Method for impregnating continuous fiber material with molten thermoplastic for producing fiber-reinforced plastic profile, involves setting minimum distance of converging surfaces of fiber material higher than fiber thickness

摘要

#CMT# #/CMT# A plastic bath (11) is formed in pockets (10,29) provided between the two converging surfaces (6,7,26). The fiber materials (12,25) pulled within the pocket are impregnated with the plastic bath. The minimum distance of converging surfaces at an exit point of the fiber material is set 50% more than the thickness of the fiber material. A horizontally defined plane is extended through an axis (5) of rotation of the rollers (2). The peripheral speed of surfaces of pocket is directed in extraction direction of the fiber material. #CMT# : #/CMT# An independent claim is included for a pultrusion process for producing fiber-reinforced plastic profile. #CMT#USE : #/CMT# Method for impregnating continuous fiber material with molten thermoplastic used in pultrusion process (claimed) for producing fiber-reinforced plastic profile. #CMT#ADVANTAGE : #/CMT# The improved process for impregnating continuous fiber material with molten thermoplastic can be achieved. The fiber materials are oriented in the direction of load, and hence high tensile strength is achieved in load direction. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic views of the device for impregnating continuous fiber material with molten thermoplastic. 2 : Roller 5 : Rotation axis of rollers 6,7,26 : Converging surfaces 10,29 : Pockets 11 : Plastic bath 12,25 : Fiber materials.
