Abstract:

Amorphous bonding appears to be a promising method of joining thermoplastic matrix advanced composites. The temperature to bond, lower than for fusion bonding, and the limited dimension of the melted zone, allow significant cost reduction and guarantee good mechanical characteristics. On the other hand a potential problem exists, due to lower resistance to aeronautical solvents and service fluids, because of the amorphous nature of the bonding layers. The basic resistance to environmental degradation of the resins used for bonding, and the chemical stability of their blends with the semicrystalline matrices of the adherends, have been investigated.
