The Laser Interlaminar Reinforcement of Continuous Glass Fiber Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interlaminar crack initiation and propagation are a major mode of failure in laminate fiber reinforced composites. A laser reinforcement process is developed to bond layers of glass fabric prior to the vacuumassisted ...
Effects of Laser Radiation on the Wetting and Diffusion Characteristics of Kovar Alloy on Borosilicate Glass
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this study was to investigate the advantages of laser surface melting for improving wetting over the traditional approach. For comparison, kovar alloy was preoxidized in atmosphere at 700 °C for 10 min, and ...
Interlaminar Toughening of Fiber-Reinforced Polymers by Synergistic Modification of Resin and Fiber
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The synergistic effect of combining different modification methods was investigated in this study to improve the interlaminar toughness and delamination resistance of fiber reinforced polymers (FRP). Epoxy-compatible ...
Experimental and Numerical Investigation of Laser Forming of Closed-Cell Aluminum Foam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aluminum foams are generally very attractive because of their ability of combining different properties such as strength, light weight, thermal, and acoustic insulation. These materials, however, are typically brittle under ...
Effect of Deep Penetration of Interleaf on Delamination Resistance in GFRP
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of improving the delamination resistance and toughness of laminate fiber-reinforced composites especially for the drop-off structure is receiving considerable attention with the increasing need and application ...
Interlaminar Toughening of GFRP—Part I: Bonding Improvement Through Diffusion and Precipitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A low concentrated polystyrene (PS) additive to epoxy is used, since it is able to reduce the curing reaction rate but not at the cost of increasing viscosity and decreasing glass transition temperature of the curing epoxy. ...
Interlaminar Toughening of GFRP—Part II: Characterization and Numerical Simulation of Curing Kinetics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various methods of toughening the bonding between the interleaf and laminate glass fiber reinforced polymer (GFRP) have been developed due to the increasing applications in industries. A polystyrene (PS) additive modified ...
Liquid Handling Optimization in High-Throughput Biodosimetry Tool
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the need of high-speed and efficient biodosimetric assays for triage and therapy in the event of radiological or nuclear attack, a robotically based automated biodosimetry tool (RABiT) has been developed over the ...
