Urubaho rwiza rw'igare rugomba kuba rwujuje ibintu bitatu: uburemere bworoheje, imbaraga zihagije no gukomera cyane. Nk'umukino w'igare, urubaho ni rwo buremere
Uko imodoka yoroheje niko irushaho kuba nziza, niko imbaraga zigabanuka kandi niko ushobora kuyitwara vuba:
Ingufu zihagije bivuze ko urufatiro rutazacika cyangwa ngo rugororoke munsi y'umuhanda ukomeye;
Uburimbane bwinshi busobanura uburimbane bw'umukingo. Hari igihe umukingo udafite uburimbane buke ushobora kutagira impungenge z'umutekano, ariko imbaraga z'umukingo zikwirakwira iyo ugenda.
Itandukaniro ry'umuyobozi rituma umugenzi yumva nk'aho igare ririmo gukurura iyo arikandagiyeho. Nubwo urwego rw'igare rwaba rworoheje kandi rukomeye bihagije, ariko gukomera kwarwo kukaba ari guke, ni kimwe.
Igare rya siporo ridafite ireme. Mu bwoko bw'imodoka ziri ku isoko, ibikoresho bya fremu bishobora kuzuza amahame meza yavuzwe haruguru ni: aloyi ya aluminiyumu,
Hari ubwoko bune bwa fibre ya karuboni, aloyine ya titaniyumu n'icyuma cya aloyi.

1. Ibikoresho by'icyuma bya Alloy:
Icyuma ni cyo gikoresho gakondo cyane ku magare. Ibyuma bitandukanye bigezweho bishobora gukoreshwa mu gukomera, guhindagurika, gutwara ibintu no guhagarara neza.
Ibisubizo byiza biraboneka. Ikibazo cyonyine ni uko uburemere bwa t bw'icyuma ari inenge, kandi uburemere buruta umubare wa t w'ibikoresho. -Muri rusange, icyuma cy'ibyuma
Igiciro cy'ibikoresho kirahendutse. Ariko, igiciro cyiza cy'icyuma gikozwe mu byuma n'icyuma cya molybdenum ntabwo gihendutse.
Ibikoresho bishobora kugereranywa.

2. Ingano ya aluminiyumu:
Uburyo aluminiyumu ikoresha butuma umuntu yumva ibintu neza, yoroheje, yoroheje, kandi ikomeye cyane, ariko nanone igaragaza uburyo buri gace ka J gahuzwa n’ibintu biri hasi.
Ihumure riragabanuka gato. Rihendutse kandi hari ubwoko bwinshi bw'amashusho, ni ubwoko bukwiye kugurwa na buri wese.

3. Fibre ya karuboni:
Ibiranga fibre ya karuboni: uburimbane, kumva ko igendera mu muhanda uhamye, gukomeza urugendo rw'urugendo rurerure, no kumererwa neza cyane. Ingorane ni uko igiciro kiri hejuru cyane, kandi
Igihe mpuzandengo cy'ubuzima bw'imashini (yabazwe uhereye ku ruganda) ni imyaka 5 cyangwa 6 gusa. Nubwo nta kintu kigaragara mu gitereko mu myaka 6, formula yayo y'ibinyabutabire iracyari
E yangiritse, kandi ntibyemewe ko abagendera ku mafarashi bakomeza kuyikoresha.

4. Ingano ya Titanium:
Imiterere ya aloyi ya titaniyumu isa cyane n'uruvange rwa aloyi ya aluminiyumu na fibre ya karuboni. Ishobora kugira uburimbane nk'ubwa fibre ya karuboni kandi ishobora no kwishimira aloyi ya aluminiyumu.
Ubworoshye n'ubudahangarwa bwayo. Icyihariye cyayo giterwa n'uko coefficient yo kwaguka ihinduka, bigatuma bidashoboka gusiga irangi ku buso bw'icyuma, ariko ku bw'amahirwe ni uko irangi rya titaniyumu
Ntabwo byoroshye kwangiza no gukaraba, kandi ibara naryo ni umwihariko. Ariko igiciro cyaryo nacyo ntikigereranywa n'ibindi bitatu bya mbere.
