Abstract

Abstract Micro-arc oxidation (MAO) is used for interface modification of biodegradable poly(lactic acid) (PLA) based composite reinforced with magnesium alloy sheets (MASs/PLA). The intermolecular force and strong mechanical interlocking between the MgO and PLA play a significant role in the interface strengthening. Tensile-shear tests reveal 3 times improvement of the interface tensile-shear strength after MAO treatment of MASs, thereby leading to the enhanced macroscopic properties of the composite plate. Investigations based on the lamination theory suggest the tensile stress of PLA on the bottom of composite plate can be improved from 38 MPa to 47 MPa by interfacial constraint strengthening derived from MAO. The experimental and theoretical analysis of mechanical properties of the Mg/PLA composites is useful for further optimizing their preparation technology.
