oberflaechenbehandlung von kohlenstoffasern und mechanische eigenschaften von laminaten. $left bracket$ surface treatment of carbon fibers and mechanical properties of laminates $right bracket$

in composites carbon fibers are used as reinforcing fibers with thermosetting and thermoplastic resins as matrices. these carbon fibers differ greatly in their microstructure and thus in their properties. to achieve adequate composite properties, special carbon fiber surface treatment methods are necessary. this paper describes a systemat..

overcoming startup problems at a new co-composting facility

the most difficult obstacle in starting operations at a new co-composting facility is initiating the new equipment with garbage and sewage sludge. once the millions of dollars worth of equipment have been properly christened, startup problems must be identified, prioritized, evaluated and resolved. one of the most important considerations..

carbon/graphite fiber reinforced poly(methyl methacrylate): properties under dry and wet conditions

the flexural properties of poly(methyl methacrylate) (pmma) reinforced with carbon/graphite (c/g) fibers with three different surface treatments were investigated by transverse bend testing after dry and wet storage. the coating agents of commercial unidirectional and braided c/g fibers as well as impurities on c/g fibers for medical uses..

influence of test frequency on the fatigue resistance of a ni-base eutectic composite

the high cycle fatigue life of aged nitac 14b at 825 $degree$ c in vacuum is strongly dependent upon frequency and at high frequencies, surface finish. crack initiation controls fatigue life at all frequencies, although the mechanism changes with frequency fiber cracking is especially prominent at low frequencies, as is dislocation penetr..

bonding of carbon fibres to epoxy resins as affected by the manufacturing and surface treatment processes

the differences in the bonding to epoxy resins, as measured by the interlaminar shear strength (ilss), of three nominally similar carbon fibers were related to differences in the manufacturing and surface treatment operations. two of the fibers (denoted a and c) were determined to have emerged from the manufacturing process essentially id..

membrane bioreactors: engineering aspects

membrane bioreactors have in-situ separation capability lacking in other types of immobilized cell reactors. this makes them very useful for certain systems. enzyme reactions utilizing cofactors and hydrolysis of macromolecules are advantageous in membrane reactors anaerobic cell culture may be efficiently carried out in membrane cell rec..
