Pultrusioncomposite zvinhundeyepamusoro-inoshanda fiber-reinforced polymer (FRP) macomposites anogadzirwa achishandisa nzira inoenderera inozivikanwa sepultrusion.

Mukuita uku, mafibers anoenderera mberi (akaita segirazi kana kabhoni) anodhonzwa kuburikidza nekugeza kwe thermosetting resin (senge epoxy resin, polyester, kana vinyl ester), uyezve molds inoshandiswa kugadzira zvinhu sezvaunoda. Resin yacho inobva yapora, ichiita chinhu chakasimba, chakareruka, uye chinogara chakaumbwa.

PultrusionResins 

Iyo matrix resin chinhu chakakosha chepultrusion composite zvinhu. Common Pultrusion resin anosanganisira epoxy, polyurethane, phenolic, vinyl ester, uye ichangoburwa yakadzidzwa zvakanyanya thermoplastic resin masisitimu. Nekuda kwehunhu hwe pultrusion composite zvinhu, iyo matrix resin inoda kuve yakaderera viscosity, kukurumidza kuita mazinga pakupisa kwakanyanya. Pakusarudza iyo matrix resin, zvinhu zvakaita se pultrusion reaction rate uye resin viscosity zvinoda kutariswa. Yakakwira viscosity inogona kukanganisa iyo lubrication maitiro panguva yekugadzira chigadzirwa.

Epoxy Resin 

Pultrusion composite zvinhu zvakagadzirirwa ne epoxy pultrusion resins inoratidza simba rakakura uye inogona kushandiswa pasi pemamiriro ekupisa kwepamusoro, nekukurumidza kurapwa.

speed. Nekudaro, zvinonetsa senge brittleness yezvinhu, nguva pfupi yekushandisa, kushomeka kwekupinda, uye yakanyanya kurapa tembiricha inodzikamisa kusimudzira kweindasitiri yemagetsi emhepo muChina, kunyanya mumhepo turbine blade uye midzi yemidziyo.

Polyurethane 

Polyurethane resin ine yakaderera viscosity, inobvumira yakakwira girazi fiber yemukati kana ichienzaniswa nepolyester kana vinyl ester resin. Izvi zvinokonzeresa pultrusion polyurethane composite zvinhu zvine kubhenda modulus ye elasticity pedyo neiyo yealuminium. Polyurethane inoratidzira yakanakisa kugadzirisa kushanda kana ichienzaniswa nemamwe marezeni.

Phenolic Resin 

Mumakore achangopfuura, pultrusion composite zvinhu zvinoshandisa phenolic resin zvakawana kutariswa nekuda kwekudzika kwazvo huturu, kuderera kwehutsi kuburitsa, kuramba kwemoto, uye vakawana zvikumbiro munzvimbo dzakadai sekutakura njanji, mapuratifomu ekuchera mafuta ekumahombekombe, mashopu anodzivirira makemikari, uye mapaipi. . Nekudaro, zvechinyakare phenolic resin kurapa maitiro anononoka, zvichikonzera kureba kuumbwa kutenderera, uye kuumbwa kwemabhuru panguva yekukurumidza kuenderera kugadzirwa, zvichikanganisa kuita kwechigadzirwa. Acid catalysis masisitimu anowanzo shandiswa kukunda matambudziko aya.

Vinyl Ester Resin 

Vinyl ester doro resin inoratidzira yakanakisa mechaniki zvivakwa, kupisa kupisa, corrosion resistance, uye nekukurumidza kurapa. Munenge mugore ra2000, yaive imwe yezvaidiwa resin yezvigadzirwa zvepultrusion.

Thermoplastic Resin 

Thermoplastic composites inokunda zvimhingamupinyi zvezvakatipoteredza zve thermosetting composite, ichipa kuchinjika kwakasimba, kupesana nemhedzisiro, kushivirira kwekukuvara kwakanaka, uye kunyorova zvinhu. Ivo vanoramba kuora kwemakemikari uye kwezvakatipoteredza, vane kukurumidza kurapa maitiro pasina kuita kwemakemikari, uye inogona kukurumidza kugadziriswa. Kazhinji thermoplastic resins inosanganisira polypropylene, naironi, polysulfide, polyether ether ketone, polyethylene, uye polyamide.

Zvichienzaniswa nezvinhu zvechinyakare zvakaita sesimbi, ceramics, uye mapurasitiki asina kusimbiswa, girazi fiber-reinforced pultrusion composites ine akawanda mabhenefiti. Ivo vane yakasarudzika tsika dhizaini kugona kusangana nezvinodiwa zvechigadzirwa.

Zvakanakira zvePultrusionComposite Materials:

1.Manufacturing Efficiency: Pultrusion molding inzira inopfuurira ine zvakanakira zvakadai sehuwandu hwekugadzirwa kwepamusoro, kuderera kwemari, uye kukurumidza nguva dzekutumira zvichienzaniswa nedzimwe nzira dzekugadzira composite.

2.High Strength-to-Weight Ratio: Pultrusion composite zvinhu zvakasimba uye zvakasimba asi zvisingaremi. Carbon fiber Pultrusions yakareruka kupfuura simbi uye zvimwe zvinhu, zvichiita kuti ive yakakodzera kune huremu-huremu maapplication muaerospace, mota, uye zvekufambisa.

3.Corrosion Resistance: FRP composites inoratidzira yakasimba corrosion resistance, zvichiita kuti zvive zvakakodzera kushandiswa mumaindasitiri akadai semakemikari ekugadzirisa, marine, petroleum, uye gasi rechisikigo.

4.Electrical Insulation: Girazi fiber pultrusions inogona kugadzirwa kuti ive isina-conductive, ichiita kuti ive sarudzo yakanaka yekushandiswa kwemagetsi inoda dielectric performance.
Dimensional Kugadzikana: Pultrusion composite zvinhu hazvikanganise kana kutsemuka nekufamba kwenguva, izvo zvakakosha kune zvikumbiro zvine kushivirira chaiko.

5.Custom Design: Zvikamu zvepultrusion zvinogona kugadzirwa mumhando dzakasiyana-siyana uye hukuru, kusanganisira matanda, machubhu, matanda, uye mamwe maitiro akaoma. Iwo anogoneka zvakanyanya, achibvumira dhizaini misiyano mumhando yefiber, vhoriyamu yefiber, resin rudzi, chifukidzo chepamusoro, uye kurapwa kuti isangane nekuita chaiko uye zvinodiwa zvekushandisa.

Zvakaipa PakushandisapultrusionComposite Materials:

1.Limited Geometric Shapes: Pultrusion composite zvinhu zvinongogumira kune zvikamu zvinogara kana zvinenge zvisingachinji-zvikamu nekuda kwekuenderera mberi kwekugadzira iyo fiber-yakasimbiswa zvinhu inodhonzwa kuburikidza ne molds.

2.High Manufacturing Costs: Iyo molds inoshandiswa mu pultrusion molding inogona kudhura. Dzinoda kugadzirwa kubva kune zvemhando yepamusoro zvinhu zvinokwanisa kumirisana nekupisa uye kudzvanywa kweiyo pultrusion process, uye dzinofanirwa kugadzirwa neakasimba machining kushivirira.

3.Low Transverse Strength: The transverse simba re pultrusion composite zvinhu zvakaderera kudarika simba re longitudinal, zvichiita kuti zvive zvisina simba mukutungamira perpendicular kune fibers. Izvi zvinogona kugadziriswa nekubatanidza akawanda-axial machira kana fiber panguva ye pultrusion process.

4.Difficult Repair: Kana Pultrusion composite zvinhu zvakakuvadzwa, kuzvigadzirisa zvinogona kuva zvakaoma. Zvose zvikamu zvingada kuchinjwa, izvo zvinogona kuva zvose zvinodhura uye zvinotora nguva.

Zvikumbiro zvePultrusionComposite Materialspultrusioncomposite zvinhu zvinowana kushandiswa kwakapararira mumaindasitiri akasiyana, kusanganisira:
