National Characteristics
Which websites can I use to learn more about the general characteristics of materials. Just the basics though?

I am doing a BTEC National Diploma in Engineering. My latest assignment involves the characteristics, appearances and structures of the following materials; Metals, polymers, ceramics and composites. Most of the websites I have found so far are too advanced or are websites for the sale of such materials. I need the basics !!!
