Fiberkuk

Fiberkuk is a class of high-performance synthetic fibers designed for strength and lightness in textiles and composite materials. The term appears in materials science literature and refers to fibers produced by melt-spinning thermoplastic polymers with processing steps that enhance molecular orientation and compatibility with resin matrices.

They are typically produced by melt-spinning a thermoplastic polymer or polymer blend, followed by drawing to orient the polymer chains and heat-setting to lock in structure. Additives such as stabilizers or flame retardants may be included, and some formulations incorporate surface modifiers to improve bonding with composite matrices.

Fiberkuk fibers generally exhibit high tensile strength and stiffness, good abrasion resistance, and low moisture uptake compared with natural fibers. They can be engineered for enhanced thermal stability and chemical resistance through polymer choice and processing.

Common applications include reinforcement in lightweight aerospace and automotive composites, high-performance textiles, filtration membranes, and sporting goods where strength-to-weight is important.

Environmental and lifecycle considerations are similar to other high-performance fibers. Production can be energy-intensive, and end-of-life options range from mechanical and chemical recycling to energy recovery, depending on polymer composition. Ongoing research aims to improve recyclability and reduce environmental footprint while maintaining mechanical performance.
