“…The maximum force, and penetration threshold values increased with the increase of the impactor diameter. Reddy et al [23] studied the effect of different composite thicknesses and different energy levels on low velocity impact behavior of glass fiber laminated composites. As the impact energy and thickness increased, the maximum force and contact time increased.…”

As it is known, impact damage is a major mechanical phenomena for composite materials especially used in the aerospace structures. The factors affecting the impact behaviour of the composites depend on the impactor systems as well as the target material. In this study ply number and impactor geometry effects of carbon fiber reinforced epoxy composites were investigated by impact tests. In this context, drop weight impact tests were carried out at 6J, 12J and 24J energy levels by using hemispherical impactors with 10 mm and 20 mm diameters. Laminated composites were manufactured in 6, 10 and 14 plies with vacuum infusion method. The effects of laminate thickness, impactor diameter and impact energy effects on the force, velocity, absorbed energy and damage surfaces were investigated. It is observed that impactor geometries and velocities caused the different damage mechanisms in composites and impactors played an important role in determining the penetration and perforation behaviours of composites.

“…Likewise, some researchers stated that nanoparticle inclusion can substantially reduce the damage area of composites and FMLs [43,61,78,90].The analysis of the total damage area (Figure 23(c)) indicates that increasing impact energy is accompanied by increasing FML damage area. Similar results have been recorded in other works [26,41,93,94]. Furthermore, another study [13] proved that the delamination damage on the aluminum-composite interface is greatly affected by impact energy.…”

“…The fiber fracture and fabric splitting in the warp and weft yarn directions depends on the amount of the impact energy available to break them. The low velocity impact strength of fiber reinforced polymeric composites depends on many factors, as matrix and fiber properties, their compatibility, fabric weave type, damage strength and quality of fiber-matrix interface, plate thickness [11], shape and diameter of the impactor [12] and initial experimental test parameters (velocity and height). In order to improve the impact performance of the laminate composites as reinforcements can be used different types of fiber/fabric plies (carbon-glass [13][14][15], carbon-aramid [16], carbon-basalt [17], glass-basalt [18], basalt-aramid [19], etc.)…”

The low velocity impact response of hybrid epoxy composites reinforced with plain weave fabrics, ply orientation at various angles and filled stratified matrix was analyzed in this study. The hybrid epoxy composites were subjected to impact tests at 45J and 90J of energy levels with drop weight impact machine. The damaged areas were investigated by visual inspection of impacted and non-impacted surfaces and by tomographic images. It was found that the replacement of certain carbon inner plies with glass ones and the modification of fiber orientation improved the damage resistance of the hybrid composites with aramid outer layers subjected to impact loading at 45J of energy level.
