Composite cov ntaub ntawv, lawv cov khoom thiab daim ntawv thov

Qhov no xyoo pua, by analogy nrog ib tug bronze los yog muaj hnub nyoog hlau, peb yuav confidently yuav hu ua lub xyoo pua ntawm puas cov ntaub ntawv. Lub rov tshwm sim ntawm lub sij hawm yog hais txog mus rau nruab nrab ntawm lub xyoo pua xeem, tab sis heev tswvyim yog tsis tshiab - siv ob peb ua ke ntawm ntaub ntawv sib txawv siv nyob rau hauv kev tsim kho ntawm lub tsev builders ntawm ancient Babylon thiab Rome, cov masters ntawm ancient Greece thiab Moscow architects. Nyob rau hauv tas li ntawd, kuaj ntawm puas ntaub ntawv nyob rau hauv ib tug ntau yam ntawm qhov nws tus kheej - ib tug pob txha, ntoo, zoo li ntawm cov tsiaj, thiab lwm yam Composite ntaub ntawv muaj zoo zoo nta thiab txaus nyiam tsos.

Cov ntaub ntawv no yog tsim los ntawm cov ob peb yam: ib lub hnab yas puag, uas yog hu ua tus matrix thiab fillers uas tso cai rau muab ib tug sib tov ntawm pib thawj zog tsis Ameslikas hais rau nws. Ib tug feature ntawm tus qhab ntaub ntawv yog lub xub ntiag ntawm ib thaj tsam ntawm lub Cheebtsam, uas yog hu ua theem.

Zus tau tej cov no cov ntsiab aims ntawm cov creation ntawm cov khoom tshiab uas yog lub siab tshaj plaws zoo tsim nyog rau txoj kev loj hlob ntawm cov niaj hnub science thiab ntau lawm. Mus cuag tej yam tshwm sim siv qhov kev hloov nyob rau hauv lub ratio ntawm matrix thiab fillers, tshwj xeeb cov neeg ua hauj koom siv. Attendance tseem ceeb nyob rau hauv qhov siv thiab ua composites muaj ib tug kev kho hais nyob rau hauv cov khoom, lawv txiav txim nyob rau hauv kev sib raug zoo rau txhua tus lwm yam thiab nyob rau hauv lub npaj kev taw qhia ntawm load tej yam. Lub siab dua tus qhab zog, lub siab thiaj muaj nws cov qauv.

Niaj hnub no, lub sij hawm yog hais txog tag nrho cov composite ntaub ntawv ntau yam ntawm tus txiv neej-ua khoom, muab hais tias lawv ntau lawm txheej txheem raws li tej ntsiab cai ntawm kev tsim composites. Ib tug ntau yam pauv loj nce nyob rau hauv kev txaus siab nyob rau hauv txoj kev loj hlob thiab zus tau tej cov ntaub ntawv tshiab muaj txhawb rau mismatch ntawm tsoos designs yuav tsum niaj hnub engineering xyaum.

Yuav ua li cas muaj composites

Raws li ib tug matrix nyob rau hauv lawv cov kev siv thiab feem ntau siv: MAAs, hlau, polymers thiab ceramics. Fillers li yuav ua tau tej yam ntuj tso los dag tshuaj muaj lub fiber, ib daim ntawv, ib tug dispersed, loj loj ntaub ntawv (nyuam qhuav tau daim microparticulated thiab nanoparticles muaj tau siv).

Multicomponent puas ntaub ntawv muab faib ua: ib tug hybrid, xws li nyob rau hauv nws muaj pes tsawg leeg txawv fillers thiab polimatrichnye combining nyob rau hauv ib tug cov ntaub ntawv uas ob peb matrices.

Teb daim ntawv thov ntawm puas ntaub ntawv

Vim hais tias, tsim composites, txhob txwm tshaj tawm muab lawv sib txawv zog, thiab lub Scope ntawm lawv daim ntawv thov yog yuav tsum tau uas nws kim heev. Vim nws cov qauv thiab muaj pes tsawg leeg, composites yuav ua tau lub xov tooj cua-absorbing cov khoom los yog yuav radiotransparent, lawv tau yooj yim tiv nrog lub thermal tiv thaiv ntawm chaw noj. Composite ntaub ntawv no yog siv raws li ib tug ruaj thiab txhim khu kev qha kev tsim kho cov ntaub ntawv thiab zoo nkauj hniav finishes. Nws yog ib qhov nyuaj rau overestimate tau ntawm kev loj hlob thiab kev txhim kho ntawm ntau lawm thiab technology, uas enables cov kev siv ntawm composites nyob rau hauv electronics, tshuaj, kev lag luam, kev ua si, kos duab.

Tam sim no koj paub ntau yam txog dab tsi yog ib tug ntau lawm ntawm puas ntaub ntawv!
