“…They are therefore candidates for production of tough glass matrix composites (GMC) [7]. Alumina fibres have been investigated previously as reinforcement in silicate matrix composites, and control of the interface was shown to be critical to improving fracture toughness [2,[6][7][8][9][10][11][12][13][14][15][16]. Dericioglu and Kagawa have demonstrated enhanced fracture toughness on incorporation of a ZrO 2 interface in a glass matrix/alumina fibre composite, due to the absence of strong chemical bonding between the ZrO 2 layer and the alumina fibres.…”

“…However, no enhancement of toughness was observed[65]. In addition, the SnO 2 coating deposited on Al 2 O 3 -ZrO 2 (PRD-166) and sapphire fibres was seen to facilitate fibre pull-out, especially on the smoother sapphire fibres, due to the formation of a weak interfacial bond[67].The mechanical property results of PRD-166 fibre-reinforced borosilicate glass composites and Nextel TM 480 fibre-reinforced borosilicate glass composites have confirmed that the higher the fibre content, the higher the GMC Young's modulus[68]. It also has been found that the composites' stiffness and elastic properties in both systems did not seem affected by the presence of the SnO 2 interfaces.…”

“…It also has been found that the composites' stiffness and elastic properties in both systems did not seem affected by the presence of the SnO 2 interfaces. Furthermore, due to a higher level of fibre misorientation of coated fibres compared to uncoated fibres, incorporating SnO 2 -fibre coatings into the composites did not improve their shear modulus[68]. However, introducing Nextel TM 440 alumina fibre into borosilicate glass could improve the composite's flexural strength and fracture toughness[31].…”

Glass matrix composites based on NextelTM fibre reinforced borosilicate glass were fabricated. Unidirectional fibres were arranged in two directions with a periodic interspacing sandwiched between two glass slides. XRD analysis and SEM observations proved that the selected process parameters were effective in densifying the composites without significant transparency losses. A geometry based equation was derived to evaluate the expected light transmittance of the composites. ZrO2 coating on Nextel™ fibres, developed by a sol-gel method, was investigated in order to provide a weak bonding at the fibre/matrix interface to promote fibre pull-out during fracture. A developed hybrid sol-gel coating method was employed to form a smooth and crack free coating surface on the Nextel™ fibre bundles. The present composites show potential for applications in architecture and special machinery requiring strong transparent windows.

Glass and glass–ceramic matrix composites represent a very particular type of composite materials. As in most ceramic matrix composites, the reinforcements are mainly intended to increase the resistance to crack propagation, that is, the most significant weakness of the matrices, due to several toughening mechanisms. Unlike polycrystalline ceramic matrices, however, glasses offer the distinctive feature of viscous flow, being readily deformed and flowed in their low viscosity state, with the possibility of incorporating secondary phases at moderately high temperatures. Fibrous reinforcements (mainly C and SiC fibers) are at the basis of materials with impressive properties, for example, strength above 1 GPa, fracture toughness up to 35 MPa m 0.5 , almost zero thermal expansion, and service temperature up to 1500°C, but still facing high costs, although known for many years. Recent applications, such as that of “optomechanical materials,” that is, transparent materials with improved crack resistance, may stimulate research investments and production. As an alternative, dispersion‐reinforced composites, first seen as lower value category, owing to the limited improvements in fracture toughness, are currently the candidates for extensive industrial production, since the low cost treatments applied may be combined with complex combinations of different functionalities.
