Iyo yekusimbisa zvinhu ndiyo inotsigira skeleton yechigadzirwa cheFRP, icho chinotarisisa ma mechanika echigadzirwa chakaputirwa. Iko kushandiswa kwezvinhu zvekusimbisa zvakare kune imwe mhedzisiro yekudzikisa shrinkage yechigadzirwa uye kuwedzera iyo thermal deformation tembiricha uye yakaderera tembiricha kukanganisa simba.
Mukugadzirwa kwezvigadzirwa zveFRP, kusarudzwa kwezvinhu zvekusimbisa kunofanirwa kutarisisa zvizere kuumbwa kwechigadzirwa, nekuti mhando, nzira yekuisa uye zvirimo zvekusimbisa zvinhu zvine pesvedzero huru pakuita kweFRP zvigadzirwa, uye ivo vanonyanya kuona iyo mechanic. simba uye elastic modulus yeFRP zvigadzirwa. Kuita kwezvigadzirwa zve pultruded kushandisa zvakasiyana-siyana zvekusimbisa zvinhu zvakasiyana zvakare.
Pamusoro pezvo, paunenge uchisangana nezvinodiwa zvechigadzirwa chemaitiro ekuumba, mutengo unofanirwa kutariswa, uye zvakachipa zvekusimbisa zvinhu zvinofanirwa kusarudzwa zvakanyanya sezvinobvira. Kazhinji, iyo isiri-yekunhonga roving yegirazi fiber tambo yakaderera mumutengo pane machira efayibha; mutengo wegirazi fiber matsyakaderera pane iyo yemucheka, uye kusapinda kwayo kwakanaka. , asi simba racho ishoma; iyo alkali faibha yakachipa kupfuura iyo alkali-isina fiber, asi nekuwedzera kweiyo alkali content, ayo alkali resistance, corrosion resistance, uye magetsi emagetsi anodzikira.
Mhando dzezvinowanzoshandiswa zvekusimbisa zvinhu ndezvinotevera
1. Girazi isina kunyorova fiber roving
Kushandisa yakasimbiswa saizi agent, isina kumonyorokagirazi fiber rovinginogona kupatsanurwa mumhando nhatu: plied sirika mbishi, yakananga isina kumonyoroka roving uye bulked untwisted roving.
Nekuda kwekukakavadzana kusina kuenzana kwe plied tambo, zviri nyore kudonha, izvo zvinogadzira yakasununguka loop pakupera kwemafuro emidziyo yepultrusion, iyo inokanganisa kufambira mberi kwakanaka kwekushanda.
Direct untwisted roving ine hunhu hwekuunganidzira kwakanaka, kukurumidza kupinza resin, uye yakanakisa mechaniki zvivakwa zvezvigadzirwa, saka mazhinji akananga asina kumonyoroka rovings anowanzo shandiswa parizvino.
Bulked rovings inobatsira kuvandudza simba rakachinjika rezvigadzirwa, senge crimped rovings uye air-textured rovings. Bulk roving ine simba repamusoro remafibhi akareba anoramba achienderera uye nekuwanda kwemafiber mapfupi. Icho chinhu chine high-temperature resistance, yakaderera thermal conductivity, corrosion resistance, high capacity uye high filtration performance. Mamwe mafiber akaiswa mumonofilament state, saka anogona zvakare kuvandudza pamusoro pemhando yezvigadzirwa zvepultruded. Parizvino, machira akakura ave kushandiswa zvakanyanya kumba nekune dzimwe nyika, seshinda dzakarukwa uye dzemachira ekushongedza kana machira akarukwa. Inogona kushandiswa kugadzira friction, insulation, kudzivirira kana kuisa chisimbiso zvinhu.
Kuita zvinodiwa kune isina kuchinjika girazi fiber rovings ye pultrusion:
(1) Hapana chiitiko chakanyanyisa;
(2) Iyo fiber tension yakafanana;
(3) Kubata zvakanaka;
(4) Kuramba kwakanaka kupfeka;
(5) Misoro mishoma yakatyoka, uye haisi nyore kupeperetsa;
(6) Kunyorova kwakanaka uye nekukurumidza resin impregnation;
(7) Simba guru uye kuoma.
2. Girazi fiber mat
Kuti ugadzire zvigadzirwa zveFRP zvakakwenenzverwa zvine simba rakachinjika rakakwana, zvinhu zvekusimbisa senge akachekwa tambo mat, inoenderera tambo mat, yakasanganiswa mat, uye isina kumonereka jira rinofanira kushandiswa. Inoenderera mberi strand mat ndeimwe yeanonyanya kushandiswa girazi fiber transverse yekusimbisa zvinhu parizvino. Kuti uvandudze kutaridzika kwezvigadzirwa,surface matdzimwe nguva inoshandiswa.
Iyo inoenderera mberi tambo mat inoumbwa akati wandei akaturikidzana egirazi fibers anongoiswa zvisina tsarukano mudenderedzwa, uye mafiibhi anosungirirwa nemanamira. Iyo yepamusoro inonzwa ipepa rakatetepa-rakanzwika rakagadzirwa nekusarudzika uye zvakafanana kuisa tambo dzakachekwa dzehurefu hwakatarwa uye dzakabatanidzwa neinamira. Iyo fiber yemukati ndeye 5% kusvika 15%, uye ukobvu ndeye 0.3 kusvika 0.4 mm. Inogona kuita kuti pamusoro pechigadzirwa chive chakatsetseka uye chakanaka, uye kuvandudza kuchembera kwechigadzirwa.
Hunhu hwegirazi fiber mat ndeiyi: kuvharika kwakanaka, nyore kugadzika neresin, yakakwira glue yemukati
Zvinodiwa zve pultrusion process yegirazi fiber mat:
(1) Iine simba remagetsi rakakwirira
(2) Pamakemikari akasungwa akachekwa tambo mats, iyo binder inofanirwa kushingirira kumakemikari uye zvinopisa zvinokonzeresa panguva yekunyura uye preforming kuti ive nechokwadi chakakwana simba panguva yekuumba maitiro;
(3) Kunyorova kwakanaka;
(4) Ishoma furu uye misoro mishoma yakatyoka.
Fiberglass Stitched mat
Girazi fiber composite mat
3. Polyester fiber surface mat
Polyester fiber pamusoro inonzwa imhando nyowani yekusimbisa fiber zvinhu muindasitiri yepultrusion. Kune chigadzirwa chinonzi Nexus muUnited States, iyo inoshandiswa zvakanyanya muzvigadzirwa zvepultruded kutsivagirazi fiber pamusoro pemateti. Iine mhedzisiro yakanaka uye yakaderera mutengo. Yakave yakabudirira kushandiswa kweanopfuura makore gumi.
Zvakanakira kushandisa polyester fiber tissue mat:
(1) Inogona kuvandudza kupikisa kwemaitiro, kusagadzikana kwekuora uye kuchembera kwemhepo yezvigadzirwa;
(2) Inogona kuvandudza chimiro chepamusoro chechigadzirwa uye kuita kuti pamusoro pechigadzirwa ive nyore;
(3) Iko kushandiswa uye kusimba kweiyo polyester fiber pamusoro inonzwa iri nani kupfuura C girazi pamusoro yakanzwa, uye hazvisi nyore kutyora magumo panguva ye pultrusion process, kuderedza njodzi dzekupaka;
(4) The pultrusion speed inogona kuwedzerwa;
(5) Inogona kuderedza kupfekwa kwefodya uye kuvandudza hupenyu hwebasa remuumbi
4. Girazi fiber jira tepi
Mune zvimwe zvakakosha zvigadzirwa zve pultruded, kuitira kuti isangane nezvimwe zvakakosha kuita zvinodiwa, jira regirazi rine hupamhi yakatarwa uye ukobvu husingasviki 0.2mm rinoshandiswa, uye simba raro rekusimba uye kuchinjika simba rakanaka kwazvo.
5. Kushandiswa kwemachira maviri-dimensional uye matatu-dimensional machira
Iyo inochinjika mechanicha zvimiro zvezvakadhonzwa zvinoumbwa zvigadzirwa hazvina kunaka, uye kushandiswa kwebidirectional braiding zvinobudirira kunatsiridza kusimba uye kuomarara kwezvakagadzirwa zvigadzirwa.
Idzi shinda neshinda dzemucheka wakarukwa uyu hadzina kupindirana, asi dzakarukwa neimwe midziyo yakarukwa, saka zvakasiyana zvachose nejira regirazi rechinyakare. Mafibisi ari mugwara rega rega ari mucollimated state uye haaite Chero kukotama, uye nokudaro kusimba uye kuomarara kwechigadzirwa chakanyungudutswa, chakakwira zvakanyanya kupfuura icho chemusanganiswa wakagadzirwa nekuramba uchinzwa.
Parizvino, nzira nhatu dzekuruka tekinoroji yave inonyanya kutaridzika uye inoshanda tekinoroji kusimudzira munda mumubatanidzwa wezvinhu indasitiri. Zvinoenderana nezvinodiwa zvemutoro, iyo yekusimbisa fiber inorukwa zvakananga kuita chivakwa chine matatu-dimensional chimiro, uye chimiro chakafanana neicho chechigadzirwa chakaumbwa icho chinoumba. Iro-nzira nhatu jira rinoshandiswa mukuita pultrusion kukurira interlaminar shear yechinyakare inosimbisa fiber pultrusion zvigadzirwa. Iyo ine zvipingamupinyi zveyakaderera shear simba uye nyore delamination, uye yayo interlayer kuita kwakaringana.
