A composite or composite material (also composition material) is a material which is produced from two or more constituent materials. [1] These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements.
In materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material. [1] [2] [3] It provides a theoretical upper- and lower-bound on properties such as the elastic modulus, ultimate tensile strength, thermal conductivity, and electrical conductivity. [3]
A small sample of aerospace grade carbon-fibre/epoxy laminate. In materials science, a composite laminate is an assembly of layers of fibrous composite materials which can be joined to provide required engineering properties, including in-plane stiffness, bending stiffness, strength, and coefficient of thermal expansion.
Knowing these parameters, the mechanical properties can be modeled based on effects from grain boundary strengthening, dislocation strengthening, and Orowan strengthening. [6] The most common particle reinforced composite is concrete, which is a mixture of gravel and sand usually strengthened by addition of small rocks or sand.
G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. [1] It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures. [2] [3] It is manufactured in flat sheets, most often a few millimeters thick.

In materials science, a metal matrix composite (MMC) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. The secondary phase is typically a ceramic (such as alumina or silicon carbide ) or another metal (such as steel [ 1 ] ).
This is a type of advanced composite group, which makes use of rice husk, rice hull, rice shell, and plastic as ingredients. This technology involves a method of refining, blending, and compounding natural fibers from cellulosic waste streams to form a high-strength fiber composite material in a polymer matrix.
