MECHANICAL BEHAVIOR OF SANDWICH-TYPE COMPOSITES WITH WASTE OF FIBROUS MATERIAL AS CORE LAYER

摘要

The sandwich-type composites with fiber assemblage as a core layer was molded by applying a compression molding method to the waste cord assemblage and the mechanical behavior of molded composites was measured by the three points loading test. The waste cord of synthetic fabrics, cut waste of non-woven fabrics and pellet-type resin with/without glass fiber reinforcements were used as a surface layer respectively. A fairly poor adhesion at the interface between resin/reinforcements can be seen in the case of pellet-type resin with reinforcements used as a surface layer. Apart from some problem, the compression molding method described in this paper must contribute to material recycle of various wastes of fibrous materials as a sandwich-type composite with good insulating property.
