Abstract
A method of pultrusion is provided that includes the steps of saturating a bundle of fibers in a curable resin, pulling the saturated fibers (also known as "prepreg") into a flexible mold, manipulating the mold (with the saturated fibers therein) into a given shape or form, allowing the saturated fibers to cure or harden, and then removing the flexible mold by mechanical or chemical means. This novel method permits one to mold prepreg into any given shape prior to hardening, not limited by the shape of a given mold or die.
Claims16
A method of molding reinforced synthetic resinous bodies comprising the steps of
- (a) supplying a plurality of fibers;
- (b) saturating said fibers with a resin;
- (c) supplying a flexible mold to receive said saturated fibers;
- (d) introducing said saturated fibers into said flexible mold;
- (e) manipulating said flexible mold into a desired shape or form;
- (f) allowing said resin to cure;
- and
- (g) removing said flexible mold.
A method of molding reinforced synthetic resinous bodies comprising the steps of
- (a) providing a plurality of fibers;
- (b) providing a hollow, elongated, flexible mold;
- (c) attaching said fibers to a hook capable of pulling said fibers into said flexible mold;
- (d) providing a heat hardenable resin;
- (e) saturating said fibers with said resin to thereby form resin saturated fibers;
- (f) pulling said resin saturated fibers into said flexible mold;
- (g) manipulating said flexible mold into a desired shape;
- (h) curing said resin to hardness;
- and
- (i) removing said flexible mold from said cured resin saturated fibers.
