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.
(2) the wet winding Wet winding is fiber cluster (yarn belt), glue, directly under tension control winding
onto the mandrel.The advantages of wet winding for: (1) 40% lower cost than dry winding;(2) the product
has good air tightness, because of the winding tension to squeeze bubbles, the excess resin adhesive
liquid and fill gaps;(3) fiber arrangement good parallelism;(4) the wet winding, fiber resin adhesive
solution, can reduce the fiber abrasion;5. High efficiency (up to 200 m/min).Wet winding faults as follows:
(1) resin waste is big, poor operating environment;(2) gel content and quality of the finished product is
not easy to control;(3) less available for wet winding resin varieties.
