Prepreg production line

continuous

As a kind of high performance engineering material, polyphenylene sulfide (PPS) has many advantages in performance. GPM's machinery adopts melt imprégnation process, which is différent from the conventional powder method and solution method. It can realize the continuous and stable molding production of PPS- unidirectional adhesive tape, and has the conditions for quantitative production. PPS high performance granule is extruded by melt plasticization through spécial high temperature extruder, It is quantitatively transported by the melt pump, and the thermoplastic is dispersed and impregnated and compounded with the continuous carbon fiber in the imprégnation mold.The width of the product is 300-600mm, and the thickness is 0.2-0.22mm. The specific gravity of CF and PPS is about 1:1. The UD tape produced has smooth surface, good imprégnation effect and uniform continuous fiber distribution.
