JT-CFRT-650/700 fully incorporates the benefits of comparable equipment in Japan, Germany, Taiwan, and China, and is a high-efficiency prepreg compounding machine created and constructed through continuous refinement and perfection in the real manufacturing process.
Fiberglass yarn creel, yarn spreading, ceramics oven, dipping die, extrusion system, setting system, rewinding system, and other components comprise the total production process.
Creel for 192 spindle fibers
A fiber creel with 192 bobbins holds fiberglass woven roving. Each bobbin is attached to a driving shaft and is linked to a motor through pulleys and wire strands.
To make a cylindrical shape, all of the bobbins are positioned in order down the length of the creel.
The fiber creel should be able to rotate in both directions and have an adjustable angle from the horizontal at each position.
When stopped, the automatic brake function helps keep the yarn from becoming loose.
There are 96 spindles on each side. The paper tube is standard 3 inches in diameter, with a maximum diameter of 300mm.
Yarn spreading section
The yarn spreading comb is adjustable in the width direction, making it easy to change the width of the yarn.
Each piece is joined by joints and rests on the left and right threads’ adjustable link mechanism. Adjust width range is 3-6mm.
Traction is of the active friction kind, with a rubber roller of 250mm width and 900mm length.
Glass fiber roving is clamped using rubber rollers and steel rods.
The resin particles can be held in the hopper and fed into the extruder by a twin screw or a single screw.
They will then be fed into the barrel of the extruder via the extruder screwing tube.
Following mixing and kneading, the resin will be melted into a liquid mass at temperatures ranging from 100°C to 200°C.
It is heated, melted, and forced to flow out through the die by the high-speed revolving screw.
A creel, a separation system, a dipping system, a traction system, and a rewinding frame are common components of a melt impregnation apparatus.
The principle is to lay the continuous fiber behind the creel and equally force it into the separation system by adjusting the rollers.
The fibers are fully stretched and warmed by the unwinding roller before entering the impregnation system in the fiber separation system.
The molten resin infiltrates the fiber under the operation of high temperature and high pressure, and the prepreg is obtained by cooling and traction.
For solvent-resistant resins, melt impregnation is preferable.
The impregnating material is less volatilized, avoiding internal defects of high porosity induced by solvent volatilization, and is suited for the manufacture of crystalline resin prepreg tapes.
Edge trimmer and collector system for waste
The edge of the generated thermoplastic unidirectional tape is not neat when the resin and fiber are impregnated and compounded in the mold.
This difficulty is solved by the circular knife-trimming mechanism.
The trimmed scraps will be automatically rewinding to our traverse spooling machine, fitted with one on each side. On the side of the prepreg production line, a hand wheel is mounted to manually adjust the width of the waste edge.
Stand for rewinding
Jota Machinery’s strength has always been rewinding, and the double-winding stands have their own tension systems.
Each station’s maximum winding diameter is 1500mm, and its maximum load-bearing capability is 2000.00kg. For offloading, it must be paired with a row crane.
Two torque reduction motors regulate each of the two windings.
When the material roll in the working winding position exceeds the predetermined length, the alarm bell sounds, the winding motor in the other working position is started manually, and the material is manually cut off.
Roll the material onto the new station’s paper core to complete the winding of the second roll of material.
Stop the roll manually, lift it, replace the air shaft and paper core, and wait for the next station switch to achieve continuous roll change.
Each rewinding stand has a touch screen and independent continuous tension control, as well as a real-time display of equipment operation status and numerous control techniques.

Thermoplastic UD tapes have a carbon fiber reinforcing and are a high-performance elastomeric material.
The UD material is made by molding a polymer or other resin around a continuous reinforcing textile filament, such as carbon fiber or woven fiber, that is inserted in the resin matrix during the high pressure, high-temperature pre-impregnation process.
Unidirectional is shortened as UD. This means that one side of the tape is smooth and flat, while the other side has a texture comparable to that of woven materials such as cotton or wool.
The flat side is utilized to adhere to substrates, while the textured side is used to adhere to the surface of the substance being bonded.
UD tapes can be used to make robust and long-lasting connections between two materials or surfaces.
They’re also commonly utilized as an adhesive backing on carbon fiber prepregs before they’re cut into panels or strips for usage in items like aviation parts or automobiles.
