Composite materials

Composite materials or thermosets differ from thermoplastics with regard to their manufacturing process and machining properties.

In contrast to thermoplastics, thermosets cannot be remoulded using heat as assistance. These include various laminates and Bakelites such as EP-GC 203/G-11 (glass‑fibre‑reinforced woven laminate), EP GC 204/FR-4 (glass‑fibre‑reinforced epoxy laminate), UP GM203/GPO-3 (glass mat laminate based on polyester resin), PF and ETRONIT AS (cotton phenolic laminate and paper Bakelite), CEM-1, DURAPOL, RICOCEL and DUROSTONE (high-pressure laminates) and ALUCORE®, ALUCOBOND®PE, ALUCOBOND®plus, ALUCOBOND®A2, KAPA®tech and HYLITE® (aluminium sandwich boards).
