Kushandiswa kwegirazi fiber composite machira muRTM uye vacuum infusion process

Girazi fiber composite machiraanoshandiswa zvakanyanya muRTM (Resin Transfer Molding) uye vacuum infusion maitiro, kunyanya mune zvinotevera zvinhu:

1. Kushandiswa kwegirazi fiber composite machira muRTM maitiro
RTM maitiro inzira yekuumba iyoresininobayiwa muforoma yakavharwa, uye iyo fiber preform inoiswa mukati uye inosimbiswa neresin kuyerera. Sechinhu chinosimbisa, machira egirazi fiber composite anoita basa rakakosha muRTM maitiro.

1. (1) Kusimbisa mhedzisiro: Girazi faibha inoumbwa machira anogona zvinobudirira kuvandudza michina yeRTM yakaumbwa zvikamu, senge kusimba kwesimba, kubhenda simba uye kuoma, nekuda kwesimba rawo rakakwirira uye yakakwirira modulus maitiro.
2. (2) Chinja kune yakaoma zvimiro: RTM maitiro anogona kugadzira zvikamu zvine maumbirwo akaomarara uye zvimiro. Iko kushanduka uye kugadzirwa kwegirazi fiber composite machira inogonesa kuenderana nezvinodiwa zveizvi zvakaoma zvimiro.
3. (3) Kudzora mari: Kuenzaniswa nemamwe maumbirwo ekugadzira, RTM process yakasanganiswa negirazi fiber composite machira inogona kuderedza mutengo wekugadzira uchive nechokwadi chekuita, uye yakakodzera kugadzirwa kwakakura.

2. Kushandiswa kwegirazi fiber composite jira muvacuum infusion process
Iyo vacuum infusion process (kusanganisira VARIM, nezvimwewo) inzira yekuisa nhumbu.fiber jirayekusimbisa zvinhu mune yakavharwa mold mhango pasi pevacuum yakaipa yekumanikidza mamiriro nekushandisa kuyerera uye kupinda kweresin, uye ipapo kuporesa nekuumba. Girazi fiber composite jira rinoshandiswawo zvakanyanya mukuita uku.

• (1) Impregnation mhedzisiro: Pasi pevacuum yakaipa kudzvanywa, resin inogona kunyatso kuzadza girazi refiber composite jira, kuderedza mapundu uye hurema, uye kunatsiridza kuita kwese kwezvikamu.
• (2) Shandura kuhupamhi hombe uye hombe saizi zvikamu: Iyo vacuum infusion process ine mashoma zvirambidzo pahukuru uye chimiro chechigadzirwa, uye inogona kushandiswa kuumba yakakura gobvu uye hukuru hukuru hwezvimiro zvikamu, senge mhepo turbine blades, hulls, etc. Girazi fiber composite jira, sechinhu chinosimbisa, chinogona kusangana nesimba uye kuoma zvinodiwa zvezvikamu izvi.
• (3) Kudzivirirwa kwezvakatipoteredza: Seyakavharwa mold yekuumba tekinoroji, panguva yeresininfusion uye kurapa maitiro evacuum infusion process, zvinhu zvinoputika uye zvine muchetura zvinosvibisa mhepo zvinovharirwa kune vacuum bag firimu, iro rine zvishoma kukanganisa nharaunda. Sekusvibiswa-isina kusimbisa zvinhu, girazi fiber composite jira rinowedzera kuvandudza kuchengetedzwa kwezvakatipoteredza kwemaitiro.

3. Mienzaniso chaiyo yekushandisa

• (1) Mundima yeaerospace, machira egirazi faibha akasanganiswa neRTM uye vacuum infusion process anogona kushandiswa kugadzira ndege yakatwasuka muswe, bapiro rekunze uye zvimwe zvinhu.
• (2) Muindasitiri yekuvaka ngarava, machira egirazi faibha anoumba machira anogona kushandiswa kugadzira hulls, dhizaini uye zvimwe zvimiro zvikamu.
• (3) Mumunda wesimba remhepo, machira egirazi faibha anoumbwa anoshandiswa sezvinhu zvekusimbisa uye akasanganiswa nevacuum infusion process kugadzira mashizha makuru eturbine.

Mhedziso
Girazi fiber composite machira ane yakafara application tarisiro uye yakakosha kukosha muRTM uye vacuum infusion maitiro. Nekuenderera mberi kwekufambira mberi kwetekinoroji uye kuenderera mberi kwekugadzirisa maitiro, kushandiswa kwegirazi fiber composite machira mune aya maviri maitiro achave akawedzera uye akadzika.
