Qhov sib txawv tseem ceeb ntawm matrix thiab dispersed theem nyob rau hauv composites yog hais tias lub matrix theem yog ib tug tas mus li theem, whereas lub dispersed theem yog ib tug discontinuous theem nyob rau hauv composites.
Ib qho khoom sib xyaw yog tsim los ntawm kev sib txuas ob lossis ntau cov ntaub ntawv, ua kom muaj kev sib xyaw ua ke ntawm cov khoom tsis muaj nyob hauv ib tus neeg. Feem ntau, cov khoom siv sib xyaw ua ke yog tsim nrog cov theem tsis tu ncua thiab tsis tu ncua. Cov theem txuas ntxiv yog qhov tseem ceeb ntawm cov khoom siv sib xyaw thiab sau qhov chaw hauv cov khoom sib xyaw. Nws muaj cov khoom uas ua rau lub matrix ntawm cov khoom, li no, lub npe matrix theem. Lub discontinuous theem, ntawm qhov tod tes, yog cov khoom uas muaj nyob rau hauv lub matrix ntawm cov khoom thiab muaj ob peb yam embedded nyob rau hauv lub nruam theem. Nws tsis tas mus li vim cov khoom sib txuas tsis txuas rau ib leeg ib yam li nyob rau theem tas mus li.
Feem ntau, cov theem matrix lossis theem txuas ntxiv yog nyob ib puag ncig los ntawm theem tawg lossis ntu ntu. Lub matrix theem nyob rau hauv composites yog lub nruam lub cev constituent uas nyhav rau enclose lub composite thiab muab bulk daim ntawv rau cov khoom sib xyaw. Theem dispersed nyob rau hauv composites yog lub discontinuous theem ntawm composite cov ntaub ntawv uas txiav txim lub internal qauv.
Matrix Phase hauv Composites yog dab tsi?
Theem matrix hauv cov khoom sib xyaw yog lub cev txuas ntxiv uas zoo li muab cov khoom sib xyaw thiab muab cov ntaub ntawv ntau rau cov khoom sib xyaw. Cov theem no tuaj yeem yog cov khoom siv polymer, hlau, lossis cov khoom siv ceramic. Yeej, cov matrix yog homogenous thiab monolithic cov ntaub ntawv uas peb tuaj yeem soj ntsuam cov kab ke fiber ntau ntawm cov khoom sib xyaw uas tau kos. Cov theem no tau ua tiav tas mus li, thiab nws muab qhov nruab nrab rau kev khi thiab tuav cov kev txhawb nqa ua ke los tsim cov khoom siv.
Daim duab 01: Kev faib tawm ntawm cov khoom sib xyaw
Daim duab saum toj no qhia txog kev faib tawm ntawm cov khoom sib xyaw. Cov khoom sib txawv no muaj cov khoom siv sib txawv uas tau tawg mus rau theem matrix.
Dab tsi yog qhov Dispersed Phase hauv Composites?
Theem dispersed nyob rau hauv composites yog lub discontinuous theem ntawm composite cov ntaub ntawv uas txiav txim lub sab hauv. Peb tuaj yeem hu rau theem no yog theem uas tau tawg nyob rau hauv colloidal particle zoo. Ntxiv mus, qhov nruab nrab nyob rau hauv uas cov colloidal hais raug faib yog hu ua nruab nrab ntawm dispersion.
Daim duab 02: Fiber-reinforced Composite Hom. (a) nruam fiber ntau-reinforced, (b) discontinuous aligned fiber-reinforced, thiab (c) discontinuous random-oriented fiber-reinforced composite cov ntaub ntawv
Feem ntau, cov theem dispersed tseem hu ua lub zog ntxiv, thiab nws tau tuav ua ke los ntawm matrix theem. Cov theem dispersed txhim kho tag nrho cov khoom ntawm matrix. Nws muaj zog yog qhov kev txhawb zog muab qhov ntom ntom.
Dab tsi yog qhov txawv ntawm Matrix thiab Dispersed Phase hauv Composites?
Cov khoom siv sib xyaw yog ua los ntawm ob theem: theem matrix thiab theem dispersed. Theem dispersed yog tuav ua ke los ntawm matrix theem. Cov theem dispersed zoo li txhim kho tag nrho cov khoom ntawm matrix. Qhov tseem ceeb sib txawv ntawm matrix thiab dispersed theem nyob rau hauv composites yog tias lub matrix theem yog ib tug tas mus li theem, whereas lub dispersed theem yog ib tug discontinuous theem nyob rau hauv composites. Ntxiv mus, lub matrix theem ua raws li tus binder los tuav ua ke cov ntaub ntawv dispersed, thaum lub dispersed theem ua raws li cov khoom faib los muab bulk lossis reinforcement.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm matrix thiab cov theem tawg hauv cov khoom sib xyaw hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Matrix vs Dispersed Phase in Composites
Theem matrix hauv cov khoom sib xyaw yog lub cev txuas ntxiv uas zoo li muab cov khoom sib xyaw thiab muab daim ntawv ntau rau cov khoom sib xyaw. Lub dispersed theem nyob rau hauv composites yog lub discontinuous theem ntawm composite khoom, uas txiav txim siab lub internal qauv. Yog li ntawd, qhov sib txawv tseem ceeb ntawm matrix thiab dispersed theem nyob rau hauv composites yog hais tias lub matrix theem yog ib tug tas mus li theem, whereas lub dispersed theem yog ib tug discontinuous theem nyob rau hauv composites.
