Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] see figure 1 , the present invention includes a reinforcement phase and a substrate 3, the reinforcement phase is two kinds of corrugated structures, respectively the first metallic glass corrugated structure 1 and the second metallic glass corrugated structure 2, and the substrate 3 is filled in the first metallic glass corrugated structure 1 and between and around the second metallic glass wave structure 2 . The first metallic glass corrugated structure 1 and the second metallic glass corrugated structure 2 are metallic glass, and the substrate 3 is made of high molecular polymer, porous material or common metal. Both the first metallic glass wave structure 1 and the second metallic glass wave structure 2 are composed of a number of units of the same size and shape that are periodically arranged. The first metallic glass wave structure 1 and the second metall...

Abstract

The invention discloses a metal glass composite material with a wave structure, which comprises a first metal glass wave structure, a second metal glass wave structure and a substrate. The first metal glass wave structure and the second metal glass wave structure are both composed of a plurality of units which are the same in size and shape and are periodically arranged. The substrate fills the space between and around the first metal glass wave structure and the second metal glass wave structure. The advantages of the composite material, the metal glass and the wave structure are combined, so that the composite material can be suitable for any metal glass system. The high strength of the metal glass is reserved, the shear band is controlled by using the wave structure, and plasticizing and toughening are conducted. Finally, a large-size, high-strength and high-toughness metal glass composite material is prepared. The material has the excellent characteristics of high strength, high toughness, energy absorption and storage, shock absorption, fatigue resistance, controllable performance and the like, and can be applied to many key fields.

Description

technical field [0001] The invention belongs to the field of composite material and structural optimization design, in particular to a metallic glass composite material with a wave structure. Background technique [0002] Composite materials are materials with new properties composed of two or more materials with different properties through physical and chemical methods on a macro or micro level. Generally, composites consist of a stronger, brittle, high-modulus reinforcement and a weaker, ductile, low-modulus matrix. Composite materials have the advantages of light weight, high specific strength, high specific stiffness, and good designability, which can meet the performance requirements of different fields. In recent years, composite materials have been widely used in many fields such as aerospace, automobile and ship, bridge construction, chemical industry and medical treatment. But at present, composite materials also face many bottlenecks, and the low overall strengt...
