Hunhu hwemuviri hwezvinhu zvakaumbwa zvinotongwa nefibers.Izvi zvinoreva kuti kana resin nemafibhi zvabatanidzwa, zvimiro zvavo zvakafanana neaya ega ega.Yedzo data inoratidza kuti fiber-yakasimbiswa zvinhu ndizvo zvinotakura zvakawanda zvemutoro.Nokudaro, kusarudzwa kwejira kunokosha kana uchigadzira zvivako zvakasanganiswa.

Tanga maitiro nekusarudza rudzi rwekusimbisa inodiwa muprojekiti yako.Vagadziri vemhando vanogona kusarudza kubva pazvinhu zvitatu zvakajairika zvekusimbisa: girazi faibha, kabhoni faibha uye Kevlar® (aramid fiber).Girazi faibha dzinowanzoita sarudzo-yechinangwa, nepo kabhoni faibha inopa kuomarara kwakanyanya uye Kevlar® yakakwirira abrasion kuramba.Ramba uchifunga kuti machira emhando anogona kusanganiswa mumalaminates kuti aumbe mahybrid stacks ane mabhenefiti eanopfuura chinhu chimwe.

Kana uchinge wasarudza pamusoro pemachira ekuunganidza, sarudza huremu uye weave style inoenderana nezvido zvebasa rako.Iyo yakareruka pairi yejira, zviri nyore kudonhedza pamusoro penzvimbo dzakakomberedzwa zvakanyanya.Lightweight inoshandisawo resin shoma, saka iyo laminate yese ichiri kureruka.Sezvo machira achiwedzera kurema, anova asingachinjiki.Huremu huri pakati nepakati hunochengeta kuchinjika kwakaringana kuvhara macontours mazhinji, uye anobatsira zvakanyanya kusimba rechikamu.Iwo ane hupfumi zvakanyanya uye anogadzira akasimba uye akareruka zvinhu zvemotokari, zvemugungwa uye maindasitiri application.Yakarukwa rovings inorema inosimbisa inowanzoshandiswa mukuvaka ngarava nekugadzira mold.

Marukwa ejira anoonekwa sepatani kana manyorerwo aro.Sarudza kubva kune matatu akajairwa zvitaera zvekuruka: plain, satin uye twill.Plain weave styles ndiyo yakachipa uye isinganyanyi kuchinjika, asi inobata pamwe chete zvakanaka kana yakachekwa.Kakawanda kumusoro/pasi kuyambuka shinda kunoderedza kusimba kweiyo plain weave, kunyangwe zvichiri kukwana kune ese asi epamusoro maapplication ekuita.

Satin uye twill weave zvakapfava uye zvakasimba kudarika plain weave.Mukuruka kwesatin, shinda imwe chete inoyangarara pamusoro pedzimwe shinda nhatu kusvika kunomwe dzozosonerwa pasi peimwe.Murudzi urwu rwakarukwa, shinda inomhanya kwenguva refu, ichichengetedza simba redzidziso refiber.Twill weave inopa kuwirirana pakati pe satin uye plain masitaera, ine inowanzodiwa herringbone embellishment effect.

Tech Tip: Kuwedzera kuchinjika kumucheka, cheka kubva mupumburu pakona ye45-degree.Kana akachekwa nenzira iyi, kunyangwe machira akaomesesa anodonhedza zvirinani pamusoro pesilhouette.

Fiberglass Reinforcement

Fiberglass ndiyo hwaro hweiyo composites indasitiri.Yakave ichishandiswa mune akawanda akaumbwa maapplication kubva kuma1950 uye zvimiro zvayo zvemuviri zvinonzwisiswa.Fiberglass haina huremu, ine mwero tensile uye inomanikidza simba, inogona kutsungirira kukuvara uye cyclic mitoro, uye iri nyore kubata.

Fiberglass ndiyo inonyanya kushandiswa pane zvese zviripo composite zvinhu.Izvi zvinonyanya kukonzerwa nemutengo wakaderera uye zviri pakati nepakati zvinhu zvemuviri.Fiberglass yakanakira mapurojekiti emazuva ese uye zvikamu zvisingade jira refiber rakawedzera simba uye kusimba.

Kuti uwedzere kusimba kwefiberglass, inogona kushandiswa ne epoxy uye inogona kurapwa uchishandisa yakajairwa lamination matekiniki.Yakanakira kunyorera mumaindasitiri emotokari, emugungwa, ekuvaka, emakemikari uye nendege, uye inowanzoshandiswa muzvinhu zvemitambo.

Kevlar® Reinforcement

Kevlar® yaiva imwe yekutanga-yakasimba-simba rekugadzira fibers kuwana kugamuchirwa mune fiber-reinforced plastics (FRP) indasitiri.Composite giredhi Kevlar® haina huremu, ine yakanakisa kusimba kwesimba, uye inoonekwa seyakanyanya kukanganisa uye inodzivirira abrasion.Zvishandiso zvakajairika zvinosanganisira mabhuru akareruka akadai semakayaki uye zvikepe, fuselage mapaneru endege uye midziyo yekumanikidza, magirovhosi asingadzivirirwe, nhumbi dzokurwa nadzo, nezvimwe.Kevlar® inoshandiswa ne epoxy kana vinyl ester resins.

Carbon Fiber Reinforcement

Carbon fiber ine inodarika 90% kabhoni uye ine yakanyanya kusimba yekusimba muindasitiri yeFRP.Muchokwadi, iyo zvakare ine yakanyanya kumanikidza uye inoshanduka simba muindasitiri.Mushure mekugadzirisa, mafiibhi aya anobatana kugadzira kabhoni fiber reinforcement senge machira, tow, nezvimwe.Carbon fiber reinforcement inopa yakakwirira chaiyo kusimba uye kuomarara, uye kazhinji inodhura kupfuura mamwe mafiber reinforcements.

Kuti uwedzere kusimba kwekabhoni fiber, inofanirwa kushandiswa ne epoxy uye inogona kurapwa uchishandisa yakajairwa lamination matekiniki.Yakanakira kunyorera mumotokari, mugungwa uye aerospace, uye inowanzoshandiswa muzvinhu zvemitambo.
