Sandwich Core

Radomes are usually constructed from sandwich structures made of materials which usually have a low dielectric constant so that they do not interfere with electromagnetic waves. Performance of the antenna is increased by the appropriate assortment of materials enabling it to survive under marine applications, and it depends on composite strength-to-weight ratio, stiffness, and resistance to corrosion. The design of a sandwich core submarine radome greatly depends on the material system, number of layers, orientation angles, and thickness of the core material. In this paper, a conceptual design study for a sandwich core submarine radome is carried out with the help of finite element analysis (FEA) using two unidirectional composite materials—glass fiber reinforced polymer (GFRP) and carbon fiber reinforced polymer (CFRP)—as a skin material and six different core materials. Conceptual designs are obtained based on constraints on the composite materials’ failure, buckling, and strength. The thickness of the core is reduced under constraints on material and buckling strength. Finite element analysis software ANSYS WORKBENCH is used to carry out all the simulations.

Fluctuating Wind

The author puts forward a new insulation cross arm, uses the insulation and high strength composite materials (FRP), to replace the steel applied to the RPC pole cross arm, this not only has a full bar maintenance-free features, and can shorten transmission corridor again, for the construction of resource intensive transmission lines has important practical significance. In addition, this paper uses finite element analysis software ANSYS, considering the influence of fluctuating wind, in the modal analysis and dynamic response illustrates the actuality of cross arm application of composite materials.

Single Filler

The distribution of interparticle distance, based on a Voronoi tessellation, is found approximately for a hard-core Gibbs process. The moments of this distribution are then used as input for finite-element analysis of the region surrounding a single filler sphere within a composite material. Statistical analysis provides close bounds for overall elastic properties of the material. Results from finite-element analysis can therefore be applied to real composite materials; reasonable agreement is found with a particular set of experimental data.
