Jaehyung Ju, Roger J. Morgan, E. Eugene Shin, May 2006

Interfacial failure between carbon-fiber/polyimide composites under high and low temperature exposures was characterized. Based on microscopic photos taken after exposures at -196°C and 250°C and thermo-elastic failure analysis, transverse microcrack formation of composites was investigated.

Improving the Properties and Economics of Fiber Reinforced Parts Using Glass Beads
Ufuk ?entürk, Bill Shaker, Chris Smith, Larry Royer, May 2006

Mechanical, thermal, and physical properties of five thermoplastic resins compounded using solid glass beads and fibers as additives was studied. Melt flow index is found as the most affected property as a function of bead size and bead-to-fiber ratio. Criticality of bead-to-fiber ratio in relation to product quality and processing is discussed. Material costs are also examined with respect to key property changes and a selection method is suggested to find an optimum.

Effect of heat-sealing temperature on fracture behavior of heat-sealed poly (lactic acid) (PLA) films was investigated according to the Essential Work of Fracture (EWF) technique. The EWF parameters obtained from heat-sealed PLA films that affected by heat-sealing temperature were investigated. The relationship between the EWF parameters and peel strength of heat-sealed PLA films was also discussed.

Novel Chitosan-Alginate Fibers for Wound Dressing Applications
Chijioke F. Iwu, May 2006

Alginate is a well known bioactive wound-dressing material. Similarly, Chitosan shows potential but has not been commercialized mainly due to high costs. Both materials can be engineered and produced as fibers to improve specific properties. Properties, FTIR and SEM analyses indicate a superior fiber for chitosan hydrolyzed and extruded with alginate. This process leads to synergy of the constituents in the new chitosan-alginate complex. The process is both precise and economical.

Soft, High-Temperature-Resistant Blends of Poly(Ethylene Alkyl Acrylate) Copolymers and Polypropylene
David J. Walsh, Mike M. Fill, May 2006

Blends of low melt index ethylene alkyl acrylate copolymers with polypropylene give a good combination of low hardness and high upper service temperature. The PP is the minor component, but due to the viscosity ratio of the polymers approaches a co-continuous phase. Of particular advantage are acrylate copolymers produced on a tubular reactor due to the compositional heterogeneity which gives improved compatibility with PP.

A.C. Ruddy, G.M. McNally, G.M. Walker, May 2006

In this study a range of thermoplastic polyurethanes were manufactured by various processing methods, temperatures and shear rates. The results indicate that these parameters had a significant effect on the morphological properties, especially at elevated temperatures and shear rates.

Strain Rate Dependent Failure of Plastic Materials
Jeffrey A. Jansen, May 2006

The response of plastic materials to mechanical stress is contingent on many variables. One very important characteristic is the rate at which the stress is applied, otherwise known as the strain rate. The effects of strain rate are reviewed and three case studies are used to illustrate failure resulting from rapid stress loading.
