With the progress of science and technology, composite materials play an increasingly important role in the modern industry. Composite materials are formed by combining two or more different materials together to form new materials. The characteristics of these materials complement each other, resulting in better properties and performance than a single material.
High-purity aluminum oxide refers to aluminum with a purity of up to 99.99% or more. The filler used to make composite materials can be fine or nano-powdered aluminum oxide. The characteristics of aluminum oxide include high hardness, abrasion resistance, chemical stability and high temperature stability. These characteristics make it a very ideal filler. It is mainly used to enhance the rigidity and strength of the polymer base body and extend its service life. The following is the application of high-purity aluminum oxide in composite materials.
First of all, in composite materials, high-purity aluminum oxide fine powder is used to enhance the rigidity and strength of thermosetting resin. Because high-purity aluminum oxide fine powder is spherical particles, it increases the viscosity and fluidity of the composite material, and at the same time can effectively reduce shrinkage and thermal stress. When manufacturing composite materials, it is necessary to mix aluminum oxide fine powder into the resin to form a viscous mixture.
Secondly, high-purity aluminum oxide nanopowder body is used to make high-performance composite materials. Aluminum oxide nanopowder body can bridge the defects in the resin, reduce the looseness and internal fragmentation of the composite material, and improve the structural integrity of the composite material. At the same time, due to the small particle size of the nanopowder body, it can make it mix more evenly in the resin and produce a better composite effect. Such composite materials show good toughness and strength under load and temperature changes.
In short, the application of high-purity aluminum oxide in the manufacture of composite materials has a very wide application prospect. Although the cost of high-purity aluminum oxide materials is high, but its excellent characteristics enable it to play an important role in the manufacturing process of high-performance composite materials. With the continuous development of science and technology, people are paying more and more attention to the development and application of new materials, and the use of high-purity aluminum oxide fillers will gradually be widely popularized.
