Investigation of structure and properties of elemental carbon fibers with metal coating

Four types of metal coatings made of stainless steel, silver, titanium and copper were deposited on the surface of unidirectional carbon tape by the magnetron sputtering technology. The experimental evaluation results of strength of elemental carbon fibers with the metal coatings and strength of carbon-filled plastics based on them during the interlaminar displacement are presented. When producing the carbon-filled plastics an epoxy binder and the vacuum infusion technology were used. It has been found out that all the used metal coatings lead to an increase in strength of the carbon-filled plastics during the interlaminar displacement. The carbon tape with the stainless steel coating has the highest strength increase (by 50%). However, during long-term storage, the coating effectiveness of the metalized carbon tapes decreases.

In a radioactive material (RAM) packaging, the formation of eutectic at the Pu/SS (plutonium/stainless steel) interface is a serious concern and must be avoided to prevent of leakage of fissile material to the environment. The eutectic temperature for the Pu/SS is rather low (410°C) and could seriously impact the structural integrity of the containment vessel under accident conditions involving fire. The 9975 packaging is used for long term storage of Pu bearing materials in the DOE complex where the Pu comes in contact with the stainless steel containment vessel. Due to the serious consequences of the containment breach at the eutectic site, the Pu/SS interface temperature is kept well below the eutectic formation temperature of 410°C. This paper discusses the thermal models and the results for the extended fire conditions (1500°F for 86 minutes) that exist in a long term storage facility and concludes that the 9975 packaging Pu/SS interface temperature is well below the eutectic temperature.

Two types of metallic coatings (copper and zinc) were deposited on the surface of a unidirectional carbon tape by the method of magnetron sputtering. Results of experimental evaluation of strength of elementary carbon fibers with these metallic coatings and carbon-reinforced plastics based on them are presented. It has been found that the copper coating increases strength of the fibers and the carbon-reinforced plastics in case of the interlaminar displacement. The zinc coating decreases strength of the fibers and composites based on them. Parameters of the carbon fibers with metallic coatings after long-term storage of metallized carbon tapes are presented.

AbstractWe investigated the effect of the following on the sterile integrity of surgical packs: four wrapping materials (two-ply reusable, nonbarrier wovens, both new and previously used; disposable, barrier nonwovens; and polypropylene peel pouches), dustcovers, two storage locations, and storage times ranging from 2 to 50 weeks. Two hundred sixty-three packs containing stainless steel coupons were prepared, wrapped, sterilized, and stored. Half of the packs were dustcovered prior to storage. At monthly intervals for a year, packs of each type were opened in a laminar flow hood, and the coupons inoculated into trypticase soy broth. The coupon contamination probabilities were 0.019 for reusable, woven packs; 0.017 for disposable, nonwoven packs; and 0.016 for peel pouches. These differences were not significant. The probability of finding a contaminated coupon in any pack after 50 weeks was 0.018. No trend toward increased probability of contamination over time was observed for any of the pack types studied.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
