Methods of Forming FRP Composites

Fibres appropriate for civil engineering applications are available in three major formats continuous or chopped strands, woven or unwoven fabrics (sheets) and pre-impregnated forms. Commercially available fibres are produced in the form of spooled strands. 

They are later processed into other formats in secondary operations. The size of the fibre tow bundle can range from 1000 filaments (IK) to more than 200K. Generally, commercial-grade fibres appropriate for civil engineering applications have 48K or larger filament counts.
