Composite materials are the result of the union of two or more independent materials, with the purpose of obtaining a fusion that offers mechanical properties superior to those of each element separately. In nature we have three main types of materials: metals, ceramics and plastics or polymers. In general, each of these materials has a group of properties and at the same time disadvantages compared to the others. To counteract these weaknesses, the idea of composites arose.
With this combination of materials, it was possible to take advantage of the properties of metals, together with those of ceramics and polymers, and thus generate superior materials that are not easily found in nature. It is important to clarify that metal alloys or polyphase materials do not enter as composite materials since the characteristic of the latter is that they allow each material used in the fusion or assembly to be mechanically separated and distinguished.
A fairly popular composite material is aluminum composite, which we are going to talk about in more detail below:
