Monitoring of hygrothermal ageing effects in an epoxy resin using FBG sensor: A methodological study

Joël Cugnoni, John Botsis, Dimitrios Karalekas

This study demonstrates the feasibility of using fibre Bragg grating (FBG) sensors to monitor the effects of hygrothermal ageing on the axial strains in a cylindrical epoxy specimen with a centrally located optical glass fibre. A 24 mm long FBG, inscribed ...

Interfacial intermetallic growth and strength of composite lead-free solder alloy through isothermal aging

Joël Cugnoni, John Botsis, Venkatesh Sivasubramaniam

The effects of particle reinforcement of Sn-4.0wt.%Ag-0.5wt.%Cu (SAC405) lead-free solder on interfacial intermetallic layer growth and strength of the ensuing joints through short-term isothermal aging (150 degrees C) were studied. Composite solders were ...
