Kuongorora uye kushandiswa kweFRP kupeta mhepo

Fiber winding ndiyo imwe yemaitiro ekugadzira resin matrix composite.Kune matatu makuru mafomu ekumonereka: toroidal winding, ndege inomonereka uye mhepo inotenderera.Idzi nzira nhatu dzine hunhu hwadzo, uye nzira yekunyorova yemhepo ndiyo inonyanya kushandiswa nekuda kweiyo iri nyore midziyo zvinodiwa uye mutengo wakaderera wekugadzira.

Pasi pemamiriro ekudzora kushushikana uye kufanotemerwa mutsara chimiro, iyo inoenderera faibha kana jira rakamisikidzwa neglue resin rinokuvadzwa nguva dzose, zvakaenzana uye nguva dzose pane yepakati mold kana lining nekushandisa yakakosha mhepo yemhepo, uye yobva yasimbiswa pasi peimwe tembiricha nharaunda kuti ive composite zvinhu zvekuumba nzira yezvimwe zvigadzirwa zvechimiro.Kugadzira dhizaini yefiber winding molding process:

Kune matatu maitiro makuru ekutenderera (FIG. 1-2): toroidal winding, planar winding uye spiral winding.Ridza kune yakasimbiswa zvinhu zve mold uye core axis padhuze ne90 madhigirii (kazhinji 85-89) munzira yekuenderera kumhepo pane mandrel, yakasimbiswa zvinhu zvine musimboti wematrix pamativi ese e pole hole tangent uye inoenderera. mhepo mugwara ndege pamusoro mandrel, spiral ronda akasimbisa zvinhu uye pamwe tangent kumativi ose mandrel, asi pamusoro spiral mandrel kuramba anomonereka pamusoro mandrel.

Iko kuvandudzwa kwefiber winding tekinoroji kwakabatana zvakanyanya nekuvandudzwa kwezvinhu zvekusimbisa, resin masisitimu uye zvigadzirwa zvetekinoroji.Kunyangwe muHumambo hweHan, maitiro ekugadzira matanda ezvombo akadai seGorilli nehalberd anogona kugadzirwa nekumisikidza lacquer nematanda marefu emapuranga pamwe neshenjere refu uye silika yakatenderedzwa, iyo nzira yekumoneredza faibha haina kuzove tekinoroji yekugadzira zvinhu. 1950s.Muna 1945, yekutanga-isina chitubu-isina vhiri kusimisa mudziyo yakabudirira kugadzirwa nefiber winding tekinoroji, uye muna 1947, yekutanga fiber winding muchina wakagadzirwa.Nekuvandudzwa kwemafiber akakwira senge kabhoni faibha uye aramong faibha uye kutaridzika kweiyo microcomputer inodzorwa inomonereka muchina, fiber winding process, seyakagadzirwa zvakanyanya mechanized composite yekugadzira zvinhu tekinoroji, yakagadziridzwa nekukurumidza, uye yakashandiswa mune dzinenge minda yese inogoneka. kubva kuma1960.

Nezvedu:hebeiYuniu Fiberglass Manufacturing Co., LTD.Isu tinonyanya kugadzira uye kutengesa e-mhando fiberglass zvigadzirwa, senge fiberglass roving, fiberglass yakachekwa sirika, fiberglass yakachekwa yakanzwa, fiberglass gingham, inodiwa kunzwa, fiberglass jira zvichingodaro.Kana pane zvaunoda, tapota taura nesu zvakasununguka.

Maererano nekusiyanaent chemical uye chimiro chemuviri of resin substrate panguva yekuputira, kuputira tenzira dzinogona kukamurwa kuita dzakaoma, dzakanyorova uye semi-yakaoma nzira:

1. Dry

Dry winding inotora pre-impregnated tepi padanho B mushure me pre-impregnated.Preimpregnated mitsetse inogadzirwa uye inopihwa mumiti yakakosha kana mashopu.Kumhepo yakaoma, bhandi reshinda rakagara rakanyoroveswa rinofanirwa kudziya uye kupfaviswa pamushini wekupeperesa risati rakuvadzwa kupakati mold.Hunhu hwe prepreg shinda hunogona kudzorwa nemazvo nekuti zviri mukati meglue, saizi uye mhando yetepi inogona kuwonekwa nekuongororwa isati yapetwa.Kubudirira kwekugadzira kwekuoma kwemhepo kwakakwira, kumhanya kwemhepo kunogona kusvika 100-200m / min, uye nzvimbo yekushanda yakachena.Nekudaro, yakaoma mamhepo michina yakanyanya kuoma uye inodhura, uye iyo interlaminar shear simba remagetsi zvigadzirwa yakaderera.

2. Mvura

Iyo yekunyorova inomonereka nzira ndeyekuvhuvhuta faibha pamusimboti inofa yakananga pasi pesimba rekudzora mushure mebundle uye dip glue, wobva waomesa.Midziyo yekunyorova yemhepo iri nyore, asi nekuti bhandi reshinda rinokuvadzwa pakarepo mushure mekunyudzwa, zvinonetsa kudzora uye kuongorora glue yemukati yechigadzirwa panguva yekupepeta.Zvichakadaro, kukanganisa kwakadai sebubbles uye pores zvinogadzirwa nyore nyore muchigadzirwa kana solvent mu glue solution yakasimbiswa, uye kushushikana kwakaomawo kudzora panguva yemhepo.Panguva imwecheteyo, vashandi vanoshanda mumhepo inonyungudika inonyungudika uye nharaunda yekubhururuka fiber bvudzi pfupi, mamiriro ekushanda akashata.

3. Semi-yakaoma nzira

Kuenzaniswa neyekunyorova maitiro, iyo semi-yakaomeswa maitiro inowedzera yekuomesesa midziyo munzira kubva kune faibha inonyura kuenda kune inomonereka kune yakakosha mold, uye inodzinga inonyungudutsa mune glue mhinduro yeshinda tepi.Kusiyana neiyo yakaoma maitiro, iyo semi-yakaoma nzira haivimbi neyakaoma seti ye preimpregnation michina.Kunyangwe iyo glue yemukati yechigadzirwa isiri nyore kunyatso kudzora mukuita seyakanyorova nzira uye inopfuura seti yepakati yekuomesa michina pane yakanyorova nzira, kusimba kwevashandi kwakakura, asi bubble, porosity uye kumwe kukanganisa chigadzirwa chakaderedzwa zvakanyanya.

Idzi nzira nhatu dzine hunhu hwadzo, uye nzira yekunyorova yemhepo ndiyo inonyanya kushandiswa nekuda kweiyo iri nyore midziyo zvinodiwa uye mutengo wakaderera wekugadzira.Zvakanakira nekuipira nzira nhatu dzekupeta dzinofananidzwa muTafura 1-1.
