this PFC can be used as the core in the sandwich beam having faces of phenolic GFRP or CFRP. In order to apply this sandwich beam (SWPFC) to structural members in the various fields, mechanical properties of this sandwich beam are evaluated.
