3A Composites Core Materials AIREX® R63.80 Damage Tolerant Foam
Categories: Other Engineering Material; Composite Core Material; Polymer; Thermoplastic

Material Notes: AIREX® R63 is a closed-cell, linear, thermoplastic polymer foam with extremely high damage tolerance. This formula combines high elongation and excellent bond strength. AIREX® R63 is cold formable to simple shapes and thermo-formable to complex three-dimensional curves, and is nonfriable. AIREX® R63 is a core material for dynamically loaded and shock absorbing sandwich structures.
