  • analysis of polymeric composite interphase regions with thermal atomic force microscopy
    Journal of Applied Polymer Science, 2001
    Co-Authors: Matthew S. Tillman, Brian S. Hayes, James C. Seferis
    Abstract:

    Previous work on the characterization of interphase regions in thermoset- ting composite Systems has focused on the inference of an interphase layer from effects noticed through macroscale mechanical and thermal testing. With the development of atomic force microscopy and active thermal probes for this technique, it is now possible to examine material thermal properties on a much smaller scale. Variations in mi- croscale thermal properties of an aerospace-grade Thermosetting Resin System were evaluated for carbon and glass fiber reinforcement, using the modulated local thermal analysis mode of a TA Instruments 2990 TA. The variations observed clearly demon- strate the presence of a soft interphase layer in the glass material and underline the importance of fiber-matrix interactions during the formation of the interphase. © 2001 John Wiley & Sons, Inc.

  • Thermosetting Resin System based on novolak and bismaleimide for Resin transfer molding
    Journal of Applied Polymer Science, 2002
    Co-Authors: Yehai Yan, Xianming Shi, Jinge Liu, Tong Zhao
    Abstract:

    A Thermosetting Resin System for Resin-transfer molding based on novolak and bismaleimide (BMI) was developed. The novolak Resin was allylated and BMI was used as the curing agent, and allyl phenyl ether, as the diluent. The viscosity–temperature curve and the viscosity–time curve were used to characterize the processing property of the Resin System. The Resin System had a long pot life at the injection temperature. Based on the DSC data, a regime for the curing and postcuring cycles was established. The cured Resin showed outstanding heat resistance and good flexural properties. Composites based on the Resin System and woven glass fabric were fabricated using RTM technology. The composites showed very good flexural properties at room temperature and high retention rates at 200 and 300°C. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 83: 1651–1657, 2002
