Effect of Short Fibers Reinforcement in Syntactic Foam: A Review

Abstract

Abstract Syntactic foam is a low density but high compressive strength material. Insertion of fiber reinforcements had increases density of the syntactic foam. However, it has widened its application by the ability of properties tailoring with natural fibers. Influences of fiber length, fiber contents, types of fiber and slab orientation on properties have been reviewed in this paper. On the other hand, to reduce the dependence of high-cost microsphere, fiber reinforced macrosphere has introduced recently. “Rolling ball” and “electrostatic fiber flocking” methods found effectively to lower density and the latter method has better performance reserved. Yet no further information can be revealed currently. On the other hand, uneven properties of natural fibers were unflavored from the material selection. Nonetheless, it will be a “requirement” in future of composite materials innovation. This review paper served as a bird’s eye view for researchers to review the effect of fiber reinforcements in syntactic foams.
