Processing of Hollow Glass Microspheres (HGM) filled Epoxy Syntactic Foam Composites with improved Structural Characteristics

Abstract: The objective of this work is to improve the structural characteristics of hollow glass microsphere (HGM) filled epoxy syntactic foam composites with little voids content and improved HGM dispersion in the composite. A modified degassing technique has been introduced during resin casting process of the HGM filled syntactic foam composites. The effect of HGM content volume fractions (5–25%) on the degassing techniques was examined. The syntactic foam composites were characterized by analysing str… Show more

“…As a result, all the composites revealed a decrease in density values as the HGM content increased. Similar trends can be observed in [14,[28][29][30]. Furthermore, HGM/E composites revealed lower density as compared with HGM/CNT/E and HGM/G/E.…”

“…He analyzed and studied foam composites by means of scanning electron microscope, transmission electron microscope, and density measurement. e analysis results show that the improved degassing technology can significantly reduce the porosity of composite foams [6]. Wu et al discussed the preparation and mechanical properties of carbon fiber reinforced polyphase epoxy composite foam.…”
