Abstract: The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

Abstract: ABTRACT
The present invention relates to a liquid, thermoplastic acrylic gel cap composition that can impart UV resistance, higher impact, and aesthetic effects to a composite material. Additionally, the post processing of the material when combined with a thermoplastic composite can allow for thermoformability, weldability and recyclability, unlike seen with traditional thermoset based gel coats.-

Abstract: The invention relates to a thermoplastic composition used for forming articles having both high gloss and excellent resistance to mar, scratch and/or abrasion. The composition contains very high levels of nano-sized inorganic additives, such as alumina, silica and titanium dioxide. Acrylic polymer compositions, such as Arkema's PLEXIGLAS® resins, with 5 to 25 weight percent of sized fumed silica are a preferred embodiment of the invention, especially when combined with a dye or pigment.
