“…and Iba and Kagawa et al ., where glass fiber in chopped and continuous forms have been used to reinforce borosilicate glass. For silicate matrix composites, the use of unidirectional or randomly orientated chopped alkali‐resistant glass and ceramic fibers for different soda lime glass matrices has also been reported in literature. The polymeric, metallic, and natural fibers such as polypropylene (PP), polyamide, steel, and cellulosic fibers can also be used to improve the impact properties of such brittle matrices.…”

This work reports the effect of an alkaline environment and ultraviolet (UV) radiation on the physical, thermal, and tensile properties of different fibers selected as potential reinforcing elements to enhance the impact properties of brittle glass/silicate composites. The fibers, which included regenerated cellulosic (viscose and rayon), synthetic (ultrahigh molecular weight polyethylene, polypropylene, polyamide, acrylic), glass, ceramic, and steel, were aged in different alkaline solutions with pH ranging from 11.1 to 13.6 at 70°C for different periods of time and exposed to UV radiation for 330 h. The physical and thermal properties of aged fibers were studied using tensile testing, scanning electron microscopy, and simultaneous differential and thermogravimetric analysis. Results showed that the regenerated cellulosic fibers, acrylic, E‐glass, and A‐glass fibers could not withstand the highly alkaline environment. Overall, ultrahigh molecular weight polyethylene, UV‐stable polypropylene, polyamide 6.6, AR‐glass, ceramic (alumino borosilicate), and steel fibers performed very well under all conditions, indicating that they have the potential to be used as reinforcing elements in glass/silicate composites.

“…The main objective of introducing high modulus and strong fibres into brittle ceramic matrices is their contribution to increased toughness [25]. To achieve this goal, control of the fibre/matrix interface represents a critical step in the development of CMCs and GMCs, because the interface occupies an extremely large area in the composites and is the key to determining their mechanical properties.…”

“…Continuously adding the oxalic acid solution to a solution of zirconyl chloride results in a decrease of the pH of the sol, meanwhile the viscosity of the sol increases initially slightly until a sudden increase is observed. This leads to the formation of a thick and white gel, which is used to obtain a clear sol by applying further agitation [25]. Baklanova et al [57] investigated the dip-coating of Nicalon TM fibres by using a zirconyl oxychloride sol-gel process.…”

“…Composite systems made of borosilicate glass/sapphire fibre and borosilicate glass/Nextel TM fibre were investigated. To induce toughening mechanisms in the composite, coating of the fibres with an oxide (ZrO 2 ) layer was the chosen approach to optimize the fibre/matrix interface, which should lead to fibre pull-out and debonding mechanisms during fracture of the composite [25,26]. In addition, composite transparency was investigated by employing the "optical window" concept which enables light to be transmitted through the area of the composites free of fibres.…”

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.
