How do composite materials differ from traditional materials?
Composite materials combine different materials to create improved properties, while traditional materials are usually made of a single material.
Composite materials are more expensive than traditional materials.
Composite materials have lower strength compared to traditional materials.
Composite materials are made of a single material, while traditional materials combine different materials.
Why are composite materials considered lightweight?
Composite materials are lightweight because they are less durable than single-material products.
Composite materials are lightweight because they are made of heavy metals.
Composite materials are lightweight due to their low strength-to-weight ratio.
Composite materials are lightweight due to their high strength-to-weight ratio achieved by combining different materials.
What role do fibers play in composite materials?
Fibers provide reinforcement
Fibers increase flexibility
Fibers reduce weight
Fibers provide color
What are the environmental benefits of using composite materials?
Composite materials are not recyclable
Composite materials reduce carbon footprint due to lower weight
Composite materials emit harmful gases during production
