Water Absorption and Diffusion in Hollow Glass Microsphere Filled Epoxy Syntactic Foams

Abstract

The durability is very important in the research and application of polymers and their composites under different environmental conditions. The study of durability of patical filled epoxy resins had absorpted more attension in recently years, and the study of moisture absorption or water diffusion was almost along with the material manufacture. In the present work, the water sorption behavior in a series of different content hollow particle filled syntactic foams was studied by gravimetric measurements. The fashion factors on water sorption were discussed, and the change of density of syntactic foams on the subject was put forward.
