Itandukaniro riri hagati ya fibre karubone nicyuma.

Mu bikoresho byinshi, ibinyabuzima bya karuboni (CFRP) byitabweho cyane kubera imbaraga zidasanzwe, gukomera kwinshi, kurwanya ruswa, no kurwanya umunaniro.

Ibintu bitandukanye biranga karuboni fibre yibikoresho nibikoresho byibyuma nabyo bitanga injeniyeri ibitekerezo bitandukanye.

Ibikurikira bizaba igereranya ryoroshye hagati ya karubone fibre hamwe nibyuma gakondo biranga itandukaniro.

1. Gukomera kwihariye n'imbaraga zihariye

Ugereranije nibikoresho byuma, ibikoresho bya fibre karubone bifite uburemere, imbaraga zidasanzwe, hamwe no gukomera.Modulus ya fibre karubone ishingiye kuri resin iruta iy'umuti wa aluminiyumu, kandi imbaraga za fibre karuboni ishingiye kuri resin irarenze cyane iy'umuti wa aluminium.

2. Kugaragara

Ibikoresho byicyuma mubisanzwe byose ni igitsina kimwe, hariho umusaruro cyangwa umusaruro uteganijwe.Kandi fibre imwe ya karubone fibre ifite icyerekezo kigaragara.

Imiterere yubukanishi ku cyerekezo cya fibre ni 1 ~ 2 byerekana ubunini burenze ubwo bujyanye na fibre vertical fibre hamwe na longitudinal na transvers shear, kandi umurongo uhangayikishije umurongo ni umurongo woroshye mbere yo kuvunika.

Kubwibyo, ibikoresho bya fibre ya karubone irashobora guhitamo inguni, igipimo cyo guteranya, hamwe nuburyo bwo gutondekanya umurongo umwe binyuze mubitekerezo bya lamination.Ukurikije ibiranga kugabana imizigo, gukomera nimbaraga zikorwa birashobora kuboneka mugushushanya, mugihe ibikoresho byuma gakondo bishobora kwiyongera gusa.

Muri icyo gihe, imbaraga zisabwa mu ndege gukomera n'imbaraga kimwe no kudasanzwe mu ndege no guhuza indege birashobora gukomera.

3. Kurwanya ruswa

Ugereranije nibikoresho byuma, ibikoresho bya fibre karubone bifite aside ikomeye kandi irwanya alkali.Fibre ya karubone ni microcrystalline imeze nka kristu ya grafite ikozwe na grafite mu bushyuhe bwo hejuru bwa 2000-3000 ° C, ifite imbaraga nyinshi zo kurwanya ruswa, muri aside hydrochlorike igera kuri 50%, aside sulfurike cyangwa aside fosifori, modulus ya elastique, imbaraga, na diameter bikomeza kuba bidahindutse.

Kubwibyo, nkibikoresho bishimangira, fibre karubone ifite garanti ihagije mukurwanya ruswa, matrix resin itandukanye mukurwanya ruswa iratandukanye.

Kimwe na karuboni isanzwe ya fibre-yongerewe imbaraga epoxy, epoxy ifite guhangana nikirere cyiza kandi iracyakomeza imbaraga zayo neza.

4. Kurwanya umunaniro

Kwiyunvikana no kurwego rwo hejuru ni ibintu byingenzi bigira ingaruka kumunaniro wa karuboni fibre yibigize.Imiterere yumunaniro isanzwe ikorerwa ibizamini byumunaniro munsi yigitutu (R = 10) hamwe numuvuduko ukabije (r = -1), mugihe ibikoresho byuma bikorerwa ibizamini byumunaniro ukabije (R = 0.1).Ugereranije n'ibice by'ibyuma, cyane cyane ibice bya aluminiyumu, ibice bya fibre karubone bifite umunaniro mwiza.Mu rwego rwa chassis yimodoka nibindi, ibinyabuzima bya karubone bifite ibyiza byo gukoresha.Mugihe kimwe, nta ngaruka nimwe igaragara muri fibre ya karubone.SN umurongo wikizamini cyateganijwe ni kimwe nikizamini kitagaragaye mubuzima bwose bwa fibre fibre laminates.

5. Gusubirana

Kugeza ubu, matrike ikuze ya karubone ikozwe muri resmosetting resin, bigoye kuvanamo no kongera gukoreshwa nyuma yo gukira no guhuza.Kubwibyo, ingorane zo kugarura fibre fibre nimwe mubibangamira iterambere ryinganda, kandi nikibazo cya tekiniki kigomba gukemurwa byihutirwa kugirango kibe kinini.Kugeza ubu, uburyo bwinshi bwo gutunganya ibicuruzwa mu gihugu no mu mahanga bifite ibiciro byinshi kandi biragoye kuba inganda.Fibre ya karubone fibre irimo gushakisha ibisubizo byongeye gukoreshwa, yarangije ingero nyinshi zumusaruro wikigereranyo, ingaruka zo gukira ni nziza, hamwe nuburyo rusange bwo gukora.

Umwanzuro

Ugereranije nibikoresho gakondo, ibikoresho bya fibre karubone bifite inyungu zidasanzwe mumiterere yubukanishi, uburemere bworoshye, gushushanya, no kurwanya umunaniro.Nyamara, umusaruro wacyo no kugarura bigoye biracyari inzitizi zo gukomeza gukoreshwa.Byizerwa ko fibre fibre izakoreshwa cyane hamwe no guhanga udushya nibikorwa.
