DH Sutherland (Beaverton, Ore., U.S.) is introducing technologies for chemical application and the manufacture of protective armor.
T-Link is a novel, dry prepreg system consisting of woven para-aramid fibers and a thermoplastic epoxy matrix. T-Link is said to enable armor manufacturers to improve scale and co-processability with other ballistic materials such as UHMW-PE.
According to the company, DH Sutherland and its partners developed T-Link to fill a need for dry prepreg reinforcement that is drapable, does not require refrigeration or special handling and that can be quickly consolidated into a composite structure. In the resultant T-Link dry prepreg system, DH Sutherland says, the coating is applied directly to a para-aramid tow. When delivered in a fiber, the weaving capability and size offerings are broad and determined by the weaver’s creel width. The technology is said to be ideal for armor manufacturers producing ballistic armor for applications in land vehicles, helicopters, maritime and personal protection applications.

In the field of chemical application, KleanVak technology fo
r mold preparation of composite parts andsolvent cleaning. The machine is said to significantly increase the speed of application, while simultaneously removing harmful volatile organic compounds (VOC) from the working environment.
KleanVak machine applies a thin layer of solvent onto the surface of the tool or part to be cleaned, while simultaneously vacuuming and safely containing any VOCs. The VOCs are then sent through an activated charcoal filter before the air is recycled. KleanVak is also said to
time by up to 80%,. In addition, KleanVak is said to enhance worker safety through both the capturing and filtering of VOCs as well as by enabling safe distancing between workers.
Thermoplastic tapes are not new to composites, but they soon will join the primary aerostructures material palette and could be their future.
Capable of volume production, thermoplastic composites will gain new market share in the aerospace industry.
Yes, advanced forms are in development, but has the technology progressed enough to make the business case?
