Re: Ceramic Helicopter Parts

[mtiplady]

Hi there,

I wondered if someone may be able to offer me some pointers with this one. Bit of a "weird" one but I'm studying for a HNC in electrical engineering, although one of my subjects is Materials Engineering. For an assignment, I have to identify component parts of a helicopter that utilise ceramic materials. The internet is a minefield of pages and if anyone could help me out or point me in the right direction as to where I might find the answers I would be greatly appreciative.

Also, I have to identify suitable applications for clay refractories, common refractories and high-grade refractories. Any takers on this one, too?

Regards,

Matt

1. Find several definitions for ceramics. If you are at all interested in Electrical Engineering then it is all gravy from there.
2. I associate refractory materials with heat because of the kind of work I do.

My all time favorite is that a ceramic is anything that is not organic or metallic. (See below) Do not use this definition in class. Use something more sophisticated.

CERAMICS.
Ceramics, one of the three major materials families, are crystalline compounds of metallic and nonmetallic elements. The ceramic family is large and varied, including such materials as refractories, glass, brick, cement and plaster, abrasives, sanitaryware, dinnerware, artware, porcelain enamel, ferroelectrics, ferrites, and dielectric insulators. There are other materials which, strictly speaking, are not ceramics, but which nevertheless are often included in this family.
These are carbon and graphite, mica, and asbestos. Also, intermetallic compounds, such as aluminides and Beryllides, which are classified as metals, and cermets, which are mixtures of metals and ceramics, are usually thought of as ceramic materials because of similar physical characteristics to certain ceramics.

For refractory applications, you may want to browse the websites of Resco and ANH Refractories.

Thank you both for your responses.

Unfortunately, I still haven't found the information for the second part of the question though - the dreaded refractories!

What I need to ascertain are what are the different bonding techniques of the three types of refractory, and what types of ceramic are produced from each one?
