“…It is possible that the delamination failure mode could be suppressed with the use of a higher shear strength matrix [19], or by a stitching [20] or 3D weaving/braiding approach [21,22] to improve the delamination resistance and increase the fraction of fibers in the load carrying directions. Finally, if these strategies delay the onset of buckling and delamination failure modes, the use of nanoscopic reinforcements of the polymer matrix [23,24], might enable the stress at which the plastic fiber micro-buckling failure mechanism is activated to be raised.…”

“…[2][3][4]. Research can thus focus on either different core materials including foams, honeycomb, cork, balsa wood, coconut and other artificially constructed truss or sheet structures [4][5][6][7][8][9][10][11] or different face sheets as aluminium, carbon, glass, aramid reinforced composites etc. [3,12].…”

Abstract. Aircraft grade of structural sandwich plates has been studied to determine the influence rate of particular face sheets adjustments on impact energy absorption. The face sheets were fabricated by carbon fibre reinforced plastic (CFRP) laminas using unidirectional reinforcement with either cross-ply [0/90]n or angle-ply [±45]n orientation of fibres. A core of the sandwich plates was then formed by aluminium honeycomb. The impact properties of small unnotched sandwich specimens were measured by instrumented Charpy impact test device. Assessment of force-displacement curve, loading process and failure mode was carried out for each specimen type to determine a general trend for increasing the impact properties of sandwich structures.

“…It is due to their unique structural, physical, and mechanical characteristics such as light weight, high strength to weight ratio, high bending stiffness, excellent thermal and acoustical insulation [20][21][22][23][24][25][26][27][28]. The outstanding properties make sandwich constructions attractive for use in thermal protection systems.…”
