• Increase of the thermal stability of glass fiber fabrics and the products produced from by a sol-gel surface treatment

Methods

• Sol-gel synthesis of coating materials (SiO₂/ZrO₂). Coating of the glass fiber fabrics by dip or spray techniques, followed by thermal curing (100 °C, 30 minutes)

Results

• Improvement of the temperature resistance by more than 200 °C in comparison to uncoated or commonly used aluminum phosphate coated glass fiber fabrics (also under tensile or shear load)

• Inexpensive high-temperature insulation materials
• Asbestos substitution

Benefits

• High flexibility of the coated fabrics and excellent adhesion of the coating under shear stress
• Improvement of handling conditions for mechanical treatment (e. g. cutting)
• Recyclable
