Cov khoom siv iav fiber ntau, xws liNruam filament lev (CFM)thiabchopped strand lev (CSM), ua lub luag haujlwm tseem ceeb hauv kev tsim khoom sib xyaw. Txawm hais tias ob qho tib si ua cov ntaub ntawv tseem ceeb rau cov txheej txheem resin-raws li, lawv cov yam ntxwv ntawm cov txheej txheem thiab cov txheej txheem ntau lawm sib txawv, ua rau muaj txiaj ntsig zoo hauv kev lag luam.
1. Fiber Architecture thiab Manufacturing txheej txheem
Nruam filament lev yog tsim los ntawmrandomly oriented tab sis uninterrupted fiber bundles, khi ua ke siv tshuaj binders los yog mechanical txoj kev. Qhov xwm txheej tsis tu ncua ntawm cov fibers kom ntseeg tau tias cov lev khaws cia ntev, tsis tawg strands, tsim kom muaj kev sib koom ua ke. Qhov kev ncaj ncees ntawm cov qauv no tso cai rau cov ntaub nplaum txuas ntxiv kom tiv thaiv kev ntxhov siab ntawm cov neeg kho tshuab zoo dua, ua rau lawv zoo tagnrho rauhigh-pressure molding txheej txheem. Nyob rau hauv sib piv, tws strand lev muajluv, discrete fiber ntau nturandomly faib thiab sib txuas nrog cov hmoov los yog emulsion binders. Cov fibers tsis tu ncua ua rau cov qauv tsis tshua muaj zog, uas yog qhov tseem ceeb ntawm kev tuav tau yooj yim thiab yoog raws li raw lub zog.
2. Mechanical thiab Processing Performance
Kev sib txuas ntawm fiber ntau txuas ntxiv hauv CFM muabisotropic mechanical zognrog kev txhim kho tensile lub zog thiab ua haujlwm rau resin washout. Qhov no ua rau nws tshwj xeeb tshaj yog haum raukaw-pwm cov txheej txheemzoo li RTM (Resin Transfer Molding) los yog SRIM (Structural Reaction Injection Molding), qhov twg cov resin yuav tsum ntws sib npaug hauv qhov siab yam tsis muaj kev hloov pauv fibers. Nws lub peev xwm los tswj qhov kev ruaj ntseg ntawm qhov ntev ntawm cov resin infusion txo qhov tsis xws luag hauv cov geometry nyuaj. Chopped strand lev, txawm li cas los xij, ua tau zoo hauvceev resin saturationthiab conformability rau irregular shapes. Cov fibers luv luv tso cai rau cov ntub dej tawm sai dua thiab tso cua zoo dua thaum lub sij hawm tso tes los yog qhib molding, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv yooj yim, nqi-sensitive xws li cov khoom siv da dej lossis cov khoom siv tsheb.
3. Application-Specific Advantages
Nruam filament mats yog engineered rauhigh-kev ua tau zoo compositesyuav tsum tau durability, xws li aerospace Cheebtsam los yog cua turbine hniav. Lawv tsis kam mus rau delamination thiab superior qaug zog tiv thaiv kom lub neej ntev nyob rau hauv cyclic loads. Chopped strand mats, ntawm qhov tod tes, yog optimized rauntau lawmqhov twg ceev thiab cov khoom efficiency tseem ceeb. Lawv cov tuab tuab thiab sib haum nrog ntau hom resins ua rau lawv zoo tagnrho rau cov ntawv molding compound (SMC) lossis cov yeeb nkab tsim. Tsis tas li ntawd, chopped strand mats tuaj yeem hloov kho nyob rau hauv qhov ntom ntom thiab khi hom kom haum rau kev kho mob tshwj xeeb, muab qhov yooj yim rau cov tuam txhab.
Xaus
Qhov kev xaiv ntawm qhov nruam filament lev thiab tws strand mats hinges ntawm kev sib npaug ntawm cov qauv xav tau, ntau lawm ceev, thiab tus nqi. Nruam filament mats muab lub zog tsis sib haum xeeb rau cov khoom sib xyaw ua ke, thaum chopped strand lev yog qhov tseem ceeb ntawm kev siv ntau yam thiab kev lag luam hauv cov ntawv ntim siab.
