Cascell® RS is specially developed for use as a structural core in connection with vacuum infusion processes, such as VARI and RTM. It is applied in components of aviation, aerospace, sports equipment with resin injection process to reduce the weight. Its mechanical and thermomechanical properties are similar to those of Cascell® WH. Its cell size, which is smaller, achieves an optimal compromise between low resin absorption-about 30% less than for Cascell® WH-and satisfactory bonding of the facings to the core.
Processing and production
Cascell® RS is especially suitable for vacuum infusion and RTM processes due to its optimized cell structure, where it can be used at temperature up to 180°C with pressure up to 0.7 MPa after heat treatment.
Thermoforming and shaping
Cascell® RS 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® RS Machining Department.
