Question: What materials and chemicals are used in making a rocket

Hey,

🔩 Materials Used to Build a Rocket
These materials must be strong but light, so the rocket can fly high without breaking.

Aluminum alloys – Lightweight and strong; used for the rocket’s body (like a metal skeleton).

Titanium – Very strong and heat-resistant; used in engine parts.

Carbon fiber – Super light and strong; used in modern rockets.

Ceramics and heat-resistant tiles – Protect the rocket from extreme heat when re-entering Earth’s atmosphere.

🔥 Chemicals Used to Power the Rocket
Rockets need fuel and oxidizers to create a powerful blast (called thrust).

Liquid Oxygen (LOX) – Provides oxygen to burn the fuel in space.

Liquid Hydrogen (LH2) – A super-light and powerful fuel.

RP-1 – A special type of purified kerosene (like jet fuel).

Solid Propellants – Used in some rockets (like space shuttles); they’re a mix of fuel and oxidizer packed into a solid block.

💥 Fun Fact:
When fuel and oxidizer mix in the rocket engine, they explode in a controlled way, pushing the rocket upward with huge force -Newton’s 3rd Law: Every action has an equal and opposite reaction!
