Eli5: Strong yet brittle?

711 viewsEngineeringOther

Some materials are considered very strong, yet they are also very brittle. To me this sounds a bit counterintuitive so please explain to me how a material like carbon fiber for example, is considered strong but yet breaks easily.

Take concrete: you can put a building onto a column not even a meter across. But you can whack that same column into pieces with a sledgehammer.

Now take rubber. It will just squish and roll over if you try to put pressure on it. If you try to sledgehammer it, you’ll just receive your hammer back in your face though.
