Tougher and stronger carbon fibre reinforced composites have been prepared using inkjet printing to deposit discrete polymer droplets onto the composite precursor. The polymer system that has been inkjet printed is a dual material system, in which half of the deposited droplets contain PMMA and the other half contain PEG. The resultant uni-directional carbon fibre reinforced composite exhibits improved mechanical properties with a barely noticeable increase in weight. For the dual material PMMA & PEG system, mode I interlaminar fracture toughness is increased by 40%, with evidence that higher values are possible. Additionally, initial experiments indicate that a significant increase (~5%) in apparent interlaminar shear strength is also observed.
