Fracture Behavior of Sandwich-Structured Fe-Based Amorphous Alloy Strip and ABS Polymer Composite Laminates

Sandwich-structured acrylonitrile butadiene styrene (ABS)/Fe-based amorphous alloy strip/ABS composite laminates were prepared for better mechanical behavior as structural material. Fe-based amorphous alloy, ABS sheet, and composite plates were studied by tensile testing with a high-speed camera. Tensile strength and elongation at break were compared. By combining the advantages of the good toughness of the ABS sheet and the high strength of the amorphous alloy, the strength and toughness of the sandwich-structured composite laminates are greatly improved. The Fe-based amorphous alloy and ABS have different macroscopic and fracture surface morphologies with the Fe-based amorphous alloy being brittle fracture while ABS is ductile fracture. The mechanical properties and fracture characteristics of sandwich ABS/Fe/ABS laminates are the result of the coupling effect of the amorphous alloy and ABS.
