Abstract
A process for preparing a composite part, the process comprising: recovering unsaturated resin prepreg scrap; combining the recovered unsaturated resin prepreg scrap with a second resinous thermosetting component; and co-molding the prepreg scrap and resinous thermosetting component together under a pressure of 25 to 4000 psi and at a temperature of 100-400° F.
Claims12
A composite part prepared by a process, the process comprising:
- (i) recovering unsaturated resin prepreg scrap;
- (ii) combining the recovered unsaturated resin prepreg scrap with a second resinous thermosetting component comprising an unsaturated resin;
- and
- (iii) co-molding the prepreg scrap and resinous thermosetting component together under a pressure of 25 to 4000 psi and at a temperature of 100-400° F., wherein chemical bonding occurs between the unsaturated resin prepreg scrap and the second resinous thermosetting component comprising an unsaturated resin, resulting in an increase in homogeneity and decrease in voids in the composite part compared to mechanical integration alone.
