Composite Flashcards
What are composites and how are they different from conventional materials?
Composites are materials made up of two or more constituent materials with significantly different physical or chemical properties. They differ from conventional materials in their properties, structure, and behavior.
What are the advantages of composites over conventional materials?
Composites have many advantages over conventional materials, such as high strength-to-weight ratio, corrosion resistance, and design flexibility. They can be tailored to meet specific performance requirements and are often used in high-performance applications.
What are some common types of composites and what are their uses?
Some common types of composites include fiber reinforced composites, polymer matrix composites, and ceramic matrix composites. They are used in applications such as aerospace, automotive, construction, and sports equipment.
What is the role of the matrix material in a composite?
The matrix material in a composite holds the reinforcement material together and transfers load between the reinforcing fibers or particles. It also protects the reinforcement material from environmental damage.
What is the role of the reinforcement material in a composite?
The reinforcement material in a composite provides strength and stiffness to the composite. It is usually in the form of fibers or particles and is embedded in the matrix material.
How are composites manufactured?
Composites can be manufactured using a variety of methods, such as hand lay-up, filament winding, and injection molding. The manufacturing method depends on the type of composite being produced and the desired properties.
What are some challenges associated with the use of composites?
Composites can be expensive to manufacture and may require specialized equipment and skills. They can also be brittle and susceptible to damage from impact or fatigue.
How are composites being used to improve sustainability?
Composites are being used to improve sustainability by reducing weight and increasing fuel efficiency in transportation applications. They are also being used to replace traditional building materials in construction, which can reduce energy consumption and environmental impact.
