Syntactic foam
Videos
Syntactic foams are composite materials synthesized by filling a metal, polymer, cementitious or ceramic matrix with spheres as aggregates. The spheres may be hollow, called microballoons or cenospher

…composite materials synthesized by filling a metal, polymer, cementitious or ceramic matrix with spheres as aggregates. The spheres may be hollow, called microballoons or cenospheres, or non-hollow, for example perlite. In this context, "syntactic" means "put together." The presence of hollow particles results in lower…
