The SVI concept for composite interface design has the potential to be a versatile means of tailoring mechanical properties to match component application requirements. Instead of developing uniform interfaces to suit specific application requirements, a weak and a strong interface can be combined using the SVI concept to suit a range of requirements. Initial experimental work has produced means of fabricating random, helical and banded interface patterns, with banded patterns of different proportions. Preliminary mechanical tests demonstrating control of transverse tensile strength support an initial validation of the SVI concept of controlling interface mechanical properties by interface design.

The venue for future research in SVI's is wide. The effects of strong/weak area fractions, size scale and patterns will be explored in numerical models and mechanical tests. Fiber bridging and its effect on tensile fatigue will be evaluated for SVI's while continuing work on transverse cruciform tests.
