Romeo, Mich. – September 21, 2026 -- L&L Products has released Toughened T-Link®, a fully amorphous thermoplastic adhesive that delivered a 66% increase in compressive strength after impact under ASTM D7137 testing versus panels made with epoxy prepreg alone.
New adhesive targets ductility gaps in layered carbon-fiber composites
The technology extends L&L Products' existing T-Link® platform, adding enhanced impact resistance while retaining the dry-to-the-touch handling, room-temperature storage, and fast consolidation properties that define thermoplastic adhesive processing. Internal testing also showed a considerable increase in short beam shear performance under ASTM D2344 for panels incorporating Toughened T-Link® film between epoxy prepreg layers.
Material conforms to deep-drawn geometries, enabling thinner adhesive layers
Toughened T-Link® is engineered to conform to deep-drawn and irregularly shaped composite parts, a feature the company says opens the door to using thinner films and monofilaments. Don Paquet, senior scientist at L&L Products, said the platform lets manufacturers place adhesive only where structurally needed, reducing unnecessary weight and material use without sacrificing the processing advantages customers expect from thermoplastic systems.
Product ships in pellet, micropellet and film formats; yarn and filament in development
The adhesive is available now for purchase or sampling in pellet, micropellet, and film formats, with converted yarn and filament formats currently under development. L&L Products is positioning the material for applications involving high flexural loads, citing potential use in aerospace and sporting goods components.
Thermoplastic chemistry opens debonding and recycling pathways
Because Toughened T-Link® is thermoplastic rather than thermoset, the company notes it may support repairability, heat-based debonding, reprocessing, and recycling where compatible services and processes exist. The launch addresses what L&L Products describes as a long-standing industry need for greater ductility and damage tolerance in layered epoxy carbon-fiber composite structures.
