Im doing a ms powerpoint for Carbon-fiber-reinforced polymer. What can each of my slides be about?

First you need to think about who will watch the presentation. Is it to give an introduction to these polymers to people with no background? It is to engineers that work with these materials every day? Is it a presentation to management about the benefits of these materials? The audience will determine what slides you make. For example if your audience knows nothing even about polymers generally you will need a slide or two to explain what is a polymer. You also need a slide for almost all audiences about why they should care about the subject, what are the advantages of carbon fiber reinforced polymers? Are they lighter, cheaper, stronger, more manufacturing friendly, etc. Finally always have a beginning slide that outlines what you will talk about and a final slide to summarize what you just talked about. As a final hint practice what you are going to say before you give the presentation. Good luck.
