<p>The present invention provides a method of forming unidirectional laminate prepreg, comprising the steps of: providing a support table; advancing a plurality of strands oriented generally parallel to each other along at least a portion of the table; positioning a removable carrier material between the strands and the table to support and move with the strands along at least a portion of the table; coating at least a portion of the strands with a resin matrix material to form a pre-cured prepreg; establishing a uniform thickness for the pre-cured prepreg; at least partially curing the matrix material of the pre-cured prepeg to form an at least partially cured prepreg; and accumulating the at least partially cured prepreg. In one nonlimiting embodiment of the invention, the strands comprise a plurality of glass fibers, the carrier material is plastic, the removing step includes the step of positioning an edge of a doctor blade in contact with an upper surface of the pre-cured prepreg to establish the thickness of the pre-cure prepreg, and the at least partially curing step includes the step of passing the pre-cured prepreg through at least one curing and drying oven.</p> |
