Considering many potential applications of fiber reinforced metal laminates (FMLs) in sensitive structures, it is necessary to understand their mechanical behavior under impact loads. In this study, low velocity impact tests based on ASTM D7136 have been conducted on FMLs made of 1050 aluminum sheets and various types of fiber reinforced polymer (FRP) layers; namely E-Glass, Kevlar 49, and carbon T300 plain woven in the epoxy resin. Projectile energy, fiber type and the number of successive impacts are selected among important parameters that can affect the performance of FMLs. In particular, the effects of these parameters on the absorbed energy, contact force, front and rear face damage areas, central deflection and permanent deformation of FMLs have been investigated. For determining the damage area and central deflection of the specimens, an image processing method is adapted.

Survival of species such as geckos, spiders, flies, and crickets crucially depends on the interaction between hundreds of thousands of hairs or setae on their feet. Recently, many efforts have been made to fabricate adhesive pads inspired by natural biological systems. Fibres developed from nano molding can mimic the hairs of these species' feet and act as a dry adhesive pad. In this study, for the nanocasting of nano fibres, several porous silicon structures with desired dimensional and morphological characteristics were made by an electrochemical etching system. The adhesive strengths of produced adhesive pads were measured about 0.07 N/cm 2 in the normal direction and about 0.045 N/cm 2 in the shear direction in contact with a glass surface. Besides the experimental work, a quantitative model has been developed to model van der Waals interactions in adhesive pads. The results from the theoretical model show consistency with experiments.
