Lay-up method

Abstract

The invention provides a hand lay-up molding method. The hand lay-up molding method comprises the following steps of S01: laying a base layer; S02: laying a glass fiber cloth layer on the base layer, and coating resin on the glass fiber cloth layer in a rolling manner, so as to enable the resin to permeate uniformly into the glass fiber cloth layer; S03: scraping the excessive resin after the step S02; S04: laying the glass fiber cloth layer in the step S03 to a position needing hand lay-up, then compacting, and finally tearing off the base layer.

Description

technical field [0001] The invention relates to the field of composite material molding, in particular to a hand lay-up molding method. Background technique [0002] In the production process of wind turbine blades, the front and rear edge reinforcement of the blade, the web edge, the bonding angle, the root baffle fixation and other components are hand lay-up parts, and these hand lay-up parts need to be manufactured through the hand lay-up molding process. [0003] The basic steps of the existing hand lay-up molding process are: workers manually apply resin to the fiber layer, and then paste the fiber layer with resin to the required position to complete the hand lay-up. The existing hand lay-up molding process has many disadvantages, such as molding quality depends on the worker's operating level and sense of responsibility, resin content control is difficult, etc. The quality of parts formed by hand lay-up molding is obviously lower than that of vacuum infusion molding,...
