Core Materials

Sandwich composite laminates structure is a classic application of composite material on actual aircraft structural. Dealing with low-velocity impact damage and residual compressive strength of sandwich composite laminates, explicit finite element method of ABAQUS/Explicit software was adopted to simulate low-velocity impact and compression process. Impact response and invalidation on compression between sandwich composite laminates with different core materials and regular composite laminates were compared. The simulation results indicated that softer core materials can absorb more impact energy, reduce the structure damage and enhance the residual compressive strength after impact.

The Impact

The residual compressive strength of a foam core sandwich panel after low-velocity impact was studied by using experimental and analytical methods. The test specimens were compressed uniaxially after they were subjected to a low-velocity-impact. From the observation in the test, one can conclude that the subsequent core crushing around the impact region is the major failure mode in the sandwich structure. A failure criterion named Damage Propagation Criterion was proposed to predict the residual compressive load bearing capability of the low-velocity impacted composite sandwich panel. The characteristic value used in this failure criterion can be calculated by an analytical model developed or by conducting the Sandwich Compression after Impact test.
