Toughened Rigid Foam Core Material For Use In Sandwich Constructions
Source abstract
Abstract
Tensile tests were performed at low temperatures and for high strain rates are used to analyze energy absorbance transitions for a cellular material, Divinycell HD. Besides the glass transition temperatures transitions are found for both low temperature and for high strain rates. The low temperature transition is found to be a mechanical failure mechanism that within a limited temperature interval reduced the elongation by approximately 90%. The corresponding reduction in elongation for high strain rates is of the order of 50%. It was also demonstrated that cell size and cell size distribution, in combination with density, strongly influence the energy absorbing capability and stress intensity factor, K 1C . This work also shows special application fields appropriate for the good static properties in combination with improved ductility and energy absorption capability of Divinycell HD.
