A new fabrication method to improve metal matrix composite dispersibility

A new type of periodic cellular metal called wire-woven bulk Kagome (WBK) was used as a precursor for creating the composite materials with improved dispersibility. Preheated and non-preheated preforms were placed into molds, and then molten aluminum was poured into them to fabricate composites. The effects of preheating on the wettability and interfacial reaction between the aluminum matrix and the WBK preform were then investigated. The preheated preform composite had good wettability compared to the non-preheated preform composite. Interfacial phenomena between the aluminum matrix and the WBK preform were observed. Our research offers a new avenue for solving the problem of composite material dispersibility.
