Abstract: Described herein are polyamide foam particles including a polymer mixture including: (A) from 25 to 95 wt.-% of at least one polyamide, which is different from a copolyamide (B); and (B) from 5 to 75 wt.-% of at least one copolyamide prepared by polymerizing the following components: (B1) from 15 to 84 wt.-% of at least one lactam; and (B2) from 16 to 85 wt.-% of monomer mixture (M) including; (M1) at least one C32-C40 dimer acid; and (M2) at least one C4-C12 diamine; where the sum of the components (B1) and (B2) are 100 wt.-%. Also described herein is a process for preparing such polyamide foam particles and polyamide particle foam moldings obtainable by steam-chest molding.

Abstract: The invention relates to a process for the production of multishell composite-material components, comprising the following steps: a) insertion of at least one first component (1) into an injection mold and optionally subjecting the first component (1) to a forming process, b) injection of at least one fixing element (4) onto at least one side (5) of the first component (1), c) insertion of at least one second component (2) into the injection mold and optionally subjecting the second component (2) to a forming process, d) bonding of the first component (1) to the second component (2) by way of the side (5) which has the fixing element (4), where a matrix material (6) is injected through the second component (2) onto and/or into the fixing element (4).
