CARBON FIBRE.

What is the limitations of composite materials?

When compared to wrought materials, composites are more brittle and more easily damaged. There are some issues with their repair. For instance, materials need refrigerated transport and storage. Similarly, special equipment is required for hot curing in many cases.

What advantages do composite materials give engineers?

Here’s why:

Flexibility in design. Designers love composites for good reason.
Lightweight.
Strength.
Corrosion resistance.
Durability.
Reduced maintenance.
Good insulators.
The cost of using composite materials explained:

What are the advantages of composite material?

Other key advantages include:

As molded dimensional accuracy. Tight tolerance, repeatable moldings.
Chemical Resistance.
Consolidated Parts and Function.
Corrosion Resistance.
Design Flexibility.
Durable.
High Flexural Modulus to Carry Demanding Loads. High Impact Strength.
High Performance at Elevated Temperatures.

What are disadvantages of composites?

Composites have disadvantages such as high raw material costs and, in most cases, high fabrication and assembly costs, poor strength in the out-of-plane direction where the matrix carries the primary load, susceptibility to impact damage, and greater difficulty in repairing them when compared to metallic structures.

What are composites used for in engineering?

Composite materials are generally used for buildings, bridges and structures such as boat hulls, swimming pool panels, race car bodies, shower stalls, bathtubs, storage tanks, imitation granite and cultured marble sinks and counter tops.

What are the applications of composites?

Why is composite material important in engineering?

The greatest advantage of composite materials is strength and stiffness combined with lightness. By choosing an appropriate combination of reinforcement and matrix material, manufacturers can produce properties that exactly fit the requirements for a particular structure for a particular purpose.

What are the disadvantages and limitations of composites?

Composites are more brittle than wrought metals and thus are more easily damaged. Cast metals also tend to be brittle. 2. Repair introduces new problems, for the following reasons: Materials require refrigerated transport and storage and have limited shelf lives.
