Glass Fiber Mats
1.Strand Mat e Khaotsoeng (CSM)Glass fiber roving(ka linako tse ling e boetse e tsoela pele ho roving) e khaoloa ka bolelele ba 50mm, ka mokhoa o sa reroang empa ka mokhoa o ts'oanang o behiloe holim'a lebanta la letlooeng la conveyor. Joale ho sebelisoa sekontiri sa emulsion, kapa se tlamisa phofo e tšeloa ka lerole, ebe thepa e futhumatsoa le ho phekoloa ho etsa moalo o khaotsoeng. CSM e sebelisoa haholo-holo ho beha matsoho, ho etsa liphanele tse tsoelang pele, ho bopa ha lifensetere, le lits'ebetso tsa SMC (Sheet Molding Compound). Litlhoko tsa boleng ba CSM li kenyelletsa:
- Boima ba sebaka se ts'oanang ka bophara.
- Kabo e tšoanang ea likhoele tse khaotsoeng holim'a moseme o se nang li-voids tse kholo, le kabo ea li-binder tse tšoanang.
- Matla a mahareng a ommeng.
- E babatsehang resin wetting le ho kenella ka hare.
2.Continuous Filament Mat (CFM)Li-filaments tse tsoelang pele tsa khalase tse entsoeng nakong ea ho taka kapa tse sa tsoakoang ho tloha liphutheloana tsa roving li behoa fatše ka mokhoa oa setšoantšo sa robeli holim'a lebanta la letlooeng le tsoelang pele 'me le tlamisoa ka phofo e kopanyang. Kaha likhoele tsa CFM li ntse li tsoela pele, li fana ka matlafatso e ntle ho lisebelisoa tse kopaneng ho feta CSM. E sebelisoa haholo-holo ho pultrusion, RTM (Resin Transfer Molding), ho bopa mokotla oa khatello, le mekhoa ea GMT (Glass Mat Reinforced Thermoplastics).
3.Surfacing MatLihlahisoa tsa FRP (Fiber Reinforced Plastic) hangata li hloka lera le nang le resin e ngata, eo hangata e finyelloang ho sebelisoa khalase ea alkali e mahareng (C-glass) e holimo. Kaha 'mete ona o entsoe ka khalase ea C, o fana ka FRP ka khanyetso ea lik'hemik'hale, haholo-holo ho hanyetsa acid. Ho feta moo, ka lebaka la bosesaane ba eona le bophara bo botle ba fiber, e khona ho monya resin e ngata ho etsa lesela le nang le resin e ngata, e koahelang sebopeho sa lisebelisoa tse matlafatsang tsa khalase (joalo ka roving e lohiloeng) le ho sebetsa joalo ka bokaholimo.
4.Hlokahala MatE ka aroloa ho Chopped Fiber Needled Mat le Continuous Filament Needled Mat.
- Fiber e Hloekileng e Hlokahala Mate entsoe ka ho poma faeba ea khalase ka bolelele ba 50mm, e behoe ka mokhoa o sa reroang holim'a substrate e neng e behiloe holim'a lebanta la conveyor, ebe e e hlama ka linale tse hlabang. Linale li sutumelletsa likhoele tse khaotsoeng ka har'a substrate, 'me li-barbs li boetse li hlahisa likhoele tse ling holimo, li etsa sebopeho sa mahlakore a mararo. Substrate e sebelisoang e ka ba lesela le lohiloeng le sa tsitsang la khalase kapa likhoele tse ling. Mofuta ona oa 'mate o hlokahalang o na le sebopeho se kang sa maikutlo. Tšebeliso ea eona ea mantlha e kenyelletsa lisebelisoa tsa ho kenya mocheso le li-acoustic, lisebelisoa tsa lesela le lisebelisoa tsa ho sefa. E ka boela ea sebelisoa tlhahiso ea FRP, empa FRP e hlahisoang e na le matla a tlaase le sebaka se fokolang sa kopo.
- E Tsoelang Pele Filament Hlokahala Mate entsoe ka ho lahlela likhoele tsa fiber tse sa khaotseng tsa khalase holim'a lebanta le sa khaotseng la letlooeng ho sebelisa sesebelisoa se hasang likhoele, 'me se lateloe ke ho hlajoa ka lepolanka la nale ho etsa 'mete o nang le sebopeho se lohiloeng sa mahlakore a mararo. 'Mate ona o sebelisoa haholo-holo ha ho etsoa lipampitšana tse matlafalitsoeng tsa khalase tsa thermoplastic.
5.E rokotsoe MatLikhoele tse khaotsoeng tsa khalase tse tlohang ho 50mm ho isa ho 60cm ka bolelele li ka rokelloa hammoho ka mochini o rokang ho etsa mathete a sehiloeng a faeba kapa lesela le lelelele la fiber. Ea pele e ka nka sebaka sa CSM e tlamahanoang ke setso lits'ebetsong tse ling, 'me ea morao-rao e ka nka sebaka sa CFM ho isa bohōleng bo itseng. Melemo ea bona e tloaelehileng ke ho ba sieo ha li-binders, ho qoba tšilafalo nakong ea tlhahiso, ts'ebetso e ntle ea ho kenya resin, le litšenyehelo tse tlase.
Lisebelisoa tsa Glass Fiber
Lintlha tse latelang li kenyelletsa masela a fapaneng a fiber a khalase a lohiloeng kalikhoele tsa fiber tsa khalase.
1.Lesela la KhalaseLesela la khalase le hlahisoang Chaena le arotsoe ka mefuta ea alkali-free (E-glass) le mefuta ea alkali e mahareng (C-glass); tlhahiso e ngata ea kantle ho naha e sebelisa lesela la khalase le se nang alkali la E-GLASS. Lesela la khalase le sebelisoa haholo-holo ho hlahisa li-laminate tse fapaneng tsa motlakase, liboto tsa potoloho tse hatisitsoeng, 'mele oa likoloi, litanka tsa polokelo, liketsoana, hlobo, joalo-joalo. Litšobotsi tsa lesela li laotsoe ke thepa ea fiber, bokaholimo ba marang-rang le botenya, sebopeho sa khoele le mohlala oa weave. Boima ba khoele le khoele bo khethoa ke sebopeho sa khoele le mokhoa oa ho loha. Motsoako oa sekhomaretsi sa warp le weft le sebopeho sa khoele se etsa qeto ea hore na lesela le na le litšobotsi life, joalo ka boima, botenya le matla a ho robeha. Ho na le mekhoa e mehlano ea motheo ea ho loha: thota (e ts'oanang le roving e lohiloeng), twill (ka kakaretso ± 45°), satin (e ts'oanang le lesela la unidirectional), leno (tse ka sehloohong tse lohang bakeng sa letlooeng la fiber ea khalase), le matts (tse tšoanang le lesela la oxford).
2.Glass Fiber TapeE arotsoe ka theipi e lohiloeng (bohale ba selvage) le theipi e sa lohiloeng (bohale bo robehileng). Mokhoa o ka sehloohong oa ho loha o hlakile. Theipi ea fiber ea khalase e se nang alkali hangata e sebelisoa ho etsa likarolo tsa lisebelisoa tsa motlakase tse hlokang matla a phahameng le thepa e ntle ea dielectric.
3.Glass Fiber Unidirectional Fabric
- Unidirectional Warp Fabricke lesela la satin le entsoeng ka likhoele tse 'nè le robehileng kapa le lohiloeng ka likhoele tse mahoashe le likhoele tse ntle tsa weft. Sebopeho sa eona ke matla a phahameng haholo-holo ka lehlakoreng la warp (0 °).
- Ho boetse ho na leGlass Fiber Unidirectional Weft Fabric, e fumaneha ka mefuta e 'meli ea warp-lohiloeng le e lohiloeng. E khetholloa ka likhoele tse mahoashe le likhoele tse ntle tsa warp, tse nang le likhoele tsa khalase tse shebaneng haholo le tsela ea weft, e fanang ka matla a holimo ho tataiso ea weft (90 °).
4.Glass Fiber 3D Fabric (Stereoscopic Fabric)Masela a 3D a amana le masela a planar. Likarolo tsa bona tsa sebopeho li fetohile ho tloha ho karolo e le 'ngoe le tse peli ho ea ho tse tharo, ho fana ka lisebelisoa tse kopantsoeng tse matlafalitsoeng ke tsona botšepehi bo botle le ho lumellana, ho ntlafatsa haholo matla a ho kuta a interlaminar le mamello e khahlanong le tšenyo ea lihlopha. Li ile tsa ntlafatsoa ho fihlela litlhoko tse khethehileng tsa mafapha a sefofane, lifofane, libetsa le likepe, 'me kopo ea tsona e se e atolohile ho kenyelletsa likoloi, thepa ea lipapali le thepa ea bongaka. Ho na le mekhahlelo e mehlano e meholo: masela a lohiloeng a 3D, masela a lohiloeng a 3D, masela a 3D a orthogonal le a non-orthogonal a non-crimp, masela a lohiloeng a 3D, le mefuta e meng ea masela a 3D. Libopeho tsa masela a 3D li kenyelletsa block, columnar, tubular, hollow truncated cone, le mefuta e fapaneng ea botenya bo sa tloaelehang.
5.Glass Fiber Preform Fabric (Lesela le bōpehileng joaloka)Sebopeho sa masela a preform se tšoana haholo le sebopeho sa sehlahisoa seo ba reretsoeng ho se tiisa, 'me se tlameha ho lohuoa holim'a liloele tse inehetseng. Masela a bōpehileng joaloka symmetrical a kenyelletsa: likatiba tse chitja, likhoune, likatiba, masela a bōpehileng joaloka dumbbell, joalo-joalo. Libopeho tse sa tšoaneng tse kang mabokose le mekoloko ea likepe le tsona li ka hlahisoa.
6.Glass Fiber Core Fabric (Lesela le Okang ka Botenya)Lesela la mantlha le na le masela a mabeli a bapileng a hokahantsoeng ka likhoele tse otlolohileng tsa longitudinal. Sebōpeho sa eona sa mahlakore a mararo se ka ba khutlo-tharo, khutlonnetsepa kapa khekhe ea linotši.
7.Lesela la Glass Fiber Stitch-Bonded (Knitted Mat or Woven Mat)E fapane le masela a tloaelehileng le a tloaelehileng a mathe. Lesela le tloaelehileng ka ho fetisisa le kopantsoeng le stitch le etsoa ka ho koahela lesela le le leng la khoele e tsoelipanang le lesela le le leng la khoele ea weft, ebe lea li kopanya ho etsa lesela. Melemo ea masela a kopantsoeng le stitch a kenyelletsa:
- E ka eketsa matla a ho qetela, matla a anti-delamination tlas'a tsitsipano, le matla a flexural a FRP laminates.
- E fokotsa boima baLihlahisoa tsa FRP.
- Sebaka se bataletseng se etsa hore sebaka sa FRP se be bonolo.
- E nolofatsa ts'ebetso ea ho beha matsoho le ho ntlafatsa tlhahiso ea basebetsi. Lintho tsena tse matlafatsang li ka nka sebaka sa CFM ho FRP le RTM, hape e ka nka sebaka sa roving e lohiloeng ka tlhahiso ea phala ea FRP ea centrifugal.
