Energy Absorption and Low-Velocity Impact Performance of Nanocomposites: Cones and Sandwich Structures

Abstract

The increasing need for high performance structures, in the energy and transport industry, demands a continuous development of new engineering materials. Unique mechanical properties together with low specific weight can be achieved by the combination of various constituent materials into one macroscopic composite material. Coupling of the high strength reinforcement with supporting matrix creates a novel material with the improved characteristics, which could never be obtained using either of the constituents separately. These types of materials are particularly desirable in structures where a high strength to weight ratio is of great importance. In this chapter, two case studies are provided one on nanophased sandwich composites with polyurethane/layered silicate foam cores and the other on thermoplastic glass-fibre and nano-silica reinforced nanocomposites.
