摘要: Abstract The present work is aimed at characterizing syntactic foams for flatwise (specimen aspect ratio of 0.5) properties and investigating the effect change in internal radius cenospheres. density mechanical foam can be changed while keeping cenosphere volume fraction particle–matrix interfacial area same by using cenospheres outer but different inner radius. Five types cenospheres, with mean a radius, have been selected fabrication foams. ASTM C 365-94, standard compressive sandwich cores, followed work. results obtained study are compared edgewise 2) evaluated earlier Results show an increase strength modulus decrease peak were measured to higher specimens tested orientation that orientation. Varying only one parameter, helped understanding role matrix resin deformation fracture process
