Problems solved by technology

[0002] At present, glass fiber reinforced plastic cylinders for hollow composite insulators are generally produced by wet winding after glass fibers are soaked in epoxy resin. Since the winding process is not vacuum treated, tiny bubbles and local white spots will inevitably exist after curing, resulting in low yield and poor quality. Hidden dangers, research and development and production of higher-quality FRP cylinders, and improving product quality have become an urgent matter to be solved

Embodiment 1

[0026] A dry-process winding vacuum-impregnated fiberglass cylinder manufacturing process, comprising the following steps:

[0027] S1: laying polyester cloth in advance, performing weaving winding and hoop winding in sequence;

[0028] S2: Assembling the vacuum dipping system;

[0029] S3: Vacuum dipping; vacuum dipping speeds up the dipping speed and improves the uniformity of dipping. Not only is the process simple and easy to operate, but it can also greatly improve production efficiency, reduce production costs, and obtain FRP cylinders with excellent comprehensive performance.

[0030] S4: curing demoulding;

[0031] S5: The blank after demolding is processed into a finished product.

[0032] In step S1, 1 mm polyester cloth is spread.

[0033] When paving, 5 layers of 0.2mm thick polyester cloth are laid by flat winding.

[0034] In step S1, glass fiber filaments are used for weaving and winding, the winding angle is 40 degrees, and when the diameter of the finished...

Abstract

The invention discloses a glass fiber reinforced plastic barrel manufacturing process which comprises the following steps: pre-spreading polyester fabric, and sequentially performing woven winding andhoop winding; assembling a vacuum gum dipping system; performing vacuum gum dipping; curing and de-moulding; and processing de-moulded blank into a finished product. The glass fiber reinforced plastic barrel manufacturing process solves the problem of micro gas bubbles and white spots inside, improves product quality, and eliminates hidden trouble in equipment electrified operation.

Description

technical field [0001] The invention relates to the field of composite material preparation, which is used for the manufacture of glass fiber reinforced plastic cylinders for hollow composite insulators in power systems, in particular to a manufacturing process for glass fiber reinforced plastic cylinders. Background technique [0002] At present, FRP cylinders for hollow composite insulators are generally produced by wet winding after glass fibers are soaked in epoxy resin. Since the winding process is not vacuum treated, tiny bubbles and local white spots will inevitably exist after curing, resulting in low yield and poor quality. Hidden dangers, the development and production of higher-quality FRP cylinders, and the improvement of product quality have become an urgent matter to be solved. Contents of the invention [0003] The purpose of the present invention is to develop a new production process, solve the problem of micro-bubbles and white spots inside the glass fibe...
