Abstract

The invention relates to a pultrusion production method and appliance of fiber reinforced composite bending profiles. The production method comprises the working procedures of feeding yarns, arrangingfiber, gumming, preforming, solidifying and forming, pulling and cutting. The appliance for realizing the pultrusion production method comprises a creel, a fiber arrangement board, a guide roller, aresin glue tank, a preforming die, a solidifying die, a first bending and pulling device, a second bending and pulling device, a cutting device and a rack, wherein the yarns are preliminarily heated,extruded, solidified and formed in the solidifying die and then are pulled out of the die by the bending and pulling devices so as to move along with a circular curve track, and the yarns are cut so as to form the bending profiles after reaching the proper length. The method has the advantages of simplicity and clearness, a production tool is simple and is easy to implement, and the production method is suitable for pultrusion production of the bending profiles with different radii.

Description

technical field [0001] The invention relates to a pultrusion production method and equipment for a fiber-reinforced composite material curved profile, and belongs to the field of fiber-reinforced composite material structures. Background technique [0002] The pultrusion molding process is a method of continuously producing fiber-reinforced composite profiles. It impregnates untwisted fiber rovings on the creel or other continuous reinforcing materials, polyester surface mats, etc., and then passes them through a molding die of a certain shape. , and make it out of the mold continuously after curing in the mold, thus forming an automated production process for pultrusion products. The advantages of pultrusion are: the production process is fully automated and controlled, the production efficiency is high, the dipping is carried out under tension, and the role of the reinforcing material can be fully exerted, the product has high strength, and there is no leftover material in...
