▎ 摘　　要

NOVELTY - Syntactic foam comprises a matrix material and multiple microspheres embedded within the matrix material, where multiple microspheres comprises a metallic glass material. USE - Syntactic foam used as lightweight alternatives to metals, PVCs, and conventional composites in a variety of automotive, aviation, and energy industries. ADVANTAGE - The syntactic foam improves the tensile properties and high-temperature performance of the syntactic foam. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A method for lightweight, tough, resilient syntactic foams with enhanced strength and resistance, which involves: embedding multiple microspheres in a matrix material to produce a syntactic foam, where multiple microspheres comprises a metallic glass material. An apparatus, which comprises a tool for use within wellbore. The tool comprises a syntactic foam, which further comprises a matrix material, which comprises polymer material and multiple hollow microspheres embedded within the matrix material, where multiplehollow microspheres, comprises a metallic glass material. DESCRIPTION OF DRAWING(S) - The drawing shows cross-sectional diagram of a wellbore system. 100Wellbore system 110Rig floor 114Wellbore 149Plugging flowable component 150Syntactic foam
