Why? The composite is designed to exhibit the best properties or qualities of its constituents or some properties possessed by neither. How? The combining of the two or more existing materials is done by physical means, as opposed to the chemical bonding that takes place in the alloys of monolithic solid materials. A true composite might be considered to have a matrix material completely surrounding its reinforcing material in which t
