Ulusi wa Aramid, yomwe imadziwikanso kuti aramid, ndi ulusi wopangidwa womwe umadziwika ndi mphamvu zake zapadera, kukana kutentha, komanso kukana kukwawa. Zinthu zodabwitsazi zasintha kwambiri mafakitale kuyambira ndege ndi chitetezo mpaka magalimoto ndi zinthu zamasewera. Chifukwa cha mawonekedwe awo apadera, ulusi wa aramid wakhala chinthu chodziwika bwino chomwe chimafuna magwiridwe antchito apamwamba komanso kulimba.

Chimodzi mwa zinthu zofunika kwambiri zaulusi wa aramidndi chiŵerengero chake champhamvu kwambiri pakati pa kulemera ndi mphamvu. Izi zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zinthu zopepuka komanso zamphamvu kwambiri. Mu makampani opanga ndege, ulusi wa aramid umagwiritsidwa ntchito popanga zinthu za ndege monga mapiko, mapanelo a fuselage ndi masamba a rotor. Mphamvu yake yolimba komanso kulemera kwake kochepa zimapangitsa kuti ikhale chinthu chamtengo wapatali chowongolera magwiridwe antchito ndi magwiridwe antchito a ndege.

Kuphatikiza apo, kukana kutentha kwaulusi wa aramidZimasiyanitsa ndi zipangizo zina. Zimatha kupirira kutentha kwambiri popanda kusokoneza kapangidwe kake, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo otentha kwambiri, monga popanga zovala zoteteza ozimitsa moto ndi ogwira ntchito m'mafakitale. Kuphatikiza apo, kukana kwake kukanda kumapangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito komwe kulimba ndikofunikira, monga kupanga ma vesti a ballistic ndi zipewa za asilikali ndi apolisi.

Makampani opanga magalimoto akuyambanso kugwiritsa ntchito ulusi wa aramid m'zigawo zosiyanasiyana, kuphatikizapo ma brake pad, ma clutch plates ndi matayala. Kutha kwake kupirira kutentha kwambiri ndi kukangana kumapangitsa kuti ikhale chinthu choyenera kwambiri chowongolera magwiridwe antchito ndi moyo wautali wa zigawo zofunika kwambiri zamagalimoto izi. Kuphatikiza apo, mawonekedwe ake opepuka amathandizira kukonza kugwiritsa ntchito mafuta moyenera ndikuchepetsa kulemera konse kwa magalimoto, mogwirizana ndi nkhawa zamakampani pankhani yokhazikika komanso kuwononga chilengedwe.

Mu dziko la zinthu zamasewera, ulusi wa aramid ndi wotchuka kugwiritsidwa ntchito pazinthu monga zingwe za tenisi, matayala a njinga ndi zida zodzitetezera kwambiri pamasewera. Ochita masewera ndi okonda masewera amayamikira kuthekera kwa zinthuzo kukulitsa magwiridwe antchito ndikupereka chitetezo chapamwamba, kaya pabwalo la tenisi kapena panthawi yokwera njinga mwachangu. Kulimba ndi kudalirika kwa ulusi wa aramid kumapangitsa kuti ikhale chisankho chokopa kwa opanga omwe akufuna kupanga zida zamasewera zogwira ntchito bwino.

Kuwonjezera pa ntchito m'mafakitale achikhalidwe,ulusi wa aramidamagwiritsidwanso ntchito mu ukadaulo watsopano komanso zinthu zatsopano. Kugwiritsa ntchito kwake popanga zikwama zotetezera zipangizo zamagetsi monga mafoni ndi mapiritsi kukuwonetsa kusinthasintha kwake komanso kusinthasintha kwake kuti zikwaniritse zosowa za ogula amakono. Kukana kwa zinthuzo komanso kulimba kwake kumawonjezera phindu ku zida zamagetsi zomwe ogula amagwiritsa ntchito, ndikuwonetsetsa kuti zidazi zimakhala zotetezeka komanso zokhalitsa.

Pamene kufunikira kwa zipangizo zogwirira ntchito bwino kukupitirira kukula m'mafakitale osiyanasiyana, kusinthasintha kwa aramid fiber ndi kudalirika kwake kumapangitsa kuti ikhale chinthu chosankhidwa ndi opanga ndi mainjiniya. Kuphatikiza kwake kwapadera kwa mphamvu, kukana kutentha komanso kulimba kumapangitsa kuti ikhale patsogolo pakupanga zinthu zatsopano, zomwe zimapangitsa kuti pakhale kupita patsogolo pakupanga zinthu ndi magwiridwe antchito m'magawo osiyanasiyana.

Ponseponse,ulusi wa aramidkusonyeza mphamvu yosintha ya zipangizo zamakono popanga tsogolo la mafakitale. Makhalidwe ake apadera amachithandiza kusintha miyezo ya mphamvu, kukana kutentha ndi kulimba, zomwe zimapangitsa kuti chikhale chofunikira kwambiri pakupanga zinthu zogwira ntchito bwino. Pamene kafukufuku ndi chitukuko cha sayansi ya zipangizo zikupitirira kupita patsogolo, ulusi wa aramid umakhalabe chizindikiro cha luso ndi ubwino, kuyendetsa patsogolo m'munda uliwonse ndikukankhira malire a zomwe zingatheke.
