Breaking through the length limit, ushering in a new era of manufacturing
In the field of high-end composite materials, length has always been the core measure of manufacturing capability. Traditional CF/PEEKUnidirectional belts are limited by process bottlenecks and can often only provide intermittent products ranging from tens to hundreds of meters. Frequent joints, performance fluctuations, and low efficiency have become persistent problems that plague the industry.
Now, Jiangsu Junhua Special Polymer Materials Co., Ltd. proudly launchesContinuous length of 1000 meters CF/PEEK prepreg tape (LU-CF/PEEK)This is not a simple numerical superposition, but a revolutionary leap in thermoplastic prepreg manufacturing technology.
From the first meter to the first kilometer,Consistent fiber tension, uniform resin distribution, and stable mechanical properties.
This means that aviation structural components can achieve seamless overall molding, and automated laying and winding equipment can operate continuously for several hours without stopping to change rolls. The birth of kilometer level continuous strip completely broke throughSegmented manufacturing and splicing for useThe traditional model has paved the way for large-scale industrial applications.
01
Mud process empowerment
Every meter is a quality commitment
Behind Jiangsu Junhua Co., Ltd. achieving a continuous length of 1000 meters is the precise support of the mud method preparation process. We use the PEEK ultrafine powder and additives specially developed by Junhua Unidirectional Belt to prepare a stable slurry. The carbon fiber bundles are uniformly unfolded through mechanical vibration, and then precision formed through multiple processes such as impregnation, drying, pre melting, and flat plate shaping.
Compared with traditional hot melt method, mud method endows unique advantages
Resin has more complete infiltration, coating and dispersion of fibers, and lower porosity;
The entire production line is equipped with online concentration detectors, online tension adjustment monitoring equipment, and thickness feedback systems to ensure that the fiber quality content is always maintained at the golden ratio of 62-67% from the beginning to the end, and the thickness tolerance is controlled within ± 0.02mm.
More importantly, our winding system adopts adaptive tension control technology, which can maintain flatness without wrinkles and edges without damage even when winding tapes up to kilometers long.
Every meter of strip undergoes strict online testing to ensure that key indicators such as tensile strength, bending strength, and interlayer shear strength meet aviation grade standards.

From laboratory to industrialization
Comprehensive expansion of application scenarios
The continuous length of 1000 meters not only brings a leap in production efficiency, but also infinite expansion of application scenarios.
Aerospace fieldIt can be used to manufacture main load-bearing structures such as wing beams and fuselage frames that are several meters long, eliminating weak joints and improving overall reliability.
automotive industryCombined with automatic laying equipment, high-speed continuous production of some structural components can be achieved, shortening the manufacturing cycle.
Ocean EngineeringThe winding molding of ultra long corrosion-resistant pipelines and deep-sea risers has become simple and efficient.
Medical device industryThe continuous extrusion molding of orthopedic implants and surgical instruments ensures product consistency and traceability.
Laying, winding and forming
Of particular note is Junhua's LU-CF/PEEKThe width can be customized within the range of 2.0-300mm, and the thickness covers specifications of 0.11-0.2mmPerfectly matched with various process routes such as hot press molding, automatic fiber laying, and winding molding. Whether you are a research and development institution conducting prototype testing or a manufacturing enterprise seeking large-scale production, kilometer level continuous strip can provide seamless connection from "meter" to "kilometer".
