A+ Composites launches customizable LM-PAEK towpreg tapes with thin-ply option from 85 µm

A+ Composites, a materials supplier based in France, has introduced a new line of customizable LM-PAEK (low-melt polyaryletherketone) towpreg tapes available in carbon and glass fiber formats. The tapes can be produced to customer-specified sizes and include a thin-ply option starting at 85 µm, targeting improved fiber-matrix adhesion, high temperature and chemical resistance, and batch-to-batch reproducibility. The product is aimed at applications in aerospace, pressure vessels, and advanced industrial tooling where consistent thermoplastic prepreg quality is critical for automated layup processes like AFP and ATL.

This launch sits within the broader trend of PAEK-based thermoplastic composites gaining traction in serial production, particularly in aerospace and hydrogen storage. The LM-PAEK variant offers a lower processing temperature than standard PEEK or PEKK, reducing energy costs and enabling faster cycle times in consolidation and welding steps. A+ Composites is positioning itself against established players like Toray, Solvay, and Victrex, but with a focus on customization and smaller minimum order quantities — a gap in the market for mid-volume producers who need tailored towpreg widths and fiber architectures without committing to large-scale prepreg runs. The thin-ply capability at 85 µm also addresses a specific need in lightweight structural applications where ply-level optimization can reduce weight without sacrificing mechanical performance.

For buyers evaluating thermoplastic towpreg suppliers, the key differentiator here is not a breakthrough in material chemistry but in manufacturing flexibility. A+ Composites must now demonstrate that its customization promise holds at production scale — consistent quality across variable widths and fiber types, with reliable delivery lead times. Users in aerospace qualification programs should request full mechanical and thermal data sheets for the LM-PAEK system, particularly for long-term creep and fatigue behavior, before substituting established PEEK prepregs in certified parts.
