Molecular beam epitaxy, developed in the 1960's at the Bell laboratories, is a technique commonly used in semi-conductor research and industry to grow very high quality, single crystalline layers of semiconductors. However, MBE systems are dedicated to the growth of metal, either magnetic or non-magnetic, and various oxide (insulating) thin films.
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. Electronic semiconductor devices and optical coatings are the main applications benefiting from thin-film construction.
Fibre-reinforced plastic (FRP) (also fibre-reinforced polymer) is a composite material made of a polymer matrix reinforced with fibers. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper or wood or asbestos have been used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use.
FRP involves two distinct processes, the first is the process whereby the fibrous material is manufactured and formed, the second is the process whereby fibrous materials are bonded with the matrix during moulding. FRPs are commonly used in the aerospace, automotive, marine, construction industries and ballistic armor.

Carbon fiber–reinforced polymer, carbon fiber–reinforced plastic or carbon fiber–reinforced thermoplastic (CFRP, CRP, CFRTP or often simply carbon fiber, or even carbon), is an extremely strong and light fiber-reinforced polymer which contains carbon fibers.
The primary element of CFRP is a carbon filament; this is produced from a precursor polymer such as polyacrylonitrile (PAN), rayon, or petroleum pitch. For synthetic polymers such as PAN or rayon, the precursor is first spun into filament yarns, using chemical and mechanical processes to initially align the polymer atoms in a way to enhance the final physical properties of the completed carbon fiber.

Fiber reinforced plastic is a composite material that has its material properties enhanced by the tensile strength of various types and orientations of fibers within a polymer matrix. It is a commonly produced material and is less expensive than a Functionally Graded Material (FGM). FGM's are not readily produced, have limited practical application except in very specialized functions, and are not, to my knowledge, mass produced for general applications. They result from manipulating the microstructure of materials to change their material properties in response to the need at that particular location, usually in response to a gradient load of some type. A simple comparative example is that pavement sections would be an example of a macroscopic FGM whereas a true FGM is on a microscopic level but following a similar concept of gradient load attenuation and response. (Microscopic FGM would likely never be used as a pavement section because of cost!)

Composite materials are those containing more than one bonded material, each with different structural properties. The main advantage of composite materials is the potential for a high ratio of stiffness to weight. Composites used for typical engineering applications are advanced fiber or laminated composites, such as fiberglass, glass epoxy, graphite epoxy, and boron epoxy.
The most important characteristic of a composite material is its layered configuration. Each layer may be made of a different orthotropic material and may have its principal directions oriented differently. For laminated composites, the fiber directions determine layer orientation.
Sandwich structures have two thin faceplates and a thick, but relatively weak, core. The core is assumed to carry all of the transverse shear; the faceplates carry none. Conversely, the faceplates are assumed to carry all (or almost all) of the bending load.
