Abstract
Apparatus for the manufacture of oriented chopped glass fiber mats from non-conductive fiber feed stock is disclosed. Apparatus includes means for increasing the conductance of the feed stock, electrically insulative transfer surface; means for establishing and maintaining a directional electric field to orient the chopped fibers, and a mat receiving surface to receive the oriented mat. The non-woven mat comprises a plurality of cut or chopped fibers having their longitudinal axes predominately disposed approximately parallel to a predetermined orientation axis lying in the plane of the mat. A preferred embodiment includes the incorporation of a glass fiber mat into a composite by applying a matrix resin to the mat in sufficient quantity to ensure the integrity of the composite. The process for manufacturing said non-woven oriented mats is also disclosed.
