Thermoplastic Unidirectional (UD) Tape: Materials, Processing Science, and Structural Implications for Continuous Fiber Composites

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com]Published : January 05 , 2026 Abstract Thermoplastic unidirectional (UD) tape has emerged as a critical intermediate material for next-generation continuous fiber reinforced composite structures. By combining aligned continuous fibers with melt-processable thermoplastic matrices, UD tapes enable rapid manufacturing cycles, weldable joining strategies, and improved […]

Crystallinity in PEKK and CF/PEKK Composites: Structure, Kinetics, and Processing Implications

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com]Published : December 09 , 2025 AbstractPoly(etherketoneketone) (PEKK) has emerged as a key matrix for high-performance thermoplastic composites, particularly in aerospace structures produced by automated tape placement, press moulding and welding. In contrast to poly(etheretherketone) (PEEK), PEKK offers tunable crystallisation behaviour through variation of the
