Abstract
A syntactic foam in the form of a thin uniform sheet that possesses enhanced moisture resistance, which comprises a composite filled with hollow microspheres such as glass in a polymer matrix resin such as an epoxy resin where the resin encapsulates the microspheres and the filled composite at weight equilibrium has less than 15% of the available internal volume of the microspheres occupied by liquid water as determined by the LMA test. The process of making the sheet and composites incorporating the sheet is described.
