The reinforcing effects of shirasu balloons and glass microballoons in solid polymers are investigated with respect to volume fraction of filled particles on the Young's moduli and yield stress of the reinforced composites. The effect of polyester resin coated on the surface of the shirasu balloons is also discussed in order to find a method to produce composites with high toughness and low density. The specimens were made from low density polyethylene as the matrix, glass microballoons and shirasu balloons as hollow particle fillers and polyester as the coating material.
