Development and Characterization of Transparent Glass Matrix Composites


Article Preview

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.
