Muri iki gihe cyiterambere ryihuse ryikoranabuhanga, karubone fibre ikora izina ryayo mubice byinshi bitewe nibikorwa byabo byiza. Kuva murwego rwohejuru rushyirwa mubikorwa byogajuru kugeza kumunsi ukenera ibicuruzwa bya siporo, ibinyabuzima bya karubone byagaragaje imbaraga nyinshi. Ariko, kugirango utegure imikorere ya karubone fibre ikora cyane, kuvura ibikorwa byafibre fibreni intambwe y'ingenzi.
Carbone fibre hejuru ya electron microscope ishusho
Fibre fibre, ibikoresho bya fibre ikora cyane, ifite ibintu byinshi bikomeye. Igizwe ahanini na karubone kandi ifite imiterere ndende. Uhereye kubireba imiterere yubuso, ubuso bwa fibre karubone iroroshye kandi ifite amatsinda make akora. Ibi biterwa nuko mugihe cyo gutegura fibre karubone, carbone yubushyuhe bwo hejuru hamwe nubundi buryo bwo kuvura bituma ubuso bwa fibre karubone bugaragaza imiterere idahwitse. Uyu mutungo wubuso uzana urukurikirane rwibibazo byo gutegura karubone fibre.
Ubuso bworoshye butuma isano iri hagati ya fibre karubone nibikoresho bya matrix bidakomeye. Mugutegura ibihimbano, biragoye kubintu bya matrix gukora umurunga ukomeye hejuru yfibre, bigira ingaruka kumikorere rusange yibikoresho. Icya kabiri, kubura amatsinda akora bigabanya imiterere yimiti hagati ya fibre karubone nibikoresho bya matrix. Ibi bituma guhuza imiyoboro hagati yibi byombi bishingiye cyane cyane ku ngaruka zifatika, nko gushiramo imashini, nibindi, akenshi bidahagaze neza bihagije kandi bikunda gutandukana iyo bikorewe imbaraga ziva hanze.
Igishushanyo mbonera cya interlayer gushimangira imyenda ya karubone na karubone nanotubes
Kugirango ukemure ibyo bibazo, kuvura ibikorwa bya fibre ya karubone biba ngombwa. Bikorafibre fibreErekana impinduka zikomeye mubice byinshi.
Kuvura ibikorwa byongera ubuso bwa fibre fibre. Binyuze mu okiside ya chimique, kuvura plasma nubundi buryo, ibinogo bito na shobora birashobora gushirwa hejuru ya fibre karubone, bigatuma ubuso butagaragara. Ubuso bubi bwongera umwanya uhuza fibre ya karubone nibikoresho bya substrate, biteza imbere imashini ihuza byombi. Iyo ibikoresho bya matrix bihujwe na fibre ya karubone, nibyiza cyane kwishira muri izo nyubako zikaze, bigakora umurunga ukomeye.
Uburyo bwo kuvura bushobora kumenyekanisha amatsinda menshi akora neza hejuru ya fibre karubone. Aya matsinda akora arashobora kwitwara neza hamwe nitsinda ryimikorere ijyanye nibikoresho bya matrix kugirango bibe bihuza imiti. Kurugero, kuvura okiside irashobora gutangiza amatsinda ya hydroxyl, amatsinda ya carboxyl nandi matsinda akora hejuru ya fibre karubone, ishobora kubyitwaramo hamwe naepoxyamatsinda muri resin matrix nibindi kugirango bibe covalent bonds. Imbaraga ziyi miti ihuza cyane iruta iyo guhuza umubiri, bitezimbere cyane imbaraga zo guhuza imiyoboro hagati ya fibre karubone nibikoresho bya matrix.
Ingufu zo hejuru za fibre ikora ya karubone nayo yiyongera cyane. Ubwiyongere bw'ingufu zo hejuru byorohereza fibre ya karubone guhanagurwa nibikoresho bya matrix, bityo bikorohereza ikwirakwizwa no kwinjira mubintu bya matrix hejuru ya fibre karubone. Muburyo bwo gutegura ibihimbano, ibikoresho bya matrix birashobora gukwirakwizwa cyane hafi ya fibre ya karubone kugirango habeho imiterere yuzuye. Ibi ntabwo bitezimbere gusa imiterere yubukorikori bwibikoresho, ahubwo binatezimbere indi miterere yabyo, nko kurwanya ruswa no guhagarara neza.
Fibre ikora ya karubone ifite ibyiza byinshi byo gutegura fibre fibre.
Kubireba imiterere yubukanishi, imbaraga zo guhuza imbaraga hagati yimikorerefibre fibrenibikoresho bya matrix byatejwe imbere cyane, bifasha ibihimbano kwimura neza stress iyo ikorewe imbaraga ziva hanze. Ibi bivuze ko imiterere yubukorikori bwimbaraga nkimbaraga na modulus byateye imbere cyane. Kurugero, mukibuga cyindege, gisaba ibintu byubukorikori buhanitse cyane, ibice byindege bikozwe hamwe na fibre ikora ya karubone ikora birashobora kwihanganira imitwaro myinshi yindege kandi bikazamura umutekano nubwizerwe bwindege. Mu rwego rwibicuruzwa bya siporo, nk'amagare yamagare, clubs za golf, nibindi, gukora karubone fibre ikora irashobora gutanga imbaraga no gukomera, mugihe kugabanya ibiro no kuzamura uburambe bwabakinnyi.
Kubyerekeranye no kurwanya ruswa, bitewe no kwinjiza amatsinda akora neza hejuru ya fibre ikora ya karubone ikora, ayo matsinda akora arashobora gushiraho imiti ihamye ihujwe nibikoresho bya matrix, bityo bikazamura ruswa yo kurwanya ruswa. Mubihe bimwe bidukikije bidukikije, nkibidukikije byo mu nyanja, inganda z’imiti, nibindi, byakozwekaruboni fibre ikorairashobora kurwanya neza isuri yibitangazamakuru byangirika kandi ikongerera igihe cya serivisi. Ibi bifite akamaro kanini kubikoresho bimwe na bimwe bikoreshwa mubidukikije bikaze igihe kirekire.
Kubijyanye nubushyuhe bwumuriro, guhuza imiyoboro myiza hagati ya fibre karubone ikora nibikoresho bya matrix birashobora kuzamura ubushyuhe bwumuriro wibintu. Munsi yubushyuhe bwo hejuru, ibiyigize birashobora kugumana imiterere yubukanishi no guhagarara neza, kandi ntibikunze guhinduka no kwangirika. Ibi bituma karubone fibre ikora ifite ibyifuzo byinshi mubisabwa mubushyuhe bwo hejuru, nkibice bya moteri yimodoka hamwe na moteri yindege ibice bishyushye.
Kubijyanye no gutunganya imikorere, fibre ikora ya karubone yongereye ibikorwa byubuso no guhuza neza nibikoresho bya matrix. Ibi byorohereza ibikoresho bya matrix kwinjira no gukira hejuru ya fibre ya karubone mugihe cyo gutegura ibikoresho, bityo bikazamura imikorere no gutunganya ibicuruzwa. Muri icyo gihe, ibishushanyo mbonera bya karubone fibre ikora nabyo byongerewe imbaraga, bikabemerera guhindurwa mubikorwa bitandukanye no kuzuza ibisabwa bitandukanye byubuhanga.
Kubwibyo, kuvura ibikorwa byofibre fibreni urufunguzo rwibanze mugutegura imikorere ya karubone fibre ikora. Binyuze mu kuvura ibikorwa, imiterere yubuso bwa fibre karubone irashobora kunozwa kugirango yongere ububobere bwubuso, itangire amatsinda akora, kandi itezimbere ingufu zubutaka, kugirango tunoze imbaraga zihuza imiyoboro hagati ya fibre karubone nibikoresho bya matrix, hanyuma ushireho urufatiro kugirango hategurwe fibre fibre yibikoresho bifite imashini nziza, irwanya ruswa, ituze ryumuriro nibikorwa byo gutunganya. Hamwe niterambere ryiterambere rya siyanse nikoranabuhanga, byizerwa ko tekinoroji ya fibre fibre ikora izakomeza guhanga udushya no gutera imbere, itanga inkunga ikomeye mugukoresha kwinshi kwa fibre fibre.
