The technology of lamina ... impact test machine, which was conveniently equipped to evaluate the angular variation and the acceleration of the impacting mass. Preliminarily, non-destructive ultrasonic controls were performed to check that the ...
Impact tests were conducted using a guided drop-weight test rig in ascending energy to 24 J/layer nominal impact energy. Metallographic microscopy was used to observe the damage characteristics of the perpendicular cross-section of the impacted laminates after a micropowder polishing treatment.
Similarly, test specimen properties would be expected to be similar to those of a panel with equivalent length and width dimensions, in comparison to those of a panel significantly larger than the test specimen, which tends to divert a greater proportion of the impact energy into elastic deformation.

Alternatively, the test panel may be subjected to a prescribed level of impact energy, selected to induce local damage without penetration. In fact, when the intent is to induce and then detect damage that may not be evident by visual inspection of a structure, surface damage may be barely visible.

Our high pressure laminate panels are abuse-resistant, impact-resistant and scratch-resistant. They’ll stand the test of time no matter how often they’re touched, leaned on or bumped into with mops or vacuums, and you’ll never have to repaint your wall surfaces again.
ASTM D 4255 describes both 2 Rail and 3 rail methods of determining the in-plane shear strength of a composite laminate panel. In the 2 Rail test (Method A) a laminate panel specimen is clamped between loading plates and yokes and then subject to shear loading.
Mechanical Testing of Composites ... COMPRESSION AFTER IMPACT TESTING. Damage tolerance is a major concern with composite laminates. Compression after impact (CAI) testing provides a measure of damage tolerance. The CAI test is usually conducted on a rectangular laminate panel. The test consists of two parts:
