Cov kev lag luam tiv thaiv thiab aerospace ua haujlwm ntawm qhov tshiab ntawm kev tshawb fawb txog cov khoom siv, xav tau cov khoom uas tuaj yeem tiv taus cov xwm txheej hnyav - los ntawm qhov kub thiab ablation mus rau G-forces siab thiab kev raug tshuaj lom neeg. Hauv qhov chaw muaj kev pheej hmoo siab no, **phenolic molding compounds (PMCs) txhawb nqa nrog cov xov txiav** tau ua pov thawj tias yog qhov kev daws teeb meem tseem ceeb.

Tsim los rau qhov kawg

Cov phenolic resins, ib hom thermosetting polymers, yog nto moo rau lawv qhov kev ruaj khov thermal zoo heev, qhov sib xws ntawm qhov loj me, thiab kev tiv thaiv hluav taws. Thaum cov resins no raug sib xyaw nrog cov xov txiav uas raug txiav thiab ua haujlwm tau zoo (feem ntau yog iav lossis silica fiber), lawv tsim cov khoom sib xyaw ua ke uas tsim los rau cov ntawv thov uas xav tau ntau tshaj plaws.

Qhov kev suav nrog cov xov txiav rau hauv cov tshuaj molding muab kev txhawb nqa tseem ceeb, hloov pauv cov khoom siv:

* **Kev Tiv Thaiv Ablation Zoo Tshaj Plaws:** Hauv kev siv dav hlau thiab foob pob hluav taws, cov khoom sib xyaw raug rau qhov kub thiab txias heev. Cov PMCs uas muaj zog feem ntau siv rau hauv **cov nozzles foob pob hluav taws, cov ntaub thaiv cua sov, thiab cov chav hlawv** vim tias lawv tiv taus ablation (kev yaig ntawm qhov chaw los ntawm cua sov) thaum tswj kev ruaj khov ntawm cov qauv hauv qab cov xwm txheej kub.

* **Lub Zog Thiab Kev Ruaj Khov Thaum Kub Siab:** Tsis zoo li cov thermoplastics, cov thermoset phenolics tsis yaj. Cov xov txiav tau xauv cov resin kho kom ruaj khov, ua rau cov khoom siv zoo heev **tsis kam nkag** thiab **rigidity** txawm tias kub tshaj 300°C (thiab qee zaum siab dua hauv cov haujlwm ablative).

* **Kev Ua Raws Li Hluav Taws, Pa Luam Yeeb, thiab Kev Lom Zem (FST):** Rau cov nkoj tub rog, dav hlau, thiab cov khoom siv tseem ceeb, kev nyab xeeb yog qhov tseem ceeb. Cov tshuaj phenolic feem ntau qhia tias muaj **kev tsim pa luam yeeb tsawg** thiab **kev lom tsawg** thaum raug hluav taws, ua rau lawv yog cov khoom siv nyiam rau sab hauv tsev, cov kav dej hluav taws xob, thiab cov vaj huam sib luag sib xyaw uas kev nyab xeeb ntawm tib neeg yog qhov txhawj xeeb.

Cov Ntawv Thov Tub Rog thiab Aerospace Tseem Ceeb

Qhov ua tau ntau yam ntawmcov PMCs uas muaj zog dua los ntawm cov xov txiavtso cai rau lawv siv rau hauv ntau lub luag haujlwm tseem ceeb:

* **Cov Cheebtsam ntawm Rocket thiab Missile:** Siv rau kev rwb thaiv cov khoom ntawm lub cev muaj zog thiab hauv cov qhov nozzle throats kom tswj tau cov cua sov siab thaum lub sijhawm tua tawm.

* **Sab Hauv thiab Qauv ntawm Lub Dav Hlau:** Cov khoom siv rau lub dav hlau, qhov twg cov khoom siv tsis hnyav thiab ua raws li FST yog qhov tseem ceeb rau kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.

* **Cov Khoom Siv Sib Txhuam:** Siv rau hauv cov tshuab nres rau cov tsheb tub rog hnyav hauv av thiab cov dav hlau vim lawv tiv taus cua sov thiab kev hnav zoo heev.

* **Cov Tsev Hluav Taws Xob thiab Khoom Siv Hluav Taws Xob:** Lawv lub zog dielectric siab thiab qhov ruaj khov ua rau lawv zoo tagnrho rau kev khaws cov khoom siv hluav taws xob rhiab heev uas yuav tsum ua haujlwm tau zoo hauv qhov chaw hluav taws xob lossis qhov kub thiab txias.

Qhov Zoo ntawm Chopped Molding Compound

Kev tsim cov khoom los ntawm cov khoom sib xyaw ua ke muab qhov zoo dua hauv kev tsim khoom tiv thaiv: **kev ywj pheej tsim. ** Cov khoom sib xyaw tuaj yeem raug nias lossis txhaj tshuaj pwm rau hauv cov duab nyuaj, tsis sib xws uas nyuaj rau ua tiav nrog cov khoom siv fiber ntau tas mus li. Lub peev xwm no los pwm cov khoom sib xyaw, muaj zog, thiab ruaj khov rau cov lus qhia tub rog ua kom cov khoom siv ruaj khov ua lub hauv paus tseem ceeb rau kev siv tshuab tub rog thiab aerospace.

Cov khoom siv tiv thaiv zoo hauv Suav teb Beihai uas ua tau raws li cov qauv kev lag luam tiv thaiv. Tiv tauj peb kom paub seb peb cov ntaub ntawv tuaj yeem txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm koj cov khoom tseem ceeb.
