A viable solution to the ever-demanding weight-saving target in aerospace industry is the replacement of conventional engineering alloys with composite materials in primary structures. A major concern to the effective use of composite laminates is the substantial reduction in the compressive strength when the contact force has exceeded the delamination threshold load (DTL). This paper focuses o...

Abstract Hybrid fiber composites are widely used to improve the anti-penetration performance. Carbon/Kevlar hybrid in aircrafts and safety devices, thanks strong toughness of Kevlar fibers high strength carbon fibers. In present work, contact force under oblique impact is derived. The viscoelastic constitutive model layer investigated dissipation energies for different velocity impacts simulate...
