Modern Materials
Metal foams
Typically, only 5-25% of the foam is the metal, and this allows the material to retain much of its strength but without the density or weight of a solid metal.
Metal foams are often used in vehicles such as planes and cars as they absorb shock effectively if the vehicle crashes.
Metal foams are a strong but lightweight modern material produced by injecting a gas or foaming agent into a molten metal.

What are they?
A modern material is a material that has been designed recently, and that has been engineered to have improved properties.
Concrete, aluminum and steel are all commonly used modern materials. But there are more recent additions that include materials that have changed the way we manufacture and use products.
Graphene
We are yet to manufacture it in large enough quantities to prove this. In theory it could provide body armour that is bulletproof, invisible and almost weightless.
Graphene is a single carbon layer material, which is hypothetically 100 times stronger than steel.
Titanium
Titanium is a modern material and is used in sporting and medical applications, such as replacement hips joints and high-performance bicycles.
It is an excellent material for these purposes as it has a high strength-to-weight ratio and is resistant to corrosion.
Nanomaterials
Nanomaterials are tiny particles of 1 to 100 nm, that can be used in thin films or coatings such as the oleophobic coatings on smartphone screens that repel greasy fingerprints, or hydrophobic materials that repel water.
