Abstract

The invention discloses a metal composite component based on fiber reinforcement and a manufacturing method thereof. The metal composite component comprises a metal matrix, the metal matrix is provided with a plurality of grooves forming a preset angle with the horizontal direction, and the plurality of grooves are filled with a fiber material. According to the invention, based on the characteristics that the deformation at the necking position of the metal material is increased but the tensile bearing capacity is reduced, and the bearing capacity of the fiber material is increased along with the increase of the tensile deformation, the fiber material in the plurality of grooves with the preset angle and the metal jointly bear the tensile force. At a necking generation part, the reduction of the bearing capacity of the metal material is made up by enhancing the bearing capacity of the fiber material, so that the necking is avoided or necking at multiple parts is avoided, the metal composite component is prevented from being fractured due to local necking at one position, and the deformability of the metal composite component is improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a metal composite component based on fiber reinforcement and a manufacturing method thereof. Background technique [0002] Metal materials refer to the general designation of materials with metal characteristics composed of metal elements or mainly composed of metal elements, including pure metals, alloys, intermetallic compounds and special metal materials, etc. Metal materials have high temperature resistance, corrosion resistance, High ductility and other characteristics have become indispensable basic materials and important strategic materials for the national economy, people's daily life, national defense work, and scientific and technological development. [0003] Necking refers to the phenomenon that the local section of the material is reduced under the action of tensile stress. Due to the small difference in the effective cross-sectional area of ​​the existi...
