Screening method for the onset of bonding of molten polyamide resin layers to continuous fiber reinforced laminate sheets

Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...

Precision glass molding of high-resolution diffractive optical elements

Hans Peter Herzig, Toralf Scharf, Karin Prater

The demand of high resolution diffractive optical elements (DOE) is growing. Smaller critical dimensions allow higher deflection angles and can fulfill more demanding requirements, which can only be met by using electron-beam lithography. Replication techn ...
