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

Classification of Composite

Materials by Filler Type:

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)


7/29


#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

Composite Production Methods

"ilament 1inding

- Contin!o!s filaments wo!nd onto mandrel


24/29


#repreg #rod!ction

- composite ind!stry,s term for contin!o!s fiber

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
