Laminated Core Material

By increasing the core thickness you can increase the stiffness of the sandwich without substantially.

Laminated core material. The c i core configuration is made of one cut core rectangular toroidal or any other shape and one laminated i bar as shown in figures 3a 3b. The coefficients of thermal expansion cte of the core the laminate material and the adhesive must be compatible to ensure that thermal cycling doesn t cause debonding. It is however a conducting loop that experiences a changing magnetic field it will therefore have small currents induced in it these are called eddy currents. With the explosion of closed molding methods over the last few years new grooved core forms have been developed that can be used as the resin infusion media without the need.

Finally on the base there s a thin layer of hard moisture proof board. This can provide a dramatic increase in stiffness for very little additional weight. The bulk of the material made from low grade fiberboard. The inner skin is laminated onto the top of the core material effectively sealing it.

A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites. Sandwich core laminates of this type are used to stiffen various composite applications such as boat hulls automobile hoods molds and aircraft panels. The figure below shows a cored laminate under a bending load. The core in its final assembly has the same shape as an el ei or f stamped lamination and is similar to the configuration of a double c core.

Offerings include a variety of structural honeycomb cored and foam cored products in either pre cut or standard sizes closed molding cores including nidafusion composite panels kiln dried end grain balsa. The purpose of a core in a composite laminate is therefore to increase the laminate s stiffness by effectively thickening it with a low density core material. Nida core s broad portfolio of high strength low weight engineered materials provides solutions in general industrial markets including transportation marine and renewable energy. The core is not designed to have any currents flow through it.
