Ubudahangarwa bw'inkurikizi ni intambwe ikomeye itangwa n'ifu ya wollastonite muri resine za epoxy. Imiterere y'inyongeramusaruro ikora nk'ikintu gihagarika imyanda: iyo epoxy ihuye n'inkurikizi cyangwa stress, uduce tumeze nk'urushinge twohereza kandi tugakurura ingufu, bikarinda ko imyanda ikwirakwira. Ibi bihindura epoxy ishaje ikayihindura ibikoresho bikomeye kandi biramba, bigatuma ikoreshwa nk'imitako mu bwubatsi (sima ifatanya cyangwa icyuma) n'imyambaro irinda ku mashini, aho kudahangana n'amata, kugongana, cyangwa kunyeganyega ari ngombwa. Ikizamini kigaragaza ko kongeramo 15-25% by'ifu ya wollastonite bishobora kongera imbaraga za epoxy ku kigero cya 40-60% ugereranije na resine itaragera.

Gufata ku byuma ni ikindi kintu cy'ingenzi gikongerwamo ifu ya wollastonite. Ubuso bwayo bufite imyenge n'ubuso burebure bitera imikoranire ya mashini hamwe na epoxy matrix na substrate (nk'icyuma, ibiti, cyangwa sima), bigatuma habaho isano ikomeye. Ibi ni ingirakamaro cyane cyane mu bikoresho by'inganda bikoreshwa mu gufatanya ibikoresho bitandukanye, aho gufatana nabi bishobora gutuma ingingo zinanirwa. Mu gupfuka, gufatana neza birinda gushishwa no gutandukana, ndetse no mu bidukikije bikonje cyangwa byangiritse, bigatuma ubuzima bw'ahantu harinzwe burushaho kuba bwiza.

Gucukura gucukura ni ikibazo gikunze kugaragara muri resins za epoxy, bigatera kudahinduka kw'ibipimo, stress y'imbere, no kugabanuka kw'imbaraga z'imigozi. Ifu ya Wollastonite igabanya gucukura kugeza kuri 30% mu gihe cyo gucukura, kuko uduce twayo dukomeye tugabanya gucukura kwa epoxy matrix. Ibi ni ingenzi ku bikorwa bisaba kugenzura neza ibipimo, nko gucukura hakoreshejwe ikoranabuhanga cyangwa gukora ibumba, aho gucukura bishobora kugoreka ibice cyangwa bigatuma habaho icyuho. Gucukura gucukura bigabanya kandi ibyago byo gucika mu bipfundikizo bikomeye cyangwa imigozi minini, bigatuma habaho imikorere irambye.

Ubudahangarwa bw'imiti burushaho kwiyongera mu byuma bivanze na wollastonite bikongerwamo imbaraga. Uburyo iyi nyongeramusaruro idashobora gukora (irwanya aside, alkali, n'ibintu bishongesha) hamwe n'ubushobozi bwayo bwo gukora epoxy matrix ikomeye bigabanya kwinjira mu bintu byangiza. Ibi bituma ibyo bintu bivanze biba byiza gukoreshwa mu nganda zitunganya imiti, mu nganda zitunganya amazi yanduye, no mu bidukikije byo mu nyanja, aho kwibasirwa n'imiti ikaze cyangwa amazi y'umunyu bishobora kwangiza epoxy idakomejwe.

Ibyiza byo gutunganya ifu ya wollastonite bituma ifu yayo yoroshye kuyishyira mu buryo bwa epoxy. Kuba ifite amavuta make bituma irushaho gukurura nta bushyuhe bwinshi bwiyongere, bigatuma epoxy ikomeza kuba yoroshye kuyivanga, kuyishyiramo no kuyikwirakwiza. Ibara ry'umweru ry'ifu ntirigira ingaruka ku ibara rya epoxy, bigatuma ihinduka ry'amabara hifashishijwe amarangi. Ku bice bibiri bya epoxy, wollastonite ntibangamira uburyo ihinduka, ikanatanga igihe gihamye cyo kuyishyiraho no kuyihuza neza.

Ingano y'uduce duto n'uburyo bwo gutunganya ubuso byemerera guhindura uburyo bwo gukoresha epoxy runaka. Ingano nto (miliyone 5-10) zikoreshwa mu gusiga imyenda mito n'imitako aho bisaba kurangiza neza, mu gihe ingano nto (miliyone 20-40) zitanga imbaraga nyinshi mu miterere y'imiterere. Wollastonite yatunganyijwe ku buso (ifite silane coupling agents) irushaho guhuza na epoxy resins, yongera ikwirakwira no guhuza ku buryo bworoshye kugira ngo ikore neza.

Gukoresha neza ikiguzi bituma ifu ya wollastonite ikoreshwa mu bikoresho bya epoxy. Ugereranyije na fibre y'ikirahure cyangwa fibre ya karuboni, wollastonite itanga kuzigama amafaranga menshi mu gihe itanga uburyo bwo kunoza imikorere. Ubushobozi bwayo bwo gutwara ibintu bwinshi bugabanya ingano ya epoxy resin ihenze ikenewe, bigabanura ikiguzi rusange cyo kuyitunganya nta kwangiza imikorere.

Muri make, ubushobozi bw'ifu ya wollastonite bwo kunoza ubudahangarwa bw'inkurikizi, kongera gufatana, kugabanya gucika kw'ingufu, no kongera ubudahangarwa bw'ibinyabutabire bituma iba inyongeramusaruro nziza yo kongera imbaraga mu bikoresho bya epoxy resin. Uburyo bworoshye bwo kuyitunganya no kuyikoresha neza bushyigikira ikoreshwa ryayo mu bikoresho byo mu nganda, aho kuramba no gukora neza ari ingenzi kugira ngo igire icyo igeraho mu gihe kirekire.
