Thick panel glass/polymer composites are being considered as a structural c
omponent in ballistic armor. A new experimental technique has been develope
d to perform dynamic bi-axial testing on laminate composites. In-plane ulti
mate compressive strength of the composite is compared for various combinat
ions of bi-axial stress and strain rate. Evolution of the damage in the com
posite and subsequent kink-band formation is studied by the use of high-spe
ed photography and electron microscopy. (C) 2001 Elsevier Science B.V. All
