Analysis of Composite Structures

The mechanical analysis of fiber-reinforced composite materials, which follows, is approached at three different levels  

The macromechanics of several layers making up a laminated composite panel structure 

Notation for Composite Lamina and Constituent Material Properties 

= Volume fraction of fibers = (volume of fibers/total volume of composite) 

Macroscopic Properties of Unidirectional Lamina (subscripts L and T refer to the in-plane longitudinal and transverse directions of the lamina)

The design and analysis of composite structures relies on experimental data. Testing of composites serves a variety of purposes such as the characterization of constituent materials i.e. the fiber, matrix and fiber/matrix interface, verification of the micromechanics analysis including the effects of curing stresses, temperature and moisture, as well as life prediction through accelerated testing[l].

Quantitative analysis of ESP is important for several reasons. The precise knowledge of the ESP is necessary to allow comparison of atomic potentials in different structures, analysis of composition (partial occupancy) and chemical bonding (crystal formation, structure property relations).
