Mu myaka yashize, habaye iterambere ryihuse rya fibre-ishimangirwaibikoresho bya termoplastique hamwe na thermoplastique isigara nka matrix, kandi hariho kwiyongera mubushakashatsi niterambere ryibi bikoresho bikora cyane kwisi yose. Ibikoresho bya Thermoplastique nibihimbano bikozwe muri polymers ya polymoplastike nka polyethylene (PE), polyamide (PA), polifhenylene sulfide (PPS), polyetherimide (PEI), polyether ketone (PEKK) na polyether ether ketone (PEEK) nka matrix nibindi bitandukanye bikomeza / bidahagarara. fibre (urugero: fibre fibre, fibre ibirahure, fibre aramid, nibindi
Amavuta ya Thermoplastique ashingiye cyane cyane muri Long Fibre ikomezwa na Thermoplastique (LFT), MT ikomeza kaseti mbere yatewe inda hamwe na materi yikirahure ikomeza Thermoplastique (CMT).
Ukurikije ikoreshwa ryibisabwa bitandukanye, matrike ya resin ifite PPE.PAPRT, PELPCPES, PEEKPI, PA nibindi bikoresho bya plastiki yubuhanga.
Matrike ya Thermoplastique
Matrike ya Thermoplastique ni ubwoko bwibikoresho bya termoplastique bifite imiterere yubukanishi hamwe nubushyuhe bwo guhangana nubushyuhe bushobora gukoreshwa mubicuruzwa byinshi byinganda. Matrike ya Thermoplastique ifite imbaraga nyinshi, irwanya ubushyuhe kandi irwanya ruswa.
Ubushuhe bwa thermoplastique bukoreshwa mubisabwa mu kirere ni cyane cyane ubushyuhe bwo hejuru, matrike ikora cyane, harimo PEEK, PPS na PEI, muri yo amorphous PEI ikoreshwa cyane mu kirere cyo mu kirere kuruta igice cya kirisiti ya PPS na PEEK, muri byo amorphous PEI ifite porogaramu nyinshi muburyo bwindege kuruta igice cya kirisiti ya PPS hamwe nubushyuhe bwo hejuru bwa PEEK bitewe nubushyuhe buke bwo gutunganya no kugura ibicuruzwa.
Ibisigarira bya Thermoplastique bifite imiterere myiza yubukanishi no kurwanya imiti, ubushyuhe bwo hejuru bwa serivisi, imbaraga zidasanzwe n’ubukomere, gukomera gukomeye kuvunika no kwihanganira ibyangiritse, kurwanya umunaniro mwiza, ubushobozi bwo kubumba imiterere ya geometrike n’imiterere, uburyo bwo guhinduranya ubushyuhe bw’umuriro, kongera gukoreshwa, gutuza neza ahantu habi , gusubiramo inshuro nyinshi, no gusudira, nibindi
Ibigize igizwe na resimoplastique resin hamwe nibikoresho bishimangira bifite ibyiza byinshi nko kuramba, gukomera cyane, kurwanya ingaruka nyinshi no kwihanganira ibyangiritse; fibre prepreg ntabwo ikeneye kubikwa kubushyuhe buke nanone, igihe cyo kubika kitagira imipaka; ingufi ngufi, gusudira, umusaruro mwinshi, byoroshye gusana; ibisigazwa birashobora gutunganywa no gukoreshwa; umudendezo munini wo gushushanya ibicuruzwa, birashobora gukorwa muburyo bugoye, guhuza imiterere ihindagurika, nibindi.
Gushimangira ibikoresho
Mubisanzwe, uburebure bwa fibre ngufi yongerewe imbaraga ni 0,2 kugeza kuri 0,6 mm, kandi kubera ko fibre nyinshi ziri munsi ya 70 mm z'umurambararo, bityo fibre ngufi isa cyane nifu. Fibre ngufi ishimangirwa na thermoplastique muri rusange ikorwa mukuvanga fibre mumashanyarazi yashushe. Uburebure hamwe nicyerekezo cya fibre muri matrix bituma byoroha kugera kubushuhe bwiza, kandi ibihimba bigufi bya fibre nibyo byoroshye guhimba ugereranije nibikoresho birebire kandi bikomeza fibre ishimangirwa, ariko hamwe niterambere rito mumiterere yubukanishi. Ibikoresho bigufi bya fibre bikunda kubumbwa mubice byanyuma muburyo bwo kubumba cyangwa gusohora kuko fibre ngufi ntigira ingaruka nke kumugezi.
Fibre ndende ikomezwa mubisanzwe bigera kuri mm 20 z'uburebure bwa fibre kandi mubisanzwe byateguwe ukoresheje fibre ikomeza yinjiye hamwe na resin hanyuma igacibwa kuburebure runaka. Inzira isanzwe ikoreshwa ni uburyo bwo kubumba pultrusion, aho bigenda bikomeza kugenda bivanga bya fibre hamwe na resinoplastique resin ikorwa no kurambura fibre binyuze muburyo budasanzwe bwo gupfa. Kugeza ubu, fibre ndende-yongerewe imbaraga ya PEEK ya termoplastique irashobora kugera kumiterere ya MPa zirenga 200 binyuze mumacapiro ya FDM hamwe na modulus ya GPa zirenga 20, hamwe nibikorwa byiza binyuze muburyo bwo gutera inshinge.
Fibre iri muri fibre ikomeza fibre ishimangirwa "ikomeza" kandi ifite uburebure kuva kuri metero nkeya kugeza kuri metero ibihumbi. Gukomeza fibre yibikoresho iraboneka muri rusange nka laminates, kaseti ya prereg, cyangwa udusimba, byakozwe mugutera inda ya matrike yifuzwa hamwe na fibre ikomeza.
Ni ibihe bintu biranga ibikoresho bikomatanyirijwe hamwe na fibre?
Ibikoresho bya fibre bishimangirwa nibintu byakozwe muburyo bwo guhinduranya, gushushanya cyangwa pultrusion yo gushimangira ibikoresho bya fibre, nka fibre yibirahure, fibre karubone, fibre aramide, nibindi, hamwe nibikoresho bya matrix. Ukurikije ibikoresho bitandukanye bishimangira, ibisanzwe bisanzwe byongerwaho fibre bigabanijwemo ibirahuri bya fibre byongerewe imbaraga (GFRP), karuboni fibre yongerewe imbaraga (CFRP) hamwe na fibre yongerewe imbaraga (AFRP).
Bitewe nibi bikurikira biranga fibre-fonctionnement yibigize:
(1) imbaraga nyinshi na modulus ndende;
(2) gushushanya ibintu bifatika;
(3) kurwanya ruswa neza no kuramba;
(4) coefficente yo kwagura ubushyuhe busa nubwa beto.
Ibi birangaIbikoresho bya FRPIrashobora gukenera ibyubatswe bigezweho kugeza murwego runini, muremure, umutwaro uremereye, uburemere bworoshye nimbaraga nyinshi, kandi igakora mubihe bibi, kandi ikanuzuza ibisabwa byiterambere ryubwubatsi bugezweho bwubatswe ninganda, bityo birakoreshwa cyane. mu nyubako zitandukanye za gisivili, ibiraro, umuhanda munini, inyanja, inyubako ya hydraulic hamwe nubutaka.
