Carbon fiber winding of molding process

Winding molding process is soaked in resin adhesive solution of continuous fiber (or cloth belt, presoak

yarn) on winding to the mandrel according to certain rules, and then after curing, demoulding, obtain

products.According to the filament winding forming physical and chemical condition when the resin is

different, divided into dry winding, wet winding and half dry winding 3 kinds.(1) dry winding Dry winding

is adopted through presoak rubber processing presoak yarn or, on a winding machine after soften to

viscous flow winding onto the mandrel.Because of presoak yarn (or with) is a professional production,

to strictly control the resin content (accurate to 2%) and presoak yarn quality.Therefore, dry winding

can accurately control the quality of the product.Dry winding process is the biggest characteristic of high

production efficiency, winding speed can reach 100 ~ 100 m/min, winding machine cleaning, labor health

condition is good, high product quality.The downside is winding equipment is expensive, need to increase

in yarn manufacturing equipment, so the investment is bigger also, dry low interlaminar shear strength

of winding products.

1. The wet winding Wet winding is fiber cluster (yarn belt), glue, directly under tension control winding
2. Onto the mandrel.The advantages of wet winding for: (1) 40% lower cost than dry winding;(2) the
3. Product has good air tightness, because of the winding tension to squeeze bubbles, the excess
4. Resin adhesive liquid and fill gaps;(3) fiber arrangement good parallelism;(4) the wet winding, fiber
5. Resin adhesive solution, can reduce the fiber abrasion;5. High efficiency (up to 200 m/min).Wet
6. Winding faults as follows: (1) resin waste is big, poor operating environment;(2) gel content and
7. Quality of the finished product is not easy to control;(3) less available for wet winding resin varieties.
8. Half dry winding After half dry winding is fiber rubber, en route to the winding to the mandrel,
9. Increases a set of drying equipment, solvent to remove from the rubber yarn, compared with the
10. Dry method, dispense with presoak glue process and equipment;Compared with wet method, can

Filament Wound Tubing advantages

(1) can be according to the stress of the product design winding, can

give full play to the strength of the fiber;

(2) than high strength: generally speaking, a filament wound

pressure vessels with volume, compared with pressure of steel container, the weight can reduce

40 ~ 60%;

(3) high reliability: filament winding is easy to realize mechanization and automation of

production, process condition is determined, put out the product quality is stable and accurate;

(4) high efficiency: the mechanized or automated production, need operation workers less, winding speed (240

m/min), therefore, high labor productivity;

(5) the cost is low: in the same products, can be chosen

reasonable distribution of several kinds of materials (including resin, fiber and lining), make its

recombination, the best technical and economic effect.
