1. Ifeliti yenaliti

I-Needle felt yahlulwe yaba yi-needle felt eqoshiweyo kunye ne-needle felt eqhubekayo. I-needle felt eqoshiweyo kukusika i-glass fiber ejikelezayo ibe yi-50mm, ngokungenanjongo iyibeke kwi-substrate ebekwe kwi-conveyor belt kwangaphambili, uze usebenzise inaliti enemivalo ukubhoboza inaliti, kwaye inaliti iya kugqobhoza i-fiber eqoshiweyo kwi-substrate. Kwaye i-crochet hook ivelisa ezinye ii-fibers ukuze zenze isakhiwo esinemilinganiselo emithathu. I-substrate esetyenziswayo inokuba ngelaphu elincinci le-glass fiber okanye ezinye ii-fibers, kwaye le needle felt inemvakalelo ethambileyo. Ukusetyenziswa kwayo okuphambili kubandakanya ukufudumala kobushushu kunye nezixhobo zokukhusela isandi, izixhobo zokuvala ubushushu, izixhobo zokucoca, kwaye ingasetyenziswa nakwimveliso ye-FRP, kodwa amandla e-FRP aphantsi kwaye umda wokusetyenziswa ulinganiselwe. Olunye uhlobo lwe-needle felt eqhubekayo yi-felt apho ii-strings zeglasi eziqhubekayo ziphoswa ngokungacwangciswanga kwi-continuous mesh belt ngesixhobo sokuphosa ucingo, uze ufake i-needle kwi-needle plate ukuze kwenziwe isakhiwo esinemilinganiselo emithathu apho ii-fibers zidityaniswe khona. Olu hlobo lwe-felt lusetyenziswa kakhulu ekuveliseni amaphepha e-thermoplastic aqinisiweyo e-glass fiber.

2. I-Fiberglass Chopped Strand Mat - Isixhobo sokubopha umgubo
Iifilamenti zeglasi eziluhlaza ezenziwe ngexesha lenkqubo yokuzoba okanye iifilamenti eziluhlaza eziphuma kwityhubhu yefilamenti eluhlaza zifakwa kwibhanti yemesh ehambayo rhoqo kumfanekiso wesi-8 kwaye zibotshelelwe ngeglue. Ifayibha ekwimathi yefayibha yeglasi eqhubekayo iyaqhubeka, ngoko ke inefuthe elingcono lokuqinisa kwizinto ezidityanisiweyo.

3.Iglasi yefayibhaUmati onqunqiweyo – Isibopheleli se-emulsion
Sika ifayibha yeglasi (ngamanye amaxesha sebenzisa i-roving engajijwanga) ibe bubude obuyi-50mm, uyisasaze ngokungacwangciswanga kodwa ngokulinganayo kwibhanti ye-mesh, uze ufake i-emulsion adhesive okanye i-spray powder binding agent ukuze uyifudumale kwaye uyiqinise kwaye uyibophe kwi-short Cut raw silk felt. Ii-strand mats ezinqunqiweyo zisetyenziswa kakhulu ekubekeni ngesandla, ekwenzeni iibhodi eziqhubekayo kunye nokubumba ucinezelo kunye neenkqubo ze-SMC. Iimfuno zomgangatho wee-strand mats ezinqunqiweyo zezi zilandelayo: ①Umgangatho wendawo uyafana kwicala lobubanzi; ②Ii-strand ezinqunqiweyo zisasazwa ngokulinganayo kumphezulu we-mat ngaphandle kwemingxuma emikhulu, kwaye i-binder isasazwa ngokulinganayo; ③Inamandla e-mat eyomileyo aphakathi; ④Igqwesile Ukungena kwe-resin kunye nokuvuleka kwayo.
