Kusiyana Kwakapangidwe ndi Kupanga Pakati pa Ulusi Wosalekeza wa Filament Mat ndi Chopped Strand Mat

Zida zolimbitsa magalasi, mongaContinuous Filament Mat (CFM)ndichopped strand mat (CSM), amagwira ntchito yofunika kwambiri popanga zinthu zambiri. Ngakhale onsewa amagwira ntchito ngati zida zoyambira pamachitidwe opangira utomoni, mawonekedwe awo amapangidwe ndi njira zopangira zimasiyana kwambiri, zomwe zimapangitsa kuti pakhale zopindulitsa pazogwiritsa ntchito mafakitale.

1. Fiber Architecture ndi Manufacturing Process

Makasi opitilira filament amapangidwa ndimatumba opangidwa mwachisawawa koma osasokoneza, omangidwa pamodzi pogwiritsa ntchito zomangira mankhwala kapena njira zamakina. Chikhalidwe chosalekeza cha ulusi chimatsimikizira kuti mphasa imasunga zingwe zazitali, zosasweka, kupanga maukonde ogwirizana. Kukhazikika kwapangidwe kumeneku kumapangitsa kuti ma filament apitirire kupirira kupsinjika kwamakina bwino, kuwapangitsa kukhala abwino kwahigh-pressure akaumba njira. Mosiyana ndi zimenezi, mphasa wodulidwa wodulidwa amakhala ndizigawo zazifupi, za discrete fiberkugawidwa mwachisawawa ndi kumangirizidwa ndi zomangira za ufa kapena emulsion. Ulusi wolekanitsa umapangitsa kuti pakhale kukhazikika kokhazikika, komwe kumayika patsogolo kumasuka komanso kusinthasintha kuposa mphamvu yaiwisi.

2. Mechanical and Processing Performance  

Kulumikizana kosalekeza kwa fiber mu CFM kumaperekaisotropic makina katundundi mphamvu yowonjezereka komanso kukana kutsukidwa kwa utomoni. Izi zimapangitsa kuti ikhale yoyenera kwambirinjira zotsekera nkhungumonga RTM (Resin Transfer Molding) kapena SRIM (Structural Reaction Injection Molding), kumene utomoni uyenera kuyenda mofanana pansi pa kupanikizika popanda kusuntha ulusi. Kuthekera kwake kukhalabe okhazikika pa nthawi ya kulowetsedwa kwa utomoni kumachepetsa zolakwika mu ma geometries ovuta. Chopped strand mat, komabe, amapambanamofulumira utomoni machulukitsidwendi kufanana ndi mawonekedwe osakhazikika. Ulusi waufupiwo umalola kunyowa mwachangu komanso kutulutsa mpweya wabwino panthawi yoyika manja kapena kuumba, zomwe zimapangitsa kukhala chisankho chokonda kugwiritsa ntchito zinthu zosavuta komanso zotsika mtengo ngati bathware kapena mapanelo amagalimoto.

3. Ubwino Wogwiritsa Ntchito

Makatani opitilira filament amapangidwirakompositi yogwira ntchito kwambirizomwe zimafuna kulimba, monga zida zamlengalenga kapena masamba a turbine yamphepo. Kukana kwawo kwa delamination ndi kukana kutopa kwakukulu kumatsimikizira moyo wautali pansi pa katundu wozungulira. Komano, mphasa zodulidwa zimakonzedwa bwinokupanga zochulukakumene liwiro ndi zinthu zakuthupi zimafunikira. Makulidwe awo a yunifolomu komanso kuyanjana ndi ma resin osiyanasiyana amawapangitsa kukhala abwino popanga mapepala (SMC) kapena kupanga mapaipi. Kuphatikiza apo, zingwe zodulidwa zimatha kusinthidwa kukhala zolimba komanso zomangira kuti zigwirizane ndi machiritso, zomwe zimapangitsa kuti opanga azisinthasintha.

Mapeto

Chisankho pakati pa mphasa wopitilira ndi zingwe zodulidwa zimatengera kusanja zomwe zimafunikira pamapangidwe, liwiro la kupanga, ndi mtengo wake. Makatani opitilira apo amapereka mphamvu zosayerekezeka zamapangidwe apamwamba, pomwe ma strand odulidwa amaika patsogolo kusinthasintha komanso chuma pakugwiritsa ntchito kwambiri.
