Description

technical field

[0001] The invention relates to the field of preparation of aluminum alloy materials, in particular to an impact-resistant aluminum alloy composite plate and a preparation method thereof. Background technique

[0002] With the development of high-speed, low-cost, and lightweight industrial applications such as automobiles, rail transit, construction, aerospace, and military, traditional steel materials are gradually being replaced by aluminum alloys and aluminum alloy composite materials. The mechanical properties of aluminum alloy composites put forward higher requirements. For example, in extreme cases, such as high-speed impact, collision, explosion and other instantaneous impact dynamic loads, the material must have a comprehensive matching of high strength and good plasticity and toughness to ensure the material's resistance to high-speed impact damage, so that Ensure the safety of relevant personnel and the reliability of equipment.
