Abstract
A thin elastomeric sheet material with enhanced puncture resistance is prepared by embedding thin plate-like non-elastomeric particles in an elastomeric matrix so that the non-elastomeric particles form lamellae of overlapping plates. The interaction of the embedded particles and the matrix results in a composite sheet material have puncture resistance, at a load application rate in the relevant range for a surgical needle or the like, far superior to either the particles or an elastomeric sheet of equivalent thickness.
