Indlela i-FRP ephakamisa ngayo i-Pole Vaulting ukuya kwiNew Heights

Ifiziksi esemva komnyhadala wepali yevault ibandakanya ukudibana okuntsokothileyo kwamandla embaleki kunye ne-pole recoil. Njengoko umtsi utsiba ezantsi kumgaqo weenqwelo-moya ngesantya esiphezulu, batyala ipali ebhetyebhetye kwibhokisi, iphinda iqondise isantya esithe tyaba sibheke phezulu njengoko ipali igoba. Ixesha "lokunduluka" ngokuchanekileyo libalulekile-kwangethuba kakhulu, kwaye isibonda asiyi kubonelela ngokwaneleyo; kade kakhulu, kwaye amandla agcinwe ngeelastiki ayachithakala endaweni yokubonisa imbaleki esibhakabhakeni.

Njengoko iinjineli zizabalazela ukwaphula imiqobo yokusebenza, ziphengulula nzulu kwizinto ezinokulinganiswa njengokuqina kwepali, ixesha lokubuyisela, kunye nokubuya kwamandla. Ukudibana phakathi kobuchule bembaleki kunye nezixhobo zabo kunika umngeni onomdla wobunjineli. Uphando olunzulu lwezenzululwazi kunye novavanyo lungena ekuphuculeni iipali zokutsiba eziphezulu ukuhambisa amandla ngokufanelekileyo kangangoko.

Iinjineli zizabalazela ukufumana ulungelelwano olufanelekileyo lwamandla, ukuguquguquka, ukuqina, kunye nokukhaphukhaphu kwezixhobo zepali. I-Fiberglass reinforced plastic (FRP) ngumgqatswa ogqwesileyo, ohlangabezana nezi mfuno ngempumelelo. Le ngqungquthela idibanisa ifayibha yeglasi yokuqina kunye nokuqina kunye neplastiki ye-polymer matrix, izisa ukuguquguquka. Isiphumo siyinto eyomeleleyo kodwa enwebekayo evuthiweyo ukuze iphuculwe ngakumbi.

I-FRP ibonelela ngamandla aphezulu-kubunzima bomlinganiselo kunezixhobo zangaphambili ezifana neenkuni, i-bamboo, kunye nokwahluka kwe-fiberglass yokuqala. Imisonto yeglasi ye-macrostructure inika amandla, ngelixa i-polymer matrix yeplastiki isasaza ngokulinganayo amandla omthwalo kuwo wonke. I-FRP inokugoba kwaye yolule ukugcina amandla amakhulu ngaphambi kokuba ibuyele ngokukhawuleza ngokwaneleyo ukubuya kwamandla amaninzi.

Ukuqina kungenye inzuzo-izibonda ze-FRP zigcina ukusebenza okuhambelanayo kumawaka emijikelezo yokugoba. Bagcina ngcono ukuguquguquka okulungisiweyo kunye nokuqina okwenzelwe iimbaleki ezithile kwiminyaka yoqeqesho kunye nokhuphiswano. Ukulungiswa okuqhubekayo kubandakanya iintlaka zeplastiki eziphambili kunye nokuqhelaniswa kwefiber echanekileyo.

Amandla akhoyo e-FRP ukuhambisa iipali kunye neendibaniselwano ezingazange zibonwe ngaphambili zamandla, ukuqina, ukomelela, kunye nobunzima. Olu lungelelwaniso lunokubonelela ngomda wokhuseleko olunqwenelwa ziinjineli kunye nokuphendula okulungiselelweyo okuvumela iivaulters ezikumgangatho ophezulu ukuba zinyuke ngakumbi. Inkqubela phambili kwisayensi yezinto eziphathekayo kunye nobunjineli be-nano bematriki ehlanganisiweyo ephezulu inika ikamva elichulumancisayo leplastiki eyomelezwe ngefiberglass kwibala le-pole vault.
