High Strength Filament Wound Carbon Fiber Tube Special Formula Resin

High Strength Filament Wound Carbon Fiber Tube Special Formula Resin

Filament Wound Carbon Fiber Tube Introduction

Our tube is roll-wrapping tube, not pultrusion tube, roll-wrapping tube have the longitude and weft yarn, but pultrusion tube only have the longitude, not weft yarn, therefore, the strength is not as well as roll tubes. Our tubing is manufactured using precision ground mandrels and closely monitored material quality. Our goal is to provide customers with high quality tubing balanced with reasonable pricing.

Filament Wound Carbon Fiber Tube Specification

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.

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.

(3) half dry winding After half dry winding is fiber rubber, en route to the winding to the mandrel, increases

a set of drying equipment, solvent to remove from the rubber yarn, compared with the dry method,

dispense with presoak glue process and equipment;Compared with wet method, can make the products in

the bubble content is lower.Three methods of winding, wet winding used in the most common;Dry winding

is used only for high performance and high precision of cutting-edge technology.
