New Dyneema for Ballistic Protection Performance

25 June 2006

DSM Dyneema has introduced a new hard ballistic composite, Dyneema HB26, for protection of military and civilian vehicles against threats that include improvised explosive devices and assault rifles.

Roshield, a Danish manufacturer of composite protection solutions, has tested Dyneema HB26 in vehicle protection for the Danish armed forces. According to Peter Bertelsen, Managing Director, “Dyneema HB26 is used in all solutions Roshield has provided to the Danish Army to be used in Iraq. The solution was tested with other materials and proved to be the best in terms of weight and performance. It was tested with real ammunition at the right protection level (classified) by the Danish Army. We believe the army is satisfied with the solution, which has already proven its capabilities in saving lives in armed conflicts. Dyneema HB26 has been an improvement to work with in production and we have been happy to test it for DSM Dyneema.”

“The HB26 product delivers a spall liner effect against real weapons, not just in testing with small-calibre fragments as often seen in the market,” said Steen Tanderup, Marketing Manager, Vehicle Protection for DSM Dyneema. “It also shows very promising results for use in inserts and other personal protective gear.” He continued, “For manufacturers, the features of this material reduce the time required for cutting and stacking layers, and can speed up production.”

The material is a unidirectional (UD) composite made of several layers of Dyneema fibres, with the direction of fibres in each layer placed perpendicular to those in the adjacent layers. This unidirectional configuration allows the energy transferred from the impact of a bullet or other threat to be distributed along the fibres much faster and more efficiently than in conventional woven fabrics.
