CSM (Wodulidwa Strand Mat) ndikuwomba woluka ndi mitundu yonse ya zida zolimbikitsira zomwe zimagwiritsidwa ntchito popanga mapulasitiki olimba (FRPs), monga ma composites a fiberglass. Amapangidwa kuchokera ku ulusi wagalasi, koma amasiyana pakupanga kwawo, mawonekedwe, ndi ntchito. Nayi kulongosola kwa kusiyanaku:
CSM (Chopped Strand Mat):
- Njira Yopangira: CSM Amapangidwa podula ulusi wagalasi m'zingwe zazifupi, zomwe kenaka zimagawidwa mwachisawawa ndikumanga pamodzi ndi chomangira, chomwe nthawi zambiri chimakhala utomoni, kuti apange mphasa. Chomangiracho chimasunga ulusiwo pamalo ake mpaka chophatikizikacho chachira.
- Fiber Orientation: Ma fiber mu CSM amapangidwa mwachisawawa, zomwe zimapereka isotropic (zofanana mbali zonse) mphamvu ku gulu.
- Mawonekedwe:CSM ili ndi mawonekedwe ngati mphasa, wofanana ndi pepala lochindikala kapena zomverera, zowoneka bwino komanso zosinthika.
- Kusamalira: CSM ndiyosavuta kunyamula ndikuyiyika pamawonekedwe ovuta, kupangitsa kuti ikhale yoyenera kuyika manja kapena kupopera mbewu mankhwalawa.
- Mphamvu: Pamene CSM imapereka mphamvu zabwino, nthawi zambiri sikhala yolimba ngati yoluka chifukwa ulusi wake umadulidwa ndipo sunagwirizane bwino.
- Mapulogalamu: CSM amagwiritsidwa ntchito popanga mabwato, zida zamagalimoto, ndi zinthu zina pomwe chiŵerengero cha mphamvu ndi kulemera chimafunikira.
Woven Roving:
- Njira Yopangira: Kuluka mozungulira amapangidwa ndi kuluka mosalekeza ulusi ulusi wa magalasi mu nsalu. Nsaluzi zimagwirizanitsidwa mumtundu wa crisscross, zomwe zimapereka mphamvu zambiri komanso zowuma potsata ulusi.
- Fiber Orientation: Ma fiber mukuwomba woluka amagwirizana mu njira yeniyeni, zomwe zimabweretsa mphamvu ya anisotropic (yodalira njira).
- Mawonekedwe:Kuluka mozungulira ili ndi mawonekedwe ngati nsalu, yokhala ndi njira yoluka yowoneka bwino, ndipo imakhala yosasinthika kuposa CSM.
- Kusamalira:Woven roving imakhala yolimba kwambiri ndipo imatha kukhala yovuta kwambiri kugwira nayo ntchito, makamaka popanga mozungulira mawonekedwe ovuta. Zimafunika luso lochulukirapo kuti mugone bwino popanda kusokoneza ulusi kapena kusweka.
- Mphamvu: Kuluka mozungulira amapereka mphamvu zapamwamba ndi kuuma poyerekeza ndi CSM chifukwa cha ulusi wopitirira, wogwirizana.
- Mapulogalamu: Woven roving nthawi zambiri amagwiritsidwa ntchito popanga mphamvu komanso kuuma kwakukulu, monga popanga zisankho, ziboliboli zamabwato, ndi magawo azamlengalenga ndi mafakitale amagalimoto.
Mwachidule, kusankha pakatiCSM ndigalasi la fiberglasskuwomba woluka zimadalira zofunikira zenizeni za gawo lophatikizika, kuphatikizapo mphamvu zomwe zimafunidwa, zovuta za mawonekedwe, ndi njira zopangira zomwe zimagwiritsidwa ntchito.
