Ikitwa tekinoroji ya 3D ikozwe muburyo bwa tekinike nuburyo butatu butarimo uburinganire bwuzuye buboneka binyuze mugutunganya fibre ndende kandi ngufi mumwanya ukurikije amategeko amwe no guhuza hamwe nundi, bikuraho ikibazo cyimikoranire kandi bitezimbere cyane kwangirika kwangirika kwibikoresho.Irashobora kubyara ubwoko bwose bwimiterere isanzwe nuburyo budasanzwe-bukomeye bwumubiri, kandi bigatuma imiterere igira imikorere-myinshi, ni ukuvuga kuboha abanyamuryango benshi.Kugeza ubu, hari inzira zirenga 20 zo kuboha ibice bitatu, ariko hariho bine bikunze gukoreshwa, aribyo kuboha inkingi;

Ibiranga inzira ya RTM
Icyerekezo cyingenzi cyiterambere cyibikorwa bya RTM nuburyo bugizwe nibice binini.VARTM, URUMURI-RTM na SCRIMP ninzira zihagarariye.Ubushakashatsi nogukoresha tekinike ya RTM birimo disipuline nikoranabuhanga byinshi, nimwe mubice byubushakashatsi bukora cyane mubigize isi.Ibyifuzo bye mubushakashatsi birimo: gutegura, imiti yimiti nuburyo bwa rheologiya ya sisitemu ya resin ifite ububobere buke kandi bukora neza;Gutegura no gutembera biranga fibre preform;Tekinoroji yo kwigana mudasobwa yuburyo bwo kubumba;Ikurikiranwa rya tekinoroji yo gushiraho inzira;Ikoreshwa rya tekinoroji yo gushushanya;Gutezimbere igikoresho gishya hamwe numukozi udasanzwe Muri vivo;Uburyo bwo gusesengura ibiciro, nibindi.
Hamwe nibikorwa byiza byayo, RTM ikoreshwa cyane mubwato, mubikoresho bya gisirikare, ubwubatsi bwigihugu, ubwikorezi, ikirere hamwe ninganda za gisivili.Ibintu nyamukuru biranga ni ibi bikurikira:
(1) Ihinduka rikomeye mubikorwa byo gukora no guhitamo ibikoresho, ukurikije umunzani utanga umusaruro,
Guhindura ibikoresho nabyo biroroshye cyane, umusaruro wibicuruzwa hagati ya 1000 ~ 20000 / umwaka.
(2) Irashobora gukora ibice bigoye bifite ubuziranenge bwubuso bwiza kandi buringaniye, kandi bifite ibyiza bigaragara mugukora ibice binini.
(3) Biroroshye kumenya imbaraga zaho hamwe na sandwich;Guhindura byoroshye ibyiciro byibikoresho byubaka
Ubwoko nuburyo byateganijwe kugirango byuzuze ibisabwa bitandukanye kuva mubikorwa bya gisivili kugeza mu kirere.
(4) Ibirimo bya fibre bigera kuri 60%.

.Irasaba resin kugira ubukonje buke, reaction nyinshi, gukiza ubushyuhe buringaniye, agaciro ka exothermic peak agaciro ko gukira, ibishishwa bito muburyo bwo kumeneka, kandi birashobora kuza vuba nyuma yo guterwa inshinge.

(8) Ubwinshi bwibicuruzwa ni buke.Ugereranije nuburyo bwo kubumba mbere, inzira ya RTM ntisaba kwitegura, gutwara, kubika no gukonjesha prereg, nta buryo bworoshye bwo guteranya intoki hamwe no gukanda imifuka ya vacuum, kandi nta gihe cyo kuvura ubushyuhe, bityo rero ibikorwa biroroshye.
Nyamara, inzira ya RTM irashobora kugira ingaruka zikomeye kumiterere yibicuruzwa byanyuma kuko resin na fibre bishobora gukorwa muburyo bwo gutera akabariro mugihe cyo kubumba, kandi fibre itembera mu cyuho, uburyo bwo gutera akabariro hamwe no gukiza ibisigazwa bishobora kugira ingaruka zikomeye kuri imitungo yibicuruzwa byanyuma, bityo bikongerera umurego no kutagenzura inzira.
