1. Mphamvu yakuli
Mphamvu yayikulu ndiyotsekera kwambiri zomwe zingakhalepo musanatambasule. Zinthu zina zopanda ulemu zimasiyanitsa pamaso pa mpweya, komaKevlar® (Amimidi) ulusi, ulusi wa kaboni, ndipo ulusi wa e-wagalasi ndi wopanda mphamvu ndipo wotupa sungunuka pang'ono. Mphamvu ya Tunsile imayezedwa ngati mphamvu iliyonse (pa kapena pascals).

2. Kuchulukitsa ndi kuchuluka kwamphamvu
Poyerekeza ndalama za zinthu zitatuzi, kusiyana kwakukulu mu ulusi womwewo ungawonekere. Ngati zitsanzo zitatu zofanana ndendende ndi kunenepa zimapangidwa, zimawoneka mwachangu kuti ulusi wa Kevlar® ndiwopepuka kwambiri, wokhala ndi kaboni pang'ono ndiUlusi wa e -galasizolemera kwambiri.

Moderos wachichepere ndi muyeso wa kuuma kwa zinthu zotsekemera ndipo ndi njira yofotokozera zinthu. Amatanthauziridwa ngati chiwerengero cha unoxial (mbali imodzi) kupsinjika kwa pakati (kuphatikizika komweko). HAMUUS PMUDUS = Kupsinjika / Kupsinjika, zomwe zikutanthauza kuti zinthu zomwe zili ndi moddahus yochepa kwambiri ndi zotupa kuposa zomwe zili ndi ana otsika ang'ono.
Kuuma kwa mpweya, kevlar ®, ndipo ulusi wagalasi umasiyana kwambiri. Mitundu ya carbon ili yolimba ngati ulusi wa Aaramidi ndi kasanu kuposa ulusi wagalasi. Kupsinjika kwa owuma kwambiri cha kagalimoto cha kagalimoto champhamvu ndikuti kumayenera kukhala opanda phokoso kwambiri. Pakalephera, sizimakonda kuwonetsa zovuta kapena kusinthitsa.

Ally onse a Kevlar® ndi Carbon Arbon amalimbana ndi kutentha kwambiri, ndipo kapena malo osasungunuka. Zipangizo zonsezi zagwiritsidwa ntchito poteteza zovala ndi nsalu zosagwira moto. Fiberglass pamapeto pake amasungunuka, komanso amalimbana ndi kutentha kwambiri. Zachidziwikire, ulusi wamagalasi womwe umagwiritsidwa ntchito mu nyumba zitha kuwonjezera moto.
Carbon mbiti ndi kevlar ® imagwiritsidwa ntchito popanga zotchinga moto woteteza kapena kuwotcha zofunda kapena zovala. Magolovesi a Kevlar nthawi zambiri amagwiritsidwa ntchito mu malonda a nyama kuti ateteze manja pogwiritsa ntchito mipeni. Popeza ulusiwo suzigwiritsa ntchito pawokha, kukana kutentha kwa matrix (nthawi zambiri epoxy) ndikofunikanso. Akatenthedwa, epoxy amasintha msanga.

5. Zochita zamagetsi
Mitundu ya kaboni imayambitsa magetsi, koma Kevlar® ndigalasiOsamachita.Kevlar ® imagwiritsidwa ntchito pokoka mawaya m'matumba ophatikizira. Ngakhale sizimachita zamagetsi, zimatenga madzi ndi madzi zimapangitsa magetsi. Chifukwa chake, chophimba chamadzimadzi chofunda chiyenera kugwiritsidwa ntchito ku Kevlar mu ntchito zotere.

6. UV kuwonongeka
Ulusi wa Aaramidiimasokoneza dzuwa ndi malo apamwamba a UV. Mitundu ya kaboni kapena galasi siyosamala kwambiri za radiation ya UV. Komabe, materics ena wamba monga epoxy amasudzulidwa padzuwa komwe iyo idzakhala yoyera ndikutaya mphamvu. Polyesterter ndi vanyl este amagonjetsedwa ndi UV, koma ofooka kuposa epoxy.

7. Kukaniza kutopa
Ngati gawo likuyang'aniridwa mobwerezabwereza, pamapeto pake limalephera chifukwa cha kutopa.Kabonindizovuta kumva kutopa ndipo imalephera kulephera, pomwe Kevlar® imalephera kutopa. Fiberglass ili kwinakwake pakati.

8.. Abrasion Kukana
Kevlar® ikugwirizana kwambiri ndi Abrasion, zomwe zimapangitsa kuti zikhale zovuta kudula, ndipo chimodzi mwazomwe zimagwiritsidwa ntchito limodzi ndi magolovesi oteteza madera omwe manja angadulidwe ndi galasi kapena pomwe masamba akuthwa amagwiritsidwa ntchito. Mitundu ya kaboni ndi galasi silikugwirizana.

9. Kukaniza kwamankhwala
Ulusi wa AaramidiAmakhala ndi chidwi ndi ma acid a acid, zitsulo ndi othandizira ena oxidizing (mwachitsanzo, sodium hypochlorite), zomwe zingayambitse kuchepa kwa mazemba. Chikwangwani wamba cha chlorine (mwachitsanzo Clorox®) ndi hydrogen peroxide silingagwiritsidwe ntchito ndi Kevlar®. Mwala wa oxygen (mwachitsanzo, sodium yothandizana ndi yopindulitsa popanda kuwononga ulusi wa Aaramidi.

10. Kugwirizanitsa thupi
Kuti alowe mu ulusi wa kaboni, kevlar ® ndigalasi kuti agwire bwino, ayenera kukhazikitsidwa m'malo mwake matrix (nthawi zambiri a epoxy). Chifukwa chake, kuthekera kwa epoxy kugwirizanika ku ulusi wosiyanasiyana ndikofunikira.
Onse kaboni ndipoulusi wagalasiItha kumamatira kwa epoxy, koma kumera wa ku Aaramidi sikulimba monga momwe mungafunire, ndipo zotsatsa izi zimapangitsa kuti kulowetsedwa kwamadzi kuchitika. Zotsatira zake, kufooketsa komwe kutsanzira kwa Aaramidi kumatha kuthira madzi, kuphatikiza ndi zomata zosafunikira ku epoxy, kumatanthauza kuti ngati mawonekedwe a Kevlar® amatha kulowa m'madzi ndikuchepetsa mphamvu.

11. Mtundu ndi Kuluka
Aramike ndi wowala wagolide mdera lake lachilengedwe, amatha kukhala achikuda ndipo tsopano amabwera m'mithunzi yambiri yabwino. Fiberglass imabweranso m'mitundu yakale.Kaboninthawi zonse imakhala yakuda ndipo imatha kuphatikizidwa ndi aramid achikuda, koma silingakhale odzikuza.
