  • Data for Glare-5, "Application of Fibre-Metal Laminates", Polymer Composites, August 2000, [Absorbed Impact Energy (maximum) before Perforation]
  • Data for DYN 1, and DYN 5 (Structures based on Kevlar reinforcements), form "Impact Testing in Formula One", A. N. Mellor, (Absorbed Impact Energy within displacement of 100 mm) Transport Research Laboratory, Crowthorne, England, ("ICRASH 2002" International Conference, February 2002, Melbourne)
  • ELACO® - Novel High Impact Strength, Elastic ELACO® Fibre Metal Laminate Structures.

Some, average characteristics of new ELACO® Laminates are:

  • Tensile Strength s > 1000 MPa, (average) - Density ? = 1304 - 2448 kg / m 3 , - Peak Impact Force F up to 184.3 kN (without penetration), - Impact Energy Absorbed E A up to 3985 J (without penetration), - Deflection: 13 - 43 mm, - Young's modulus of elasticity E = 33 GPa, (average) - Poison's ratio n = 0.33 (average).
