K counts filaments, not quality. Why 3K and 12K tow give different ply thickness, drape and throughput, and how to write a spec that fits.

A 2,200 m gas tieback put carbon fibre PA12 pipe into producing service. Four line items decide the order: liner, tape, end fitting, jacket.

Welding a thermoplastic composite is not welding plastic. The joint is won or lost in the resin-rich layer just beneath the surface.

Stiffness and strength answer different questions. Specify the wrong one and the part ends up too flexible or too brittle.

Order books for eVTOL aircraft are filling. The airframe is a stiffness and damage-tolerance problem, which changes what you specify.

Six Chinese carbon fibre producers sold more and earned less in Q3. The margin now sits in prepreg, and specification is the lever.

EU safeguard measures on glass fibre shift sourcing risk from price to quota: what buyers should fix in the next two quarters.

PFAS-free PPS compounds and what they change for wear parts: fibre choice, counterface wear, and the evidence a buyer should ask for.

Four late-October 2026 signals, from a US large-tow plant sale to PA6 resin increases, and what each one changes for a prepreg buyer.

Each heat cycle moves molecular weight and fibre length. What recycled content really means, and what to check before specifying regrind.
