AGY, the sole U.S. manufacturer of premier high-performance glass-fiber reinforcements, and A+ Composites, a German innovator in unidirectional (UD) thermoplastic tapes, will showcase the new class of ultra-lightweight, high-performance thermoplastic UD tapes introduced earlier this summer at CAMX 2025. The collaboration features AGY’s newly developed lightweight single-end S2 Glass® roving integrated into UD tapes with LM-PAEK and PEI resin systems. This unique, cutting-edge solution is in the running for a CAMX Innovation Award.

Technical Highlights

Fiber: AGY S2 Glass® roving known for superior specific strength and stiffness

Resin Systems: LM-PAEK (Low Melt Polyaryletherketone) and PEI (Polyetherimide), offering high thermal stability and chemical resistance

Tape Format: Thicknesses from 50 µm to 6 mm; fiber volume fraction 35%–65%

Mechanical Properties: Tensile modulus up to 56 GPa and tensile strength exceeding 1,700 MPa (dependent on fiber/resin and process)

Key Benefits

High Specific Performance: Continuous fiber alignment maximizes load transfer in the UD direction for greater strength and stiffness

Heat & Dielectric Performance: AGY S2 Glass® with LM-PAEK/PEI delivers excellent heat resistance and dielectric properties suitable for RF/radar-transparent structures

Recyclability & Reprocessability: Thermoplastic matrix enables reheating, reshaping, and repair to support sustainable manufacturing

Fast, Efficient Processing: No cure cycle—heat, form, cool. Compatible with automated out-of-autoclave methods including ATL, AFP, and press/stamp forming
