Roving fabrics are fibreglass reinforcement materials where the glass is in the 0 and 90 degree directions (warp and weft) and therefore provides extra strength in these directions only. If there is an equal amount of glass incorporated in the warp and weft direction, it is called a balanced, or symmetrical fabric. If there is significantly more glass in 1 direction than in the other, it is called a uni-directional (UD), or unsymmetrical fabric.
Roving fabrics are designed as square fabrics as standard but are also available as twill weave fabrics (easier to drape) on request. These fabrics are available as standard from 300 g/m² to 800 g/m² (other weights are available on request). Compared to fine weave fabrics, roving fabrics have coarser yarns and are therefore cheaper.
Application
Roving fabrics are used for hand lay-up and injection techniques and are suitable for processing with polyester, vinyl ester and epoxy resins.
