formation of a very low-reflectance surface by electrostatic flocking
the implantation of carbon pile perpendicular to the substrate, thereby making it possible to form a surface having a very low reflectance owing to the so called light trap effect, where light beams incident of the surface are reflected and attenuated among the fibers no matter at which angle the light beam may incident, are considered. h..
waste minimization assessment for a manufacturer of commercial ice machines and ice storage bins. environmental research brief
waste minimization assessment centers (wmacs) were established at selected universities and procedures were adapted from the epa waste minimization opportunity assessment manual (epa/625/7-88/003, july 1988). the wmac team at colorado state university performed an assessment at a plant that manufactures commercial ice machines and ice sto..
intelligent processing equipment projects at dla
the defense logistics agency is successfully incorporating intelligent processing equipment (ipe) into each of its manufacturing technology thrust areas. several ipe applications are addressed in the manufacturing of two 'soldier support' items: combat rations and military apparel. in combat rations, in-line sensors for food processing ar..
waste minimization activities in the materials fabrication division at lawrence livermore national laboratory
the mission of the materials fabrication division (mfd) is to provide fabrication services and technology in support of all programs at lawrence livermore national laboratory (llnl). mfd involvement is called for when fabrication activity requires levels of expertise, technology, equipment, process development, hazardous processes, securi..
visual inspection system for evaluating the interior surface finish of valve flanges on hazardous material storage containers
hazardous material storage containers are used at the oak ridge y-12 plant for safely storing and/or transporting hazardous material products. figure 1 is a picture of the complete hazardous material storage container system. because of the adverse consequences associated with one of these containers leaking or releasing some or all of it..
interface fibre de verre/matrice polyepoxy: introduction d'une interphase a proprietes controllees (fiber glass/polyepoxy matrix interface: introducing an interphase of controlled properties) ph.d. thesis
the interface between a polyepoxy matrix and e glass fibers submitted to various surface treatments is studied by means of two adhesion tests. a pull-out test and a microfilament fragmentation test are carried out. the glass fibers are used untreated or simply washed in a solvent. the behavior of glass fibers wrapped in an interphase of k..
industry sector analysis canada: women's apparel. export trade information
the analysis covers women's/girls' apparel. it does not include swimwear, lingerie, foundation garments, or sleepwear. the canadian market for women's apparel grew from us$4,398 million in 1989 to us$4,707 million in 1990 and an estimated us$4,458 million in 1991 indications are that the estimated annual average real growth during the nex..
influence du greffage electrochimique de fonctions aminees en surface des fibres de carbone sur les proprietes mecaniques d'un composite carbone-epoxy (influence of electrochemical grafting of carbon fiber surface amine functions on the mechanical propert
a pilot cell for continuous treating of carbon fibers which allows an important surface nitrogen level to be obtained on fibers already treated commercially (oxidizing treatment) and oiled is presented micromechanical and mechanical tests were carried out on the courtaulds xau-hs2 (high resistance)-epoxy narmco 5208 fiber system the resul..
model system studies on photosensitization in light scattering media. reprint: model system studies on photosensitization in light scattering media
biological photosensitization is being investigated in tissue models consisting of a sensitizing dye, a biological target, and light scattering particles. results are reported for a dihematoporphyrin ether-subtilisin carlsberg-polystyrene microsphere system in which the rate of photodynamic enzyme inactivation was measured at different wa..
quantitative interphase study of composite materials. interphase engineering: a scientific way of tailoring the mechanophysical properties of composite materials. final rept. 1 jul 88-31 dec 91
the projects covering july, 1988 - december, 1991 were concerned with the application of a new technique, nmr imaging, to interface studies; preparation of composites with special innerlayers; and systematic surface treatment of carbon fibers and characterization of surfaces. we have studied all proposed areas and obtained several major b..
