Ziziphi iiNzuzo zokuSebenza eziQhelekileyo zeFRTP?

IFayibha Eyongeziweyo kwiThermoplastic Composites (I-FRTP)

 

I-Fiber-reinforced thermoplastic composite materials ziyinxalenye ebalulekileyo yemathiriyeli edibeneyo. Iintlobo ezahlukeneyo zeerasi ze-thermoplastic ziqiniswaimicu yeglasi(GF),iifayibha zekhabhoni (CF), iifiber aramid (AF) kunye nezinye izinto zefiber. I-fiber-reinforced thermoplastic composites ezikumgangatho ophezulu zineempawu ezintle ezifana nokuqina okuphezulu, ukumelana nokugqwala kunye nokumelana nokukhathala, inkqubo yokubumba elula, umjikelo omfutshane, izinga eliphezulu lokusetyenziswa kwezinto (akukho nkunkuma), kwaye akukho mfuneko yokugcina ubushushu obuphantsi, kwaye ibe luphando. hotspot kushishino lwemathiriyeli.

 

Iinzuzo zokwenziwa komsebenzi eziqhelekileyo zeFRTP

 

I-Thermoplastic composite FRTP isetyenziswe amashumi eminyaka. Xa kuthelekiswa neecomposites ze-thermosetting ezifana ne-phenolic resin, i-urea-formaldehyde resin, i-epoxy resin, kunye ne-polyurethane, i-thermoplastic composites ineempawu ezizodwa:

 

◆Ukuxinana okuphantsi kunye namandla aphezulu:Ubuninzi be-FRTP yi-1.1-1.6g / cm3, eyi-1 / 5-1 / 7 kuphela yensimbi, i-1 / 3-1 / 4 ilula kune-FRP ye-thermosetting, kwaye inokufumaneka ngeyunithi encinci Amandla aphezulu omatshini kunye ibakala lesicelo.

 

◆Iqondo elikhulu lenkululeko kuyilo lokusebenza: Iipropathi ezibonakalayo, iipropathi zekhemikhali, kunye neepropathi zoomatshini ze-FRTP ziyilwe ngokukhetha okufanelekileyo kweentlobo zemathiriyeli ekrwada, umlinganiselo, iindlela zokusetyenzwa, umxholo wefayibha kunye neendlela zokubeka. Kukho izinto ezininzi, ezona zibalulekileyo ziquka i-polyetherketoneketone (PEKK), i-polyetheretherketone (PEEK), i-polyphenylene sulfide (PPS), inayiloni (PA), i-polyetherimide (PEI), njl. nayo inkulu kakhulu.

 

◆Iimpawu zobushushu: Ubushushu bokusetyenziswa ngokubanzi kweplastiki yi-50-100℃, kwaye inokunyuswa ukuya kuthi ga kwi-100℃ emva kokuqinisa ngefiber yeglasi. Ukushisa kokushisa kwe-PA6 yi-65 ° C, kwaye emva kokuqiniswa nge-30% ye-fiber yeglasi, ubushushu bokushisa ubushushu bunokunyuswa ukuya kwi-190 ° C. Ukumelana nobushushu bePEEK kufikelela kuma-220°C. Emva kokuqiniswa nge-30% yefiber yeglasi, ubushushu bokusebenza bunokunyuswa ukuya kuma-310 ° C. Izinto ezihlanganisiweyo ze-Thermosetting azikwazi ukufikelela ukuxhathisa ukushisa okuphezulu.

 

◆Ukunganyangeki komhlwa kwiikhemikhali: Ikakhulu igqitywe ngokusebenza kwezinto ze-matrix. Kukho iintlobo ezininzi ze-thermoplastic resins, kwaye i-resin nganye ineempawu zayo zokuchasana ne-corrosion. Ngoko ke, i-resin ye-matrix inokukhethwa ngokuhambelana nendawo yokusetyenziswa kunye neemeko eziphakathi kwezinto ezidibeneyo. Ngokubanzi, inokuhlangabezana neemfuno zokusetyenziswa. Ukumelana namanzi kwe-FRTP kwakhona kungcono kunoko kwe-thermosetting composite.

 

◆Iimpawu zombane: I-FRTP ngokubanzi ineempawu ezilungileyo ze-dielectric, ayibonisi amaza erediyo, kwaye ihambisa ii-microwaves kakuhle. Ekubeni izinga lokufunxa kwamanzi le-FRTP lincinci kunelo le-FRP ye-thermosetting, iimpawu zayo zombane zingcono kunokugqibela. Emva kokongeza izinto eziphathekayo kwi-FRTP, inokuphucula i-conductivity yayo kwaye ithintele ukuveliswa kombane ongatshintshiyo.

 

◆Inkunkuma inokuphinda isetyenziswe: I-FRTP inokuphinda icutshungulwe kwaye yenziwe, inkunkuma kunye nentsalela inokuphinda isetyenziswe, kwaye iimpawu ezibonakalayo kunye nezomatshini azitshintshi kakhulu, kwaye aziyi kubangela ukungcoliseka kwendalo. iimfuno zokusingqongileyo.
