摘要: Syntactic foams based on a reactive polymer blend of Epoxy-Allyl Phenol-Bismaleimide were processed using hollow glass microballoons. The effect microballoon concentration the mechanical and thermophysical properties foam composites was investigated. properties, specific strength, coefficient linear expansion, density showed decreasing trend with increase in whereas heat marginal increase. temperature dependence revealed an more or less insensitive to test temperature. fixed filler loading (50% by weight) two types microballoons different shell thickness. increased proportional higher thickness microballoon. At moderate load breakage dominated failure mode. compositional dependency corroborated SEM analysis fracture surfaces. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci,
