Measurement of the Young's modulus in particulate epoxy composites using the impulse excitation technique
A study of the Young's modulus as a function of the volumetric filler content in an epoxy matrix was carried out. To this aim, composites were prepared adding to the resin matrix particles of aluminum, copper and quartz with typical sizes of about 100μm. To measure values of the Young's mo...
