The strength imparted to the plastic by the glass fibre and the protection afforded to the glass fibre by the plastic, provide high profile properties.
- Low weight
- High elasticity
- Corrosion resistance
- Chemical resistance
- Good heat and sound insulation
The natural glass surface shows poor adhesion to polymers, particularly in the presence of moisture. For this reason the glass surface is adjusted organophilic by a size or finish treatment.
The essential components of the size or finish are silanes which effect
- Improvement of adhesion
- Transmission of glass fibre strength to the polymer
- Reduction of moisture sensitivity
- Mechanical protection of glass fibres
