Entering a new era of industrial material upgrades, a new composite material that breaks traditional boundaries is quietly changing the production landscape of many high-end fields—JHFRTP Composites launches Continuous Basalt Fiber/Polyetheretherketone Unidirectional Prepreg (PEEKFRTP®BF-UD), becoming a trusted choice for demanding applications with multiple hardcore advantages.
Part.01Material Breakthrough: When “Volcanic Rock” Meets “Plastic”
PEEKFRTP®BF-UD Unidirectional Prepreg is a high-performance thermoplastic unidirectional prepreg, whose core lies in the precise combination of continuous basalt fiber (BF) and polyetheretherketone (PEEK).
Basalt fiber is made from natural basalt ore, offering excellent flame retardancy, high and low temperature stability, and natural insulation. Its mechanical strength far exceeds that of ordinary glass fiber, while it has lower moisture absorption and better resistance to acid and alkali corrosion compared to carbon fiber.
PEEK (Polyetheretherketone), as a benchmark in specialty engineering plastics, possesses outstanding impact resistance, creep resistance, and biocompatibility.
Through the synergistic effect of the two, PEEKFRTP®BF-UD Unidirectional Prepreg surpasses traditional carbon fiber/thermoset prepreg in terms of lightweight, mechanical stability, and long-term service reliability.
Part.02 Process Innovation: Slurry Process Precision Manufacturing
Junhua HPP adopts the Slurry Process precision manufacturing technique, using PEEK ultra-fine powder to prepare a stable aqueous slurry. The basalt fiber bundles are evenly spread through mechanical spreading rollers, and then undergo sequential steps such as impregnation, drying, pre-melting, and flat plate shaping.
Compared to traditional hot melt methods, the slurry process uses low-viscosity slurry to achieve filament-level infiltration and encapsulation of fibers by the resin, effectively reducing porosity and strengthening interfacial bonding. The entire production line is equipped with online concentration detectors, tension adjustment systems, and thickness feedback control devices to ensure precise control of fiber content and consistent batch quality of the tape.
Part.03 Performance Advantages: Multi-Dimensional Comprehensive Competitiveness
PEEKFRTP®BF-UD Unidirectional Prepreg combines the dual performance advantages of continuous basalt fiber and PEEK resin, forming a full-dimensional competitiveness covering mechanical, thermal, chemical, and processing characteristics:
High Temperature Resistance: Maintains structural stability and mechanical properties over long periods in high-temperature environments, meeting the stringent requirements of hot zone components.
Chemical Corrosion Resistance: Exhibits strong resistance to acids, alkalis, salt spray, and organic solvents, suitable for harsh corrosive environments such as chemical and marine industries.
Electrical Insulation Performance: High volume resistivity and low dielectric loss, meeting the application needs of wave-transparent structures and electrical insulating components.
Fatigue Resistance and Impact Toughness: Strong interlayer bonding and high damage tolerance, capable of withstanding dynamic loads and cyclic stresses without delamination failure.
Thermoplastic Processing Characteristics: Inherits the weldability, thermoformability, and recyclability of thermoplastic materials, facilitating subsequent processing and recycling, with balanced overall performance and wide environmental adaptability.

PEEKFRTP®BF-UD Unidirectional Prepreg Technical Parameter Property Sheet
Part.04 Application Breakthrough: The Black Gold Code for Filament Winding
PEEKFRTP®BF-UD Unidirectional Prepreg demonstrates irreplaceable competitive advantages in the field of filament winding. Its core value lies in a key breakthrough in laser-assisted in-situ consolidation technology—the opening of this technical pathway fundamentally solves the process matching problem between insulating fibers and high-speed laser winding.
Winding Process Adaptability: The unidirectional tape has uniform thickness and excellent flexibility, enabling precise tension control and interlayer layup on CNC winding machines, suitable for efficient manufacturing of equal-thickness or variable-thickness axisymmetric components (e.g., gas cylinders, pipes, shells).
Laser-Assisted In-Situ Consolidation: PEEKFRTP®BF-UD Unidirectional Prepreg works in conjunction with a laser heating system to achieve integrated winding-melting-consolidation forming. Basalt fiber has good absorption of near-infrared lasers (808 nm, 1064 nm). Laser energy is efficiently absorbed by the fiber surface and conducted to the PEEK matrix, driving rapid melting and interlayer welding. In contrast, natural glass fiber, due to its high light transmittance and low laser absorption, is difficult to effectively consolidate in situ. Junhua HPP has successfully broken the technical bottleneck of “insulation equals low efficiency,” achieving process matching between insulating fibers and high-speed laser winding.
Against the backdrop of the rapid adoption of advanced manufacturing processes such as filament winding and automated fiber placement, PEEKFRTP®BF-UD Unidirectional Prepreg, with its unique advantages in high-temperature resistance, corrosion resistance, laser weldability, and cost, is becoming a new alternative to traditional metals and thermoset composites.
From the “aristocratic route” of carbon fiber to the “affordable route” of basalt fiber, the company has been deeply engaged in the field of specialty composite materials for many years, always driven by high-end R&D demands. This PEEKFRTP®BF-UD Unidirectional Prepreg is a mature product designed to meet the import substitution needs of specialty materials in high-end domestic sectors. It can be customized with different widths and fiber areal densities according to downstream customer requirements, helping high-end manufacturing in various fields achieve performance upgrades.
