Abstract
The mechanical properties of low density phenolic resin syntactic foams with different volume fractions of glass microballoons were investigated by tensile, flexural and compression testing, SEM examination of fracture surfaces, and DMA. The results are discussed in comparison with those for syntactic foams based on an addition cure phenolic resin, propargyl ether novolac resin, in terms of potential aerospace applications. 27 refs.

Abstract
The synthesis of rigid polyurethane foam by reaction of polymeric diphenylmethane diisocyanate and polyether polyol in the presence of various proportions of different fillers, including precipitated silica, precipitated calcium carbonate and glass powder, and distilled water as blowing agent is described. The effects of filler type and content on mechanical, morphological and thermal properties of the foam were investigated by density, compressive strength, hardness, SEM, FTIR, water absorption, thermal conductivity, DSC and TGA, and the results are discussed. 15 refs.
