  • Publication number: 20210395473
    Abstract: A matrix resin composition for fiber reinforced composite materials is described. The resin is thermosetting and achieves a glass transition temperature of at least 177° C. (Tg), obtained by curing under anaerobic conditions at room temperature. The matrix resin will streamline composite fabrication processes by eliminating the need for heating during the cure process. The implications of this development are significant in terms of the ease of use and elimination of procedural steps. While the resin system was developed specifically for vacuum bagging, it is expected to be viable for other composite fabrication methods including resin transfer molding (RTM) and vacuum-assisted resin transfer molding (VARTM). The resin system is viable for use with carbon fiber reinforcements to fabricate laminates at least 0.20 inches thick. The resulting laminates have low porosity and mechanical properties equivalent to those prepared with common epoxy matrix resins.

  • Patent number: 5942333
    Abstract: Metal surfaces treated with non-conductive metal oxides having enhanced non-conductive characteristics are disclosed. Durability and bond strength to polymer and metal surfaces is improved relative to non-treated metal surfaces. Methods of using metal surfaces with at least one non-conductive metal oxide coating in marine and under water applications are also described wherein cathodic delamination at the metal surface and a polymer is reduced, thus increasing the relative useful life of devices whose metal surfaces have been so treated. Methods for increasing bond strength and adhesiveness between metal surfaces wherein the metal surface is treated to include a metal oxide coat, such as a mixture of aluminum oxide and titanium oxide, are also described. The non-conductive metal oxide, or other non-conductive metal nitrides, carbides, borides or fluorides, coatings include at least about 20% to about 100% of the non-conductive metal oxide.

  • Patent number: 5670469
    Abstract: Improved compositions containing a visible coloring agent, such as a pigment or dye, together with a polymer or hydroxylated aliphate alcohol, and an active ingredient defined as a surfactant, a therapeutic agent or biocide, are disclosed. The detectable agent is readily visible under normal white light, and provides a technique for monitoring disturbed and undisturbed areas on a surface. Such is useful in the described methods for cleaning and/or decontaminating a surface, such as in the decontamination of equipment and clothing used during hazardous spill response. The compositions are adherent to a variety of different materials, including Teflon.RTM.. This makes the preparations particularly useful in the cleaning and decontamination of non-flat and curved surfaces, such as on protective garments.
