Syntactic foam

英语百科

Syntactic foam

Syntactic foam, shown by scanning electron microscopy, consisting of glass microspheres within a matrix of epoxy resin.
Syntactic foam sphere used as a subsurface float in oceanographic mooring.

Syntactic foams are composite materials synthesized by filling a metal, polymer, or ceramic matrix with hollow particles called microballoons. In this context, "syntactic" means "put together". The presence of hollow particles results in lower density, higher specific strength (strength divided by density), lower coefficient of thermal expansion, and, in some cases, radar or sonar transparency.
