Q:

What are the materials that make flaps and slats?

A:

Flaps and slats are usually made from the same materials as the wing itself: aluminum or some combination of other metals (composite). The main forces on the flap and slats are drag and lift. The slat and flap work together to increase surface area of the wing, and therefore increase lift. When landing, both the flats and slats angle down to try and catch as much wind as possible and slow down with drag.
