“…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.…”

“…BN coatings can improve the fibre/matrix interface bonding leading to fibre pull-out and enhanced flexural strength and fracture toughness of the composites[59]. Thus, BN layers have been used to coat Nextel TM 440 fibres and SiC fibres via CVD/CVI deposition[23,31,[93][94][95].…”

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.

“…The best results in terms of increasing the fracture tolerance and imparting a pseudo-ductile fracture behaviour to brittle matrices is achieved with continuous fibre reinforcement, including unidirectional and cross-ply fibre alignment, and 2-and 3-dimensional fibre architectures. The vast majority of work concerned with fibre reinforcement of glasses and glassceramics has focused on using ceramic fibres, such as carbon [2,3], SiC yarn (type Nicalon) [3][4][5][6], SiC monofilament [7], alumina/zirconia (Type PRD-166) [8], polycrystalline alumina [9], single crystal alumina (Saphikon) [8] and mullite (Nextel 480) [10]. The reinforcement of glass matrices by continuous ductile elements has been much less investigated, despite the advantages they may have over their ceramic counterparts.…”

Abstract. A processing route has been developed for the fabrication of metallic fibre mat reinforced glass matrix composites. For the model experiments reported here, a commercially available satin woven stainless steel 316L fibre mat was used as the reinforcement and soda-lime glass as the matrix. The process involves two steps: (1) the infiltration of the intra-and inter-tows regions of the fibre mats with silica sol using electrophoretic deposition and (2) the fabrication of a composite by cold uniaxiat pressing and pressureless sintering of impregnated fibre mats sandwiched between layers of the matrix glass powder. The sintering took place in air at 670 ~ and composite materials of sufficient integrity could be obtained without damaging the fibres. The deposited silica remained amorphous at the processing temperature providing a porous interface between the glass matrix and the metallic reinforcement. Observation of fracture surfaces revealed that both fibre pull-out and fibre deformation occur, which should lead to a significant toughness enhancement. The presence of the interfacial silica layer, deposited using electrophoresis, is thought to be responsible for this behaviour.
