Abstract

Protective helmets for motor-cyclists and/or motorists consisting of high density composite materials,essentially based on a polyisocyanuric matrix, having a density equal to or higher than 500 and preferably than 1,000 kg/m<3>, containing reinforcing fillers, wherein the polyisocyanuric matrix derives from a repeating structural unit having the formula: <CHEM> wherein at least one X group represents the group -R1-NCO and at least one X group represents the group: -R1-NH-CO-OR2(-OCO-NH-R1-NCO)n.
