A system and method for thermoplastic composite welding comprising a cooling means and a heat source. The cooling means cools a heat-side laminate so as to create a thermal gradient in the heat-side laminate. The heat source heats the heat-side laminate after the...
Certain natural fibers have been attracting attention in order to mitigate the consumption of fossil fuels toward partly or totally replacing glass fibers in polymeric composites. The main organic sources for these fibers are the following plants: flax, hemp, sisal,...
De par leurs caractéristiques intrinsèques, les semi-conducteurs à grand gap, qu’ils soient à base de carbure de silicium (SiC) ou de nitrure de gallium (GaN), sont au cœur de toutes les attentions. Ils sont en effet capables de traiter des tensions nettement plus...
This study deals with the non-destructive test methods applied in the industry for SiC power metal-oxide-semiconductor field-effect transistors (MOSFETs). Scanning acoustic tomography (SAT) is used for testing SiC power MOSFETs, which are widely used in high-power...
