Cascell® WH foam core has been specifically designed for aerospace application, such as fairing and middle section of launch vehicle. It can also be used in back pressure frame of large civil plane due to its excellent mechanical properties. In the helicopters, Cascell® WH has been mainly used in main & tail rotor blades and fuselage panelsetc.
Processing and production
Cascell® WH can take curing temperature up to 130°C and pressure up to 0.3MPa. After heat treatment, Cascell® WH can even be cured at temperature of 180°C and at pressure of 0.7MPa.
Cascell® WH core makes it possible to produce sandwich components in a single step (co-curing), resulting in reduced overall production time.
Cascell® WH is highly suitable with autoclave technologies and vacuum infusion processes, including RTM and VARTM processes.
Thermoforming and shaping
Cascell® WH can be easily thermoformed or CNC machined to meet customers’ requirements, bringing tremendous manufacturing advantages.
High precision, pre-shaped and ready-to-use foam cores in complex or simple geometries can also be supplied by the Cascell® Machining Department.
