Functional compounds are materials with mechanical integrity, whose functional properties can be achieved, enhanced or enhanced by a combination of two or more components. ... Non-functional carbon material and two-and three-dimensional materials. Energy conversion and storage materials and structures. Compounds are generally characterized compounds (CAMCs). Polymer Matrix -Polymer matrix compounds (PMC) can be divided into three subtypes: thermoses, thermoplastic and rubber. A polymer is a large molecule formed by repeating structural units bonded by covalent chemical bonds. Structural compounds are engraved products made of plastic, wood, glass or carbon fiber materials. Developed or extruded products have applications such as exterior floors, rails, fences, natural wood, cladding, sidewall, molding, trim and window or door frames.

A particle is not a long dimension. Particle compounds the particles of one substance are scattered in the the second object team. Particles can have any shape and size, but generally spherical, a particle composite is classified as a group of suspended particles. Particles can have any shape, size or structure. Examples of well-known particle composites are concrete and particle board.
