Raws li lub cev pob txha ntawm lub tsheb kauj vab, tus ncej txiav txim siab cov duab thiab kev ua haujlwm ntawm lub tsheb kauj vab mus rau qhov loj. Piv nrog rau cov hlau lossis txhuas alloy thiab lwm yam khoom siv tam sim no siv hauv kev tsim tsheb kauj vab, cov yam ntxwv tseem ceeb ntawm lub tsheb kauj vab siv cov ntaub ntawv carbon fiber ntau yog raws li hauv qab no: Lub sijhawm yog dab tsi:
1. Lub zog muaj zog, lub teeb yuag
Txhua tus paub tias qhov ntom ntawm cov ntaub ntawv carbon fiber ntau tsawg heev. Nyob ntawm cov ntaub ntawv uas nws muaj, nws yog feem ntau ntawm 1.5-1.8g/cm3. Tam sim no, lub zog siab tshaj plaws ntawm cov pa roj carbon fiber ntau tuaj yeem siab txog 7000Mpa, yog li lub zog tensile ntawm carbon fiber ntau dua li cov hlau. Ntau ntau.
2. Zuag qhia tag nrho molding
Cov txheej txheem molding yooj yim rau lub tsheb kauj vab thav duab ua los ntawm cov ntaub ntawv carbon fiber ntau yog cov txheej txheem hloov pauv hloov pwm, lossis RTM. Cov txheej txheem yog txheej txheem molding nrov hauv xyoo 1990s. Cov nplooj ntawv fiber ntau tau muab tso rau ntawm cov pwm thiab tom qab ntawd ntws mus rau hauv cov resin thiab hlawv, yog li tsis tas yuav xav txog kev sib txuas ntawm cov thav ntawv.
Qhov kom zoo dua ntawm kev siv cov txheej txheem RTM yog cov txheej txheem yooj yim, qhov nruab nrab txuas ntawm prepreg raug zam, thiab cov txheej txheem qis qis qis yog siv los txuag cov nqi khoom siv ntxiv. Kaw pwm ua haujlwm, huv si ua haujlwm. Pwm kev khiav hauj lwm ib puag ncig yog kaw thiab huv si, yooj yim kom paub automation, thiab qhov zoo ntawm lub workpiece yog zoo.
3. Kev cuam tshuam zoo
Lub elasticity tus nqi yog ib qho tseem ceeb qhia ntawm kev ua si tsheb kauj vab ncej. Vim cov ntaub ntawv uas muaj siab elastic modulus muaj kuj siab hardness, lawv yuav deform tsawg dua tom qab loaded. Rau qee cov ntaub ntawv uas tsis tshua muaj elastic modulus, lawv yog mos, yog li thaum lawv dais ib tug loj load, lub deformation yuav kuj loj. Raws li cov khoom siv tsheb kauj vab, qee qhov yuav tsum tau deform ntau dua, thiab qee qhov yuav tsum tau deformation tsawg dua. Piv txwv li, hluav taws xob tsheb thiab maus taus muaj kev poob siab absorbers.
