Abstract
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.
