    Composite Materials

    Combination of two or more materials

    Designed to display a combination of the best

    characteristics of each material

    • fiberglass (strength from glass and flexibility from

    the polymer)

    Bonded together (adhesive) or mechanically lockedtogether

    Composite Materials

    Composite = matrix + fiber 

    atrix- component that s!rro!nds the fiber 

    -hold the fiber in a favorable orientation

    "iber - reinforcing material or fillers

    Classification of Composite

    Materials by Matrix:

    etal atrix

    Ceramic atrix

    #olymer ($esin) atrix

    Particle Reinforced Composites

    #article- a min!te portion of matter - no long dimension-

    any shape or si'e

    #articles !sed are- small mineral particles (ceramics and glasses)-

    metal particles (al!min!m)- amorpho!s materials (polymers carbon black)

    Particle Reinforced Composites

    #articles are !sed to- increase the mod!l!s of the matrix* and to

    decrease the permeability and d!ctility of the

    matrix- s!pport higher tensile* compressive and shear

    stresses- extend the strength or other properties of

    inexpensive composites

    Fiber Reinforced Composites

    "ibers- have very high mod!l!s of the matrix- have strong covalent bonds along fiber,s length-

    are diffic!lt to process-

     relatively expensive

    echanical properties depend on- properties of fiber -

    degree of load application- length of fiber* their orientation and vol!me fraction

    Fiber Alignment

    Contin!o!s "ibers- -ighest strength and stiffness

    Discontin!o!s "ibers

    - .sed only for man!fact!ring economics

    reinforcement pre%impregnated with a polymerresin that is only partially c!red

    - delivered in tape form to the man!fact!rer who

    then molds and f!lly c!res the prod!ct witho!thaving to add any resin
