Abstract
The present invention relates to a composite component comprising an unfoamed polymer phase and a foamed phase, and to a process for producing the same.
Claims3
A process for producing a composite component, the process comprising:
- combining a portion of at least one lactam monomer with a catalyst to form a first monomer solution, and combining another portion of the at least one lactam monomer with an activator to form a second monomer solution;
- and mixing the first monomer solution and the second monomer solution to form a monomer mixture;
- contacting the monomer mixture with at least one foamed phase;
- and polymerizing the at least one lactam monomer to form an unfoamed polymer phase comprising a polyamide, wherein the polymerization occurs in the presence of the at least one foamed phase;
- where the unfoamed phase is produced by reactive injection molding (RIM).
