O le sui fai ata o le vaega autu lea o le fiber fiber infiltrant, e masani ona faʻamauina mo le 2% i le 15% o le vaega tele o le infiltrant formula, o lana matafaioi o le faʻapipiʻiina lea o le fiber tioata i fusi, i le gaosiga o le alava, ina ia maua ai e fusi fiber se tikeri lelei o le maaa, faʻapipiʻiina, e faʻafetaui ai mea e manaʻomia mulimuli ane. O mea e masani ona faʻaaogaina ata tifaga i totonu o faʻapipiʻi faʻapipiʻi fiber tioata o polymers, e aofia ai resini epoxy, polyurethane, polyester, resins phenolic, faʻasalalau polypropylene suiga, poʻo emulsions. O le fa'atinoga o mea fai ata tifaga e fa'alagolago lava i le fausaga mole mole ma le mamafa mole o le polymer. Mo lea lava sui fai ata tifaga, o le malo oalava tioatae mafai ona faʻatonutonuina e le mamafa mole mole o le sui fai ata tifaga, ma o se sui fai ata tifaga ma maualuga mole mamafa mamafa o le ai ai se stiffness maualuga atu o le alava tioata, lea e talafeagai mo togafitiga luga ofa'amalosia oloa fa'alava tioata tipi, a'o se mea e fai ata tifaga ma le mamafa mole mole maualalo e talafeagai mo le gaosiga o vulu e fa'aaogaina i le viliina ma le tosoina. Epoxy resin polymers o loʻo i ai aliphatic hydroxyl, ether, ma vaega epoxy, ma o loʻo i ai le malosi faʻamalositino i le va o vaega polar i le epoxy film-forming agents, o lea e lelei ai le pipii ma le faʻapipiʻiina o aʻafiaga i filo tioata;

E le gata i lea, o le vaega epoxy i totonu o le epoxy film-forming agent e mafai ona tali atu i le vaega hydroxyl terminal, vaega carboxyl terminal, vaega amino terminal, ma isi vaega toaaga i palasitika inisinia e pei o PBT, PET, PA, PC, ma isi, e faʻaleleia le malosi faʻafesoʻotaʻi i le va o le fiber tioata ma le resin. O vailaʻau faʻapipiʻi ata polyester o loʻo i ai le tele o vaega o le ester, faʻamaʻi kemisi unsaturated, ma vaega hydrophilic i le filifili autu, ma o latou faʻatinoga e faʻalagolago i le ituaiga o vailaʻau ma le ava o loʻo faʻaaogaina i le faʻaogaina o le polyester ma le fua faatatau. A o le resin faavae o le unsaturated polyester resin, o le unsaturated fusiua lua i le polyester film-fausia sui e mafai ona polymerize ma cross-sootaga faatasi ma fusi e lua i le resin faavae e fausia ai se sootaga kemikolo malosi po o le entanglement faaletino, lea e faaleleia ai le malosi sootaga interfacial. Polyester film-forming agents e masani lava ona lelei le susu ma le penetration mea ma o le mea lea e faʻaaogaina e avea ma suauʻu susu i pultrusion, winding, spraying, chevron, ma isi oloa. O le polyurethane film-forming agent molecular filifili o loʻo i ai le toe faia o le carbamate, o le i ai o nei vaega polar e mafai ai e le polyurethane i le fiber tioata ona fusia lelei, o vaega vaivai ma faigata mole mole o le tuʻufaʻatasia o le maualuga o le elasticity ma le abrasion resistance, i le taimi lava e tasi, polyurethane i le vaega isocyanate e mafai ona infiltrated ma le faʻaogaina o le matrix i le soʻo faʻapipiʻi, faʻaleleia le faʻafesoʻotaʻi matrix ma faʻamalosia le faʻafesoʻotaʻi matrix. le faatinoga omea tu'ufa'atasioloa.
