Ntev Fiber Composite vs Short Fiber Composite: Nkag siab qhov txawv
Composites tau dhau los ua cov khoom siv nrov ntawm kev xaiv thoob plaws ntau lub lag luam, muab lawv cov khoom tshwj xeeb uas muaj ntau yam txiaj ntsig xws li kev txhim kho lub zog, khov kho, txo qhov hnyav, thiab ntau dua. Cov khoom sib xyaw no suav nrog ntau yam kev sib txuas ntawm fibers, resins, thiab additives nyob ntawm daim ntawv thov. Txawm li cas los xij, cov fibers siv hauv cov khoom sib txawv tuaj yeem sib txawv ntawm qhov ntev, yog li ua rau kev faib cov khoom sib xyaw ua ob hom - ntev fiber ntau sib xyaw thiab luv fiber ntau sib xyaw.
Ntev Fiber Composites:
Ntev fiber ntau sib xyaw feem ntau suav nrog cov fibers txuas ntxiv lossis tsis txuas ntxiv uas ntev dua li qhov ntev ntawm cov khoom sib txuas luv. Cov fibers no feem ntau sib raug zoo, nyob nruab nrab ntawm 50-60 feem pua ntawm qhov ntim, nrog rau cov resin ntim cov khoob hauv nruab nrab. Cov fibers ntev muab kev nruj dua, cov khoom siv kho tshuab, thiab lub zog. Cov khoom sib xyaw no tau siv dav hauv kev siv xws li cov khoom siv tsheb, aerospace, thiab cov khoom ua si. Ntev fiber ntau ua kom pom cov khoom tensile zoo, nrog rau siab tawv thiab lub zog uas tiv taus cov kev siv thauj khoom.
Short Fiber Composites:
Cov fibers luv luv, ntawm qhov tod tes, feem ntau muaj cov fibers uas luv dua li cov fiber ntau ntev. Cov fibers no feem ntau random thiab thaj tsam ntawm 5-10 feem pua ntawm qhov ntim, nrog rau cov resin nyob rau qhov chaw seem. Cov khoom sib xyaw no tau siv dav hauv kev siv xws li hluav taws xob thiab hluav taws xob vaj tsev, cov khoom siv, thiab cov kav dej. Tab sis luv fiber ntau composites tsis muaj zog thiab nruj ntawm ntev fiber ntau composites.
Qhov txawv ntawm qhov ntev thiab luv fibers yog dab tsi?
Qhov sib txawv ntawm cov fiber ntau ntev thiab luv fiber ntau sib xyawtuaj yeem nkag siab txog lawv cov khoom thiab cov yam ntxwv ntawm lawv cov fibers. Ntev fibers muab siab modulus, siab zog, thiab zoo kev nyuaj siab kis tau tus mob muaj peev xwm, ua rau lawv haum rau load-bearing daim ntaub ntawv.Thiab luv fibers composite, raws li lawv random orientation, pom tsawg nam piv tau nyob rau hauv ib tug qis modulus, txwv lawv daim ntawv thov rau cov uas tsis yog-load bearing Cheebtsam.
Hauv kev xaus, thaum luv fiber ntau composites tsis tuaj yeem muaj qhov nruj txaus, tensile lub zog, flexural zog / modulus ntawm kev ua haujlwm ntawm cov khoom siv, cov khoom siv fiber ntau ntev yuav yog qhov kev xaiv tsim nyog rau kev siv cov khoom siv uas yuav tsum tau muaj zog thiab nruj txawm tias hloov cov hlau rau lub teeb. hnyav los yog txo tus nqi.
