II.SurfaceChemicalTreatment

1.Corestep: Couplingagenttreatment.Ajan kouple silan yo itilize souvan (egzanp, KH-550, KH-560, A-174, elatriye) yo aplike.

2.Remak: Anpil twal fib vèr ki disponib nan komèsyal ak ajan renforcées (egzanp, twal tise nan dirèkroving) deja gen tretman sa a te konplete nan faktori, nan ki ka etap sa a kapab omèt. Sepandan, sa a ta dwe verifye.

III.DryingandPreheating

1.Drying/Moistureremoval: Twal fib vè trè igroskopik. Anvan enpregnasyon, li dwe seye a 80 ° C–120 ° C pou 1–2 èdtan pou diminye kontni imidite a anba a 0.1 %. Twal trete yo ta dwe. itilize imedyatman oswa estoke nan yon sikatè pou anpeche reabsòpsyon imidite. Imidite ap vaporize pandan geri, ki mennen nan bul, vid, ak lyezon entèfasyal febli.

2.Prechofaj: Pa obligatwa, men souvan itilize nan pwosesis tankou pultruzyon, bobinman filaman, ak RTM (transfermolding résine). Objektif la pou anpeche yon ogmantasyon brid nan viskozite nan resin lè kontak ak twal frèt, ki ta afekte tanperati ki mouye deyò.
