Assessment of Impact Resistance in Composite Sandwich Structures: An Experimental and Numerical Approach

Abstract: This paper presents an evaluation of the impact resistance of composite sandwich structures with regard to the type, design, and characteristics of impact in three parts. Structure consisting of lightweight core and reinforced face layers are widely used in all fields where high strength to weight ratios is desirable. It has established that carbon and glass fiber face sheets make quite different properties in impact absorption and structural resilience as foam or honeycomb cores. Both experimental and numerical formulations offer valuable results with few limitations toward the analysis of damage mechanisms within composite materials. A few suggestions for future work are related to further investigations of the constituent materials, improvements in numerical simulations, and the creation of purpose-oriented design recommendations for broader utilization of these structures in critical-end use applications
