1.2.3TypesofCompositeMaterials

ØTherearefivebasictypesofcompositematerials:

Fiber,particle,flake,laminarorlayeredandfilledcomposites.

A.FiberComposites

Ø1-Dgivesmaximumstrengthinonedirection.

Ø2-Dgivesstrengthintwodirections.

ØIsotropicgivesstrengthequallyinalldirections.

ØCompositestrengthdependsonfollowingfactors:

✧Inherentfiberstrength,Fiberlength,Numberofflaws

✧Fibershape

✧Thebondingofthefiber（equallystressdistribution）

✧Voids

✧Moisture（couplingagents）

B.ParticleComposites

ØParticlesusuallyreinforceacompositeequallyinalldirections（calledisotropic）.Plastics,cermetsandmetalsareexamplesofparticles.

ØParticlesusedtostrengthenamatrixdonotdosointhesamewayasfibers.Foronething,particlesarenotdirectionallikefibers.Spreadatrandomthroughoutamatrix,particlestendtoreinforceinalldirectionsequally.

ØCermets

✧Oxide–BasedCermets

✧Carbide–BasedCermets

ØMetal–plasticparticlecomposites

ØMetal–in–metalParticleCompositesandDispersionHardenedAlloys

C.FlakeComposites

ØFlakes,becauseoftheirshape,usuallyreinforcein2-D.Twocommonflakematerialsareglassandmica.（Alsoaluminumisusedasmetalflakes）

ØAflakecompositeconsistsofthin,flatflakesheldtogetherbyabinderorplacedinamatrix.Almostallflakecompositematrixesareplasticresins.Themostimportantflakematerialsare:

✧Aluminum

✧Mica

✧Glass

ØBasically,flakeswillprovide:

✧Uniformmechanicalpropertiesintheplaneoftheflakes

✧Higherstrength

✧Higherflexuralmodulus

✧Higherdielectricstrengthandheatresistance

✧Betterresistancetopenetrationbyliquidsandvapor

✧Lowercost
