Taffeta glass fabrics are woven 0°/ 90°.
They are dimensionally stable. Light weights (under 50g/m²) are used as a surface veil in the first coat, either directly on the part or behind a Gel-Coat.
They are generally more difficult to drape than twill fabrics and are therefore mainly intended for flat or less complex surfaces. These fabrics are used for hand lay-up, infusion and RTM applications.
25 and 48 gr/m² fabrics are regularly used in model making.
1.5 x grammage/m² (example: 1 m² fabric 162 gr/m² = 243 gr/m² resin per layer)
