I-FRP(I-Fiber Reinforced Polymer)

Ukwethulwa Kokuphrinta kwe-FRP 3D

I-Fiber Reinforced Polymer (FRP) iyinhlanganisela yezinto ehlanganisa i-polymer matrix eqiniswe ngemicu. Le nto esebenza ngezindlela eziningi ihlanganisa amandla kanye nokuqina kwamafayibha—njengengilazi, ikhabhoni, noma imicu ye-aramid—nezakhiwo ezingasindi nezimelana nokugqwala zamareyini e-polymer njenge-epoxy noma i-polyester. I-FRP ithola izinhlelo zokusebenza ezisabalele kuzo zonke izimboni ezihlukene ngenxa yezakhiwo zayo ezihlukile zemishini, okuhlanganisa isilinganiso esiphezulu samandla nesisindo, ukuqina, kanye nokuguquguquka komklamo. Ukusetshenziswa okuvamile kufaka ukuqinisa izakhiwo ezakhiweni, ukulungiswa kwamabhuloho, izingxenye ze-aerospace, izingxenye zezimoto, ukwakhiwa kolwandle, kanye nemishini yezemidlalo. Amandla okwenza izinhlanganisela ze-FRP zihambisane nezidingo ezithile zokusebenza zizenza ukukhetha okuthandwayo kubunjiniyela besimanje kanye nezinqubo zokukhiqiza.

Nansi indlela esebenza ngayo.

I-1.Ukukhethwa Kwe-Fiber: Kuye ngezidingo zohlelo lokusebenza, ama-fibers akhethwa ngokusekelwe ezintweni zabo zemishini. Isibonelo, ama-carbon fibers anikeza amandla aphezulu nokuqina, okuwenza afanelekele ukusetshenziswa kwe-aerospace nezimoto, kuyilapho imicu yengilazi inikeza amandla amahle nokusebenza kahle kwezindleko zokuqiniswa kwesakhiwo okuvamile.

2.I-Matrix Material: I-matrix ye-polymer, ngokuvamile esesimweni se-resin, ikhethwa ngokusekelwe ezintweni ezifana nokuhambisana namafayibha, izici zomshini ezifiswayo, nezimo zemvelo inhlanganisela ezovezwa kuzo.

3.I-Composite Fabrication: Imicu igxiliswa nge-resin ewuketshezi bese ibunjwa ibe yisimo oyifunayo noma isetshenziswe njengezingqimba esikhunjeni. Le nqubo ingenziwa ngamasu afana nokubeka isandla, ukugoqa intambo, i-pultrusion, noma i-automated fiber placement (AFP) kuye ngobunkimbinkimbi nobukhulu bengxenye.

I-4.Ukuphulukisa: Ngemva kokubunjwa, i-resin ithola ukwelashwa, okubandakanya ukusabela kwamakhemikhali noma isicelo sokushisa ukuze kuqiniswe futhi kuqiniswe izinto ezihlanganisiwe. Lesi sinyathelo siqinisekisa ukuthi imicu iboshwe ngokuvikelekile ngaphakathi kwe-polymer matrix, yakha isakhiwo esiqinile nesihlangene.

5.Ukuqedwa kanye Nokucubungula Ngemva Kokucubungula: Uma seselaphekile, inhlanganisela ye-FRP ingase ibhekane nezinqubo zokuqeda ezengeziwe ezifana nokusikwa, ukwenza isihlabathi, noma ukuhlanganisa ukuze kuzuzwe ukuphela kwendawo oyithandayo kanye nokunemba kobukhulu.
