    Notes: A multiparameter corresponding-states correlation has been developed to describe fossil-fluid thermodynamic properties needed to design fluid-flow, heat-exchange, and other unit operations in coal-liquefaction plants. Three equation-of-state parameters, a molecular-size/separation parameter, a molecular-energy parameter, and a molecular-orientation parameter are used to characterize nonpolar and slightly polar aromatic hydrocarbons. A conformal-solution model is developed for predicting thermodynamic properties of coal-derived mixtures.

    Notes: A kinetic model has been developed for radical chain growth type of reactive polymer processing operations. This model incorporates considerations of the molecular diffusion that is described by a free volume theory and the basic reaction mechanism of the free-radical chain polymerization. Experimental results from the bulk styrene polymerization and a reaction of sheet molding compound (SMC) showed good agreement with the model.

    Measurement of structured microbial population dynamics by flow microfluorometry (1978)

    Notes: Commercial microbiological processes frequently contain dispersed microorganisms which are heterogeneous in their age, size, and composition. Relative protein and nucleic acid contents of individual bacteria in Bacillus subtilis submerged cultures have been measured experimentally using laser flow microfluorometry. Marginal and joint population composition density data and their complex patterns of evolution during batch growth provide an impetus and emerging basis for a new generation of potentially robust mathematical models of microbial systems.

    The resin-fiber interface in polyurethane and polyurethane-unsaturated polyester hybrid (1990)
    Brookfield, Conn. : Wiley-Blackwell

    Notes: A polyurethane (PU) is compared with the polyurethane-unsaturated polyester (PU-UPE) hybrid to examine the changes of the resin-fiber interphase in the presence of a sizing compatible component, UPE, in the matrix resin. The formation of resin-fiber interphase is critical in structural reaction injection molding (SRIM) and resin transfer molding (RTM) because resin solidification (i.e., gelation and vitrification) occurs in seconds (SRIM) or minutes (RTM). Kinetic (DSC, FTIR spectroscopy), mechanical (single fiber test, fracture surface analysis), and microscopic (birefringence, SEM) studies were used to analyze the interface. Kinetic results indicate poor chemical compatibility of the sizing with PU and increased chemical interactions of the sizing with the PU-UPE resin. Mechanical and microscopic analyses also point in favor of improved interphasial behavior with the PU-UPE resin.

    Analysis of resin injection molding in molds with preplaced fiber mats. I: Permeability and compressibility measurements (1991)
    Brookfield, Conn. : Wiley-Blackwell
    Polymer Composites 12 (1991), S. 20-29

    Notes: This work presents the characterization of fibrous reinforcement mats in resin injection molding. The fiber mat characterization involved determining the mat permeability and compressibility. Mold filling experiments were conducted using two or more different fiber types in the mat stack, which created transverse porosity, permeability, and compressibility variations. The effect of these 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.

    Notes: The primary goal of this study was to develop 2-D and 3-D computer simulation schemes for the mold filling processes of structural reaction injection molding (SRIM) and resin transfer molding (RTM) under isothermal conditions. The developed computer code was able to simulate the mold filling in molds with complicated geometry, Experiments were also carried out based on flow vitalizations. Experimental results were compared with the numerical simulations.

    Fiber mat deformation in liquid composite molding. I: Experimental analysis (1993)
    Brookfield, Conn. : Wiley-Blackwell

    Notes: 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.

    Performing analysis of thermoformable glass fiber mats - deformation modes and reinforcement characterization (1994)
    Brookfield, Conn. : Wiley-Blackwell

    Notes: This work is and anyalysis of the performing process of a thermoformable glass fiber mat. Important processing variables associated with the preforming operations were extracted from stamping experiments. From the study of deformation modes, we may conclude that the defects found in fiber mat preforming are closely related to these deformation modes. Stretching causes finer thinning and re-orientation. Bending results in mat springback and thickness reduction, while in-plane compression induces wrinkles through buckling. Each defect may be reduced by specific adjustments. These adjustments, however, tend to interact with each other, and make the preforming control a challenging task.
