✦ Synopsis

Some mechanical properties of particulate-Ðlled polyethylene/epoxy and aramid/epoxy laminates are reported, following earlier work with particulate-Ðlled glass/epoxy laminates. The behaviour of the organic Ðbre laminates was di †erent from that of glass Ðbre ones, investigated and reported earlier.

There was an increase in compression strength with increasing Ðller content, with both kinds of organic Ðbre reinforcement. The interlaminar shear strength values were signiÐcantly lower for the polyethylene laminates than the aramid ones at all Ðller concentrations, and they fell to little more than 10 MPa at high Ðller levels. However, the impact damage zone in drop weight tests was generally smaller for the polyethylene laminates, and the visible crack damage was less apparent than in the aramid ones. The Ñexural strength and modulus values are also reported.
