2. HP-RTM txheej txheem cov yam ntxwv

HP-RTM suav nrog preform ua, resin txhaj, nias txheej txheem thiab trimming txheej txheem. Piv nrog rau cov txheej txheem RTM ib txwm muaj, cov txheej txheem HP-RTM nce cov txheej txheem tom qab txhaj tshuaj, txo qhov nyuaj ntawm kev txhaj tshuaj thiab txhaws, txhim kho cov impregnation zoo ntawm preforms, thiab shortens lub voj voog molding. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:

(1) Fast pwm filling. Cov resin tuaj yeem ua rau pwm kab noj hniav sai sai, muaj cov nyhuv infiltration zoo, txo cov npuas thiab porosity, thiab cov viscosity tsawg heev ua rau kev txhaj tshuaj ceev ntawm cov resin thiab shortens cov txheej txheem molding.

(2) High active resin. Tus resin curing cov tshuaj tiv thaiv yog nce thiab lub voj voog ntawm cov resin yog luv. Nws tau txais kev ua haujlwm siab ceev ceev-kho cov txheej txheem thiab siv cov cuab yeej ua haujlwm siab ua haujlwm siab sib xyaw thiab cov cuab yeej txhaj tshuaj kom ua tiav cov khoom sib xyaw zoo dua qub ntawm cov resin matrix. Nyob rau tib lub sijhawm, ib puag ncig kub yuav tsum tau ua thaum molding, uas zoo heev txhim kho cov tshuaj tiv thaiv kab mob ntawm cov resin, shortens lub voj voog ntau lawm, thiab stabilizes cov txheej txheem. High stability thiab repeatability,

(3) Siv tus neeg sawv cev tso tawm sab hauv thiab kev ntxuav tus kheej los txhim kho kev ua haujlwm ntawm cov khoom siv. Lub tshuab ntxuav tus kheej ntawm kev txhaj tshuaj sib tov lub taub hau yog siv, thiab ib qho kev tso tawm sab hauv yog ntxiv rau cov khoom siv raw los txhim kho kev tu kom zoo ntawm cov khoom siv. Nyob rau tib lub sijhawm, cov nyhuv ntawm cov khoom yog zoo heev, thiab cov thickness thiab cov duab sib txawv me me. Ua tiav cov nqi qis, lub voj voog luv luv (loj-ntim), kev tsim khoom zoo.

(4) Siv lub tshuab nqus tsev sai hauv pwm. Cov ntsiab lus pore nyob rau hauv qhov chaw yog txo thiab kev ua tau zoo ntawm cov khoom yog txhim kho. Nws ua tau zoo txo ​​cov pore cov ntsiab lus hauv cov khoom, txhim kho cov fiber ntau impregnation efficiency, txhim kho qhov sib txuas sib txuas muaj peev xwm ntawm fiber ntau thiab cob, thiab txhim kho cov khoom zoo.

(5) Kev sib xyaw nqus nrog cov txheej txheem molding tom qab txhaj tshuaj. Cov txheej txheem nyuaj ntawm cov khoom raug txo thiab qhov zoo ntawm cov ntaub ntawv resin-impregnated reinforced yog txhim kho. Nws txo qhov nyuaj ntawm kev tsim cov kua nplaum qhov chaw nres nkoj thiab tso qhov chaw nres nkoj ntawm RTM txheej txheem, txhim kho cov dej ntim cov peev txheej ntawm cov resin, thiab impregnation zoo ntawm fiber ntau los ntawm cov resin.

(6) Siv ob qhov chaw nruj los kaw cov pwm, thiab siv lub tshuab loj-tonnage hydraulic pressurization. Cov khoom lag luam muaj qhov sib txawv tsawg hauv cov tuab thiab cov duab peb sab. Txhawm rau kom ntseeg tau tias cov nyhuv sealing ntawm cov pwm, ob lub ntsej muag nruj yog siv los kaw cov pwm, thiab lub tshuab loj-tonnage hydraulic xovxwm yog siv rau kev nias, uas ua rau kom lub zog clamping thaum lub sij hawm molding txheej txheem thiab zoo txo ​​cov thickness thiab cov duab sib txawv. ntawm qhov chaw.

(7) Cov khoom muaj cov khoom zoo heev thiab zoo. Siv cov tshuab txau pwm thiab cov pwm ua kom zoo, cov khoom tuaj yeem tau txais qhov pom tseeb zoo hauv lub sijhawm luv luv.

(8) Nws muaj cov txheej txheem siab ruaj khov thiab rov ua dua. Kev siv qhov sib txawv ntawm kev txhaj tshuaj thiab tom qab txhaj tshuaj compression thev naus laus zis zoo heev txhim kho cov pwm ntim cov peev txheej ntawm cov resin, zoo txo ​​qhov tshwm sim ntawm cov txheej txheem tsis xws luag, thiab muaj cov txheej txheem siab rov ua dua.

3. Cov txheej txheem tseem ceeb technologies

(1) Pre-forming technology ntawm fiber reinforced cov ntaub ntawv

Fiber preforming tshuab feem ntau suav nrog: textile, knitting thiab braiding preforms; stitching preforms; tws fiber ntau txhaj tshuaj preforms; Kub nias preforms, thiab lwm yam. Ntawm lawv, kub nias shaping tshuab yog siv dav tshaj plaws. Nyob rau hauv no technology, shaping tus neeg saib xyuas yog qhov yooj yim lav, thiab fiber ntau preforming pwm thiab nias tshuab yog tus yuam sij rau fiber ntau shaping. Rau cov txheej txheem HP-RTM, cov qauv ib feem yog qhov yooj yim, yog li cov pwm shaping kuj tseem yooj yim. Qhov tseem ceeb nyob rau hauv yuav ua li cas tswj cov pwm shaping thiab pressurizing tooling kom zoo thiab orderly pressurize thiab zoo los ntawm kev tsim thiab tswj cov txheej txheem.
