Composite resin is one of the most important materials used in all industrial and medical fields nowadays, but it has many properties and advantages that distinguish it from metals. Many problems appeared previously due to the materials used and to overcome these problems, A composite resin with great physical and mechanical properties and compatibility has been developed. Composite resins are resin filled with high compressive strength, corrosion resistance, light weight, ease of application and high transparency. The objective of this review article is to review composite materials, including the most important conditions and the ratios affecting them. The literature on composite materials and the measurement of many physical properties, research methodologies, and contributing factors are selected and reviewed
