The new foamed aluminum material is a new type of lightweight functional-structure integrated material composed of aluminum or aluminum alloy matrix and pores. The special structure of the new foamed aluminum material determines its light weight, high porosity, High specific surface area and other characteristics, thus obtaining excellent properties that many dense metals do not have, such as strong energy absorption, impact resistance, high specific strength, electromagnetic shielding, sound absorption performance, high damping, low thermal conductivity, Low conductivity, etc. The performance of the new foamed aluminum material mainly depends on the pore structure parameters such as porosity, pore size, through porosity, pore structure type, specific surface area and the metal matrix.
Compared with dense metal materials, new foamed aluminum materials can be used as functional materials and structural materials. Generally, new foamed aluminum materials have both function and structure. They are durable and easy to recycle. It has huge application prospects in the fields of industry, military, aerospace and construction.
The application of new foam aluminum material as a structural material, due to the large number of pores inside the foam aluminum, which has the characteristics of light weight and high specific strength, it becomes an ideal filling material for lightweight composite sandwich panels or sandwich tubes. The new foamed aluminum material is used as the filler of the sandwich composite board, which is not only light in weight, but also high in strength and rigidity. The foamed aluminum filler can effectively improve the deformation mode of the composite board under static and dynamic loads, so that its bending strength and resistance Performances such as compressive strength, rigidity and energy absorption have been greatly improved. Compared with traditional honeycomb sandwich materials, the new foamed aluminum material has higher performance and better formability, and overcomes the shortcomings of anisotropy of honeycomb sandwich materials. The use of new foamed aluminum materials to replace expensive honeycomb sandwich materials can greatly reduce costs while achieving higher performance. In the construction industry, new foamed aluminum materials or other foamed metals can be made into light, hard, fire-resistant components, railings or supports, such as the high-frequency and high-speed acceleration and deceleration of modern elevators. It is particularly necessary to have both energy absorption and load-bearing characteristics. High-quality foam metal materials to reduce energy consumption.
