Effect of resin-rich bond line thickness and fibre migration on the toughness of unidirectional Carbon/PEEK joints

It is a common practice in fusion bonding of thermoplastic composites to add a matrix layer between the two substrates to be joined. The aim is to ensure proper wetting of the two parts. The effect of this additional matrix layer on the mechanical performance was studied by mode I fracture toughness measurements. The additional matrix was...
