| abstract |
The present invention provides methods for treating continuous lengths of resin-impregnated sheets (11) so that they can be supplied in roll form, i.e., like a bolt of cloth, for subsequent processing or use. The methods feature the step of winding the continuous length (11) and a separation layer (12) of a material into a roll (10) with the layer separating successive wraps of the continous length of sheets, followed by a curing step if the resin is a thermosetting resin or by the application of heat and/or pressure otherwise. The continuous lengths optionally may comprise at least one sheet of film, too. The separation layer (12) of material remains separable from the continuous length (11) after treatment. Composite articles made from certain of these continuous lengths are ballistic resistant. |
