The deformation on cylindrical surfaces of holes in tensile-loaded laminated composite specimens was measured using new moire interferometry techniuqes. Two composite tensile specimens, fabricated from IM7/5250-4 pre-preg with ply layups of [0 deg_4/90 deg _4]_(3s) and [+30 deg _2/-30 deg _2/90 deg _4]_(3s), were examined using the newly developed morie interferometry techniques. Circumferential and thickness direction displacement fringe patterns (each 3 deg wide) were assembled into 90 deg-wide mosaics around the hole periphery for both composite specimens.
