The In the 1960s, composite materials began to spread. These are materials that are made up of two different materials or more, and each material gives its best properties to obtain a compound with distinctive characteristics, the first of which is a reinforcing material that can be in the form of fibers made of high-resistance materials (such as carbon or glass fibers, for example), and the second material is one of plastics or colloidal polymers (Matrix), which give the final product its required form and it is called the incubator, and the mechanical properties of the final product are different from those of any of its composites. Composite materials have spread tremendously during the short period of their life due to their excellent mechanical properties compared to their low weight, they have entered all engineering fields, although they were originally born in the world of aircraft and spacecraft industry, where light weight plays a major role in the selection of materials. All objects designed from composite materials are assumed to have long life, so the materials involved are non-dissolved. However, this feature has recently become undesirable due to the difficulty in disposing of compounding materials after their useful life. For these reasons, research has recently tended to arrive at green composite materials that are organic biodegradable so that they degrade in the soil after being buried, i.e. as living organisms after their death, or they are reusable after the end of their life. The paper presents the latest developments in three important areas related to composite materials. The first is in the manufacture of fiber-reinforced bars, the second in technical requirements and the precautions to be known, and the third in use and its future in the construction industry in Sudan.
