Experimental analysis of ice sphere impacts on unidirectional carbon/epoxy laminates

“…Finally, for each combination of ice mass and laminate thickness, the minimum kinetic energy (failure threshold energy) that produces any type of damage was obtained. More recently in 2009 Asp and Juntikka [35] performed experimental tests of ice spheres (up to 50 mm) on non-crimp fabric composites analysing, by means of micrographs, the damage mechanisms that appear in that type of laminates. In the same year Hong et al [36] performed experimental tests of ice particles (around 3 mm in diameter) at very high velocity (up to 900 m/s) on fabric laminates; the authors analysed the damage pattern and also the debris produced due to the high velocity impact.…”

Analytical modelling of high velocity impacts of cylindrical projectiles on carbon/epoxy laminates

“…Experimental results of steel projectiles impacting CFRPs at high speed velocities can be found in papers due to Cantwell and Morton [11], Sun and Potti [12], Larsson [13], Bland and Dear [14], López Puente et al [15,16], Will et al [17], Tanabe et al [18,19], Hammond et al [20], Hosur et al [21], Herzsberg and Weller [22], Caprino et al [23] and Hazell et al [24]. Other authors used projectiles made of different materials: Kim et al [25] utilized ice spheres, Chambers et al [26] lead pellets and Asp and Juntikka [27] ice spheres and granite stones.…”

Soft impacts on aerospace structures

“…Similar photographs from Asp and Juntikka [193] shown in [194], a study that focuses on impact-induced delaminations to laminated composites and in [161] where both experiments and simulations show the propagation of longitudinal cracks oriented along the direction of travel.…”
