    Development of ‘optomechanical composites’, based on glass matrices reinforced with continuous oxide fibre bundles (Nextel™) or filaments (sapphire) is described. The fibres were arranged unidirectionally between soda-lime silicate or borosilicate glass slides, and heat-treated to achieve densification by viscous flow of the glass matrix between the fibres. Small decreases in light transmittance (up to approximately 20%) upon introduction of fibres was indicated. Fibre pull-out and crack deflection were identified at fibre/matrix interfaces, and a crack bridging effect was observed, with fibres holding the glass pieces together, thus preventing catastrophic failure. A relatively low fibre/matrix interfacial sliding resistance was measured by the fibre push-in test, although flexural strength measurements indicated the need to improve interfacial bonding.
