DAMAGE TOLERANT FOAM
Description / A closed-cell, thermoplastic foam with an extremely high damage tolerance. It is cold formable to simple 3-dimensional contours. It is a suitable core material for dynamically loaded and shock absorbing sandwich structures.
Applications /
  • Marine:
    parts of hull (slamming area)
  • Road and Rail:
front-ends for trains, side skirts
  • Industrial Parts:
    dynamically loaded structures

Characteristics / extremely high impact resistance (non-brittle failure mode)
excellent fatigue resistance
cold formable to 3-dimensional contours
rot resistant
easily thermoformable
  • good ageing properties

Processing / hand lay-up
fibre spraying
resin injection
adhesive bonding
thermoforming
prepreg processing
