A kind of continuous winding fiberglass reinforced pipe preparation method

Abstract

The invention discloses a method for preparing a continuous winding FRP reinforced pipe. The method includes calculating the body layer of the continuous pipe (1) and the size and distribution of the reinforcing ribs (4) according to the design internal pressure and stiffness requirements, and reasonably distributing the reinforcing ribs The winding material (2) is linked with the reinforcing rib winding platform (3) and the coiled pipe production equipment to finally obtain the continuous winding reinforced pipe (5). The present invention replaces the traditional sand inclusion process with reinforcement, reduces the winding thickness of the coiled pipe body, improves the infiltration speed and production speed of the pipe body, and solves the layering problem faced by the traditional production process and the winding and blanking of the traditional equipment platform To solve the problem of insufficient platform width, the width of the inner and outer fiber winding layers can be shortened, and continuous winding pipes with higher rigidity and greater thickness can be produced in a limited equipment space.

Description

technical field [0001] The patent of the present invention relates to a preparation process of a reinforced rib tube, in particular to a production and manufacture process of a continuously wound FRP reinforced rib tube. Background technique [0002] The continuous winding production technology of FRP pipes is a new process technology in China. It can realize continuous and non-stop production by means of unique production equipment, and the product performance, production stability and production efficiency are better than fixed-length winding technology. [0003] The continuous winding molding process is to wind the inner core mold of the pipe in a continuous operation of a cam plate driven by a steel belt or other means to form a back and forth cycle, and then the resin, surface felt, continuous fibers, chopped fibers and / or quartz sand. Such raw materials are continuously layered by means of hoop winding, cutting and blanking according to a certain proportion, so as to r...
