An impact resistance and fatigue-testing study reports that Telene, a thermoset polydicyclopentadiene (PDCPD), used as a matrix in a glass fiber composite, demonstrated improved impact strength and fatigue resistance for products subject to high stress factors.  

The study, released by the Department of Materials Engineering at the University of Leuven, Belgium, found that Telene exhibited 50% greater resistance in impact testing and four times longer life in fatigue testing than epoxy samples did, while maintaining the same overall tensile strength.    The study compared Telene alongside an equivalent epoxy composite commonly used in the laminate process.  

While the epoxy-based laminates used with glass fibers exhibited revealed early local damage and loss of mechanical properties, Telene reportedly retained its mechanical characteristics throughout the extended testing protocol, until break. 

An abstract and the full study are available from Science Direct.
