Corbett, Tim, Forrest, Mark, Law, Haydn and Fox, Bronwyn L. 2005, Melding : a new alternative to adhesive bonding, in SAMPE Europe 2005 : Proceedings of the 26th International SAMPE Europe Conference : Nanotechnology Assists Leadership and Success of the Composite Technology, SAMPE Europe Business Office, Nuglar, Switzerland, pp. 105-110.
Melding, a novel method for joining composites is examined in this paper. The method uses Quickstep ™ technology to retain partially cured areas of a composite laminate, enabling subsequent bonding operations. The effect of melding on the mechanical properties of the composite has been investigated. Flexural testing of HexPly 914 indicates consistent properties throughout a melded section. Flexural strength values of 1.36±O.03 GPa compared to 1.35±O.03 GPa for a standard laminate were recorded. In order to achieve sufficient bond strength, the portion of the composite to be joined must have a significant proportion of uncured matrix. The ability of Hexply 914 prepreg to retain sufficient bonding potential to form a strong joint was also investigated. HexPly 914 Lap Shear results indicated no significant variation in strength values between co-cured and melded joins, with a recorded strength value of 15.0±0. 7 MPa.
