Dielectric strength of ion irradiated polyimide and epoxy/fiber composites
During long-term operation of the new FAIR facility, parts of the superconducting magnets will be exposed to high radiation levels, cryogenic temperatures, and dynamic mechanical loads (Lorentzian forces during pulsed operation). Depending on the position of the different components, the radiation due to beam losses consists of a cocktail of gammas, neutrons, protons, and heavier particles [1]....
متن کاملIncreased Flexural Modulus and Strength in SWNT / Epoxy Composites by a New Fabrication Method
A new method for preparing SWNT/epoxy nanocomposites has been developed which involves high shear mixing of the epoxy resin and SWNT and heat treating the mixture prior to introducing the hardener. The glass transition temperature of the epoxy resin is unaffected by the presence of nanotubes. An improvement of 17% in flexural modulus and 10% in flexural strength has been achieved at 0.05 wt% of...

متن کاملThe use of polyimide-modified aluminum nitride fillers in AlN@PI/Epoxy composites with enhanced thermal conductivity for electronic encapsulation
Polymer modified fillers in composites has attracted the attention of numerous researchers. These fillers are composed of core-shell structures that exhibit enhanced physical and chemical properties that are associated with shell surface control and encapsulated core materials. In this study, we have described an apt method to prepare polyimide (PI)-modified aluminum nitride (AlN) fillers, AlN@...
