    Notizen: Abstract The lacewing Chrysopa cognata, one of the principal predators of aphids in Korea, was tested for responses to the aphid sex pheromone components (4aS,7S,7aR)-nepetalactone and (1R,4aS,7S,7aR)-nepetalactol and the aphid alarm pheromone (E)-β-farnesene. Electroantennogram responses were obtained to the sex pheromone components but not to (E)-β-farnesene. The sex pheromone components were attractive in a Y-tube olfactometer assay and in field trials with water traps, but no attraction was observed to (E)-β-farnesene.

    Cold compaction molding and sintering of ultra high molecular weight polyethylene (1980)

    Notizen: Cold Compaction Molding and Sintering of Ultra High Molecular Weight Polyethylene (UHMWPE) has been examined as a function of particle size, sintering time and temperature, and cooling rate. Properties nearly equivalent to those obtained by compression molding can be obtained from samples with a fibrous particle morphology, sintered just above the melting point, with further improvement possible by control of particle size and addition of fine particles of normal molecular weight linear polyethylene. UHMWPE with a nodular particle morphology sintered poorly.

    Fiber mat deformation in liquid composite molding. II: Modeling (1993)

    Notizen: Mathematical models are proposed to simulate the flow induced fiber mat deformation during liquid composite molding. The fiber bed is treated as an elastic beam and the load acting on the bed causes its deformation. The lubrication approximation is used to simplify the resin flow equation in the fiber free region, while Darcy's law is used to calculate the pressure and velocity fields in the deformed fiber bed. The governing equations are solved using the control volume/finite element method. The numerical results show reasonable agreement with the experimental results from Part I.

    Fiber mat deformation in liquid composite molding. I: Experimental analysis (1993)
    Brookfield, Conn. : Wiley-Blackwell
    Polymer Composites 14 (1993), S. 144-150 
    Details

    Thema: Maschinenbau
    Notizen: When a resin in injected into the mold in liquid composite molding, the preplaced fiber mat may deform near the inlet gate because of the high momentum carried by the injected fluid. A fiber free region near the gate followed by the fiber mat deformation may emerge. This phenomenon is most likely to occur when the stacked fiber mats have low permeability and the resin has high viscosity. A set of mold filling experiments were carried out using an instrumented metal mold and a small transparent mold to investigate the fiber mat deformation during mold filling. Experimental results showed that the fiber mat deformation was limited to a small region near the gate and that deformation greatly reduced the molding pressure. A forced fiber mat deformation employing a modified gate design was proposed to facilitate mold filling in liquid composite molding.

    Analysis of resin injection molding in molds with preplaced fiber mats. II: Numerical simulation and experiments of mold filling (1991)
    Brookfield, Conn. : Wiley-Blackwell
    Polymer Composites 12 (1991), S. 30-38

    Thema: Maschinenbau
    Notizen: This work presents the results of numerical simulation and experimental visualization of the mold filling process in resin injection molding with preplaced fiber mats. The mold filling experiments were conducted with various mat stacks consisting of continuous random glass fiber mats and bidirectional stitched glass fiber mats. The use of two different mat types in the mat stack created porosity and permeability variations. The effect of these permeability variations was studied by taking flow pressure measurements and observing the progress of the flow front of a non-reactive fluid filling a clear acrylic mold that contained the reinforcement mat stack. Numerical simulation corresponding to each experiment was also carried out. The numerical results were compared to the experimental measurements.

    Analysis of cylindrical shells under patch loading (1986)

    Notizen: The object of this study is to predict the peak values of the stress resultants and couples in a relatively thick cylindrical shell under a concentrated local loading in order to guide the design of a large-scale reinforced concrete test specimen. Four finite element programs, SHORE-III, two versions of RONALD, and ANSYS, were employed here. The SHORE-III and RONALD analyses considered a complete cantilevered cylinder, while the ANSYS model treated a cylindrical panel free along the curved edge and constrained in various ways along the longitudinal edge. Comprehensive comparative results are provided for the linear elastic loading case, which indicate the magnitude and attenuation of concentrated loading effects on cylindrical shells and panels.
