Eurobond Adhesives Ltd have spent the last 12 months working with a global defence & security equipment manufacturer, helping them to improve the design of their ballistics protective helmets and shields used by the police and armed forces throughout the world.
Their bullet proof helmet is made from Kevlar. The outer shell is designed to have an inner adjustable cradle fixed to the inside so that the wearer can tighten or loosen straps in order to properly fit and protect the head from high velocity bullets, shrapnel or the effects of a blast wave. Typically these cradles are mechanically fixed to the outer Kevlar shell using rivets. This presented a problem as this mechanical fixing acted as a weak point in the design. Should a bullet or piece of shrapnel hit the metal rivet it would in itself become shrapnel and could penetrate the rivet hole causing serious injury or even death to the wearer. The design was changed to incorporate a series of toughened rubber strap loops bonded to the inside of the helmet. The inner cradle would attach to these points by simply threading the cradle strap through the rubber loops and tightening to fit. Eurobond’s CY403TB specially toughened rubber instant cyanoacrylate adhesive was selected for trials and evaluation. The helmets were taken to a high velocity ballistics range and were tested to destruction. CY403TB held up very well and remained securely bonded to the Kevlar wall. The adhesive was subjected to additional weathering and climactic tests, enormous shock and impact tests and passed with flying colours.
