Iyo yekusimbisa zvinhu ndiyo inotsigira skeleton yeFRP chigadzirwa , iyo inonyanya kutarisisa iyo mechanical properties ye pultruded product. 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, kutenderera kusingachinjiki kwegirazi fiber tambo kwakadzikira mumutengo pane machira efayibha; mutengo wekunzwa wakaderera pane wejira, uye kusapindirana kwakanaka. asi simba ishoma; iyo alkali fiber yakachipa kupfuura iyo alkali-isina fiber, asi nekuwedzera kweiyo alkali content, ayo alkali resistance, corrosion resistance uye magetsi emagetsi anodzikira.
Mhando dzezvinowanzo shandiswa reinforcing materials ndeaya anotevera:
1. Girazi isina kunyorova Fiber Roving
Uchishandisa yakasimbiswa saizi mumiriri, iyo isina kuchinjika girazi fiber roving inogona kukamurwa kuita mhando nhatu: iyo plied tambo, yakananga isina kumonyoroka roving uye bulked isina kumonyoroka roving.
Nekuda kwekusagadzikana kusawirirana kwe plied tambo, zviri nyore kudonha, izvo zvinogadzira yakasununguka loop pakupera kwekudya kwemidziyo yepultrusion, iyo inokanganisa kufambira mberi kwakanaka kwekushanda.
Yakananga kurovha isina kumonyoroka ine hunhu hwekusungirira kwakanaka, kukurumidza kupinza resin, uye yakanakisa michina yezvigadzirwa, saka mazhinji acho anowanzo kushandisa akananga asina kumonereka rovings parizvino.
Bulked roving inobatsira kuvandudza simba rakachinjika rezvigadzirwa, senge crimped roving uye air-textured roving. Bulk roving ine simba repamusoro remafibhi akareba anoramba achienderera uye nekuwanda kwemafiber mapfupi. Icho chinhu chine tembiricha inopikisa, 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.
Izvo zvinodikanwa zvekushanda kwegirazi isina kuchinjika fiber roving ye pultrusion:
(1) Hapana dhiri chiitiko
(2) Uniform fiber tension
(3) Kubata zvakanaka
(4) Kuramba kwakanaka kupfeka
(5) Yakatyoka Misoro mishoma, haisi nyore kupeperetsa
(6) Kunyorova kwakanaka uye nekukurumidza resin impregnation
(7) Simba guru uye kuoma.
2. Fiberglass Mat
Kuti ugadzire zvigadzirwa zveFRP zvakanyungudutswa zvine simba rakachinjika rakakwana, zvinodikanwa kushandisa zvinhu zvekusimbisa senge akachekwa tambo mat, inoenderera tambo mat, yakasanganiswa mat, uye jira rekutenderera. Inoenderera mberi strand mat ndeimwe yeanonyanya kushandiswa girazi fiber transverse yekusimbisa zvinhu parizvino. Kuti uvandudze kutaridzika kwezvigadzirwa, mat epamusoro dzimwe nguva anoshandiswa.
Iyo inoenderera mberi tambo mat inoumbwa akati wandei akaturikidzana egirazi fibers anongoiswa zvisina tsarukano mudenderedzwa, uye mafiber anobatanidzwa neanonamira. Meti yepamusoro ipepa rakatetepa-rakafanana nematishu akaumbwa nekusarongeka 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, uye yakakwirira glue yemukati.
Zvinodiwa zve pultrusion process yegirazi fiber mat:
(1) Iine high mechanical simba
(2) Kune makemikari akasungwa akachekwa akachekwa mateti, iyo binder inofanirwa kushingirira kune kemikari uye inopisa mhedzisiro panguva yekunyura uye preforming kuti ive nechokwadi chesimba rakakwana panguva yekuumba maitiro.
(3) Kunyorova kwakanaka
(4) Ishoma fluff uye mashoma akatyoka majoini / magumo
3.PolyesterFiberSurfaceTissue
Polyester fiber surface tissue imhando itsva yekusimbisa fiber zvinhu muindasitiri yepultrusion. Kune chigadzirwa chinonzi Nexus kuUnited States, chinoshandiswa zvakanyanya muzvigadzirwa zvakanyungudutswa kutsiva girazi fiber surface mats/tissue/fleece. Iine mhedzisiro yakanaka uye yakaderera mutengo. Yakave yakabudirira kushandiswa kweanopfuura makore gumi.
Zvakanakira kushandisa polyester fiber pamusoro tishu:
(1) Inogona kuvandudza kupikisa kwemaitiro, corrosion kuramba uye kuchembera kwemhepo kwechigadzirwa
(2) Inogona kuvandudza mamiriro ekunze echigadzirwa uye kuita kuti nzvimbo yechigadzirwa ive nyore
(3) Polyester fiber pamusoro pematishu, kuita kwekunamira uye kuita kwekusimba kuri nani kupfuura C girazi repamusoro tishu / mat, uye hazvisi nyore kutyora magumo panguva ye pultrusion process, kuderedza tsaona dzekupaka.
(4) Inogona kuvandudza pultrusion kumhanya
(5) Inogona kuderedza kupfekwa kwe mold uye kugadzirisa hupenyu hwesevhisi.
4. GiraziCloth/Tape
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 kweTwo-dimensionalFmajasi& Tatu-dimensionalFmajasi
The transverse mechanical properties ye pultruded composite zvigadzirwa hazvina kunaka. Kushandiswa kwenzira mbiri-kurukwa zvinobudirira kuvandudza kusimba uye kuoma kwezvigadzirwa zvepultruded.
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 wezvigadzirwa indasitiri. Zvinoenderana nezvinodiwa zvinotakura, iyo yekusimbisa fiber inorukwa zvakananga kuita chivakwa chine matatu-dimensional chimiro, uye chimiro chakafanana nechimiro chechigadzirwa chakaumbwa icho chinoumba. Iro-nzira nhatu jira rinoshandiswa mukuita pultrusion rinogona kukunda interlaminar shear yechinyakare inosimbisa fiber pultrusion zvigadzirwa. Iyo ine zvipingamupinyi zveyakaderera shear simba uye nyore delamination, uye yayo interlayer kuita kwakaringana. (Kwakabva: Fiberglass Composites / Composites Community)
