The microstructure and mechanical properties of three dimensional integral braiding composites

摘要

Three dimensional Integral braiding composites are advanced composites reinforced by three dimensional braiding fabrics (preforms). These kinds of composites have a non-laminated, integrated structure and have superior interlaminate properties and other properties which can make them form main bearing load components and high functional components. The microstructure and main mechanical properties including tensile property, bending property, compress property, fatigue property, impact property, and the relationship between microstructure and these properties of three dimensional braiding composites are researched in this paper, which can provide necessary data for the design and application of three dimensional braiding composites.
