Breaking Length Limits, Ushering in a New Era of Manufacturing
In the field of high-end composite materials, length has always been a core measure of manufacturing capability. Traditional CF/PEEK unidirectional tapes, limited by process bottlenecks, could often only provide discontinuous products of tens to hundreds of meters, with frequent joints, performance fluctuations, and low efficiency plaguing the industry.
Now, Jiangsu Junhua HPP Special Polymer Materials Co., Ltd. proudly introduces a continuous 1000-meter CF/PEEK prepreg tape (LU-CF/PEEK)—this is not simply a numerical increase, but a revolutionary leap in thermoplastic prepreg manufacturing technology.
From the first meter to the thousandth meter, fiber tension remains consistent, resin distribution uniform, and mechanical properties stable.
This means aerospace structural parts can achieve seamless integral forming, and automated placement and winding equipment can run continuously for hours without needing to stop for roll changes. The birth of kilometer-level continuous tape completely breaks the traditional model of “segmented manufacturing and splicing use,” paving the way for large-scale industrial applications.
01. Slurry Process Empowerment: Every Meter is a Promise of Quality
Behind Jiangsu Junhua HPP’s achievement of 1000-meter continuous length is the precision support of the slurry preparation process. We use PEEK ultra-fine powder and additives specially developed by Junhua HPP for unidirectional tape to formulate a stable slurry. Through mechanical vibration to spread the carbon fiber tows evenly, and then through multiple precision processes including impregnation, drying, pre-melting, and flat plate forming, the tape is produced.
Compared with the traditional hot-melt method, the slurry process offers unique advantages:
Resin wetting, coating, and dispersion of fibers are more thorough, with lower porosity;
The entire production line is equipped with online concentration detectors, online tension adjustment and monitoring equipment, and thickness feedback systems, ensuring that from the start to the end, the fiber weight content is always maintained at the golden ratio of 62-67%, and thickness tolerance is controlled within ±0.02mm.
More importantly, our winding system uses adaptive tension control technology, ensuring that even kilometer-long tape rolls remain smooth and wrinkle-free with no edge damage.
Every meter of tape undergoes strict online inspection to ensure that key indicators such as tensile strength, flexural strength, and interlaminar shear strength meet aerospace-grade standards.
02. From Laboratory to Industrialization: Comprehensive Expansion of Application Scenarios
The 1000-meter continuous length brings not only a leap in production efficiency but also unlimited expansion of application scenarios. Particularly noteworthy is that Junhua HPP’s LU-CF/PEEK can be customized in widths ranging from 2.0 to 300mm, with thicknesses covering 0.11–0.2mm specifications, perfectly matching various process routes such as autoclave molding, automated fiber placement, and filament winding. Whether you are an R&D institution conducting prototype trials or a manufacturing enterprise seeking mass production, the kilometer-level continuous tape provides seamless integration from “meter” to “kilometer.”
Aerospace field: It can be used to manufacture main load-bearing structures such as wing spars and fuselage frames several meters long, eliminating splice weak points and improving overall reliability.
Automotive industry: When combined with automated placement equipment, it enables high-speed continuous production of certain structural parts, shortening manufacturing cycles.
Marine engineering: Filament winding of ultra-long corrosion-resistant pipes and deep-sea risers becomes simple and efficient.
Medical device industry: Continuous extrusion molding of orthopedic implants and surgical instruments ensures product consistency and traceability.
03. Choose Kilometer-Level Continuous Tape, Choose Future Competitiveness
In the field of high-end composite materials, “continuity” represents reliability, and “length” symbolizes strength. Choosing our Junhua HPP 1000-meter LU-CF/PEEK gives you not just a roll of material, but a complete solution.
● Room temperature storage eliminates expensive cold chain logistics costs;
● Excellent secondary welding performance supports thermoplastic joining of complex structures;
● Recyclability aligns with green manufacturing trends;
● The reduction of joints brought by kilometer-level length directly reduces material waste and manual splicing costs.
We fully understand that at critical junctures such as aerospace certification, automotive mass production, and energy equipment upgrades, the stability and consistency of material supply are of utmost importance.
Therefore, from raw material screening to finished product delivery, we have established a full-process quality traceability system, ensuring that every kilometer-level tape roll is traceable and quality-assured. While your competitors are still worrying about joint quality, you have already gained the advantage with continuous kilometer-length high-quality tape.
Let us join hands and, with kilometer-level continuous manufacturing capability, jointly explore the infinite possibilities of thermoplastic composite material applications!
