Question 1

What Is Composite Material?

Accepted Answer

Composite materials are a combination of two materials with different physical and chemical properties. When they are combined, they form a material that is specialized to perform a certain function, for example, to become stronger, lighter, or resistant to lightning.

They can also improve strength and stiffness. The reason for their use over conventional materials is that they improve the properties of their base material and are applicable in many situations. There can be many reasons for preferring new content.

Question 2

Why Use Composites?

Accepted Answer

One of the main reasons for using composites materials instead of traditional materials for components is weight savings. While composites are lightweight, they can also be stronger than other materials; for example, reinforced carbon fiber can be up to five times stronger than 1020 grade steel and hold only one-fifth of the weight, which makes it stronger for structural purposes.

Another advantage of using composites over conventional types of material is its thermal and chemical resistance as well as electrical insulation properties. Unlike traditional materials, composites can have many properties that are not often found in a single material.

Question 3

When Should You Use Composites?

Accepted Answer

As With all engineering materials, composite have particular strengths & weaknesses, which must be considered in the specified step. Composites are by no means the right materials for every job.

However, a major driving force behind the development of composites has been that the combination of reinforcement and matrix can be changed to meets the required final properties of a component. For example, if the finals component needs to be fire-resistant, a fire retardant matrix may be used at the development stage so that it has this property.

Weight reduction:- The primary reason for choosing composites is to improve the specific strength/hardness (strength/hardness specific per unit weight). It helps to reduce fuel usage or increase acceleration or range in transport.

This allows for easier, faster installation or faster movement of robotic arms and lowers to supporting structures or foundations. It improves upward stability in ships and offshore structures and buoyancy for deep-sea applications.

Durability and Maintenance: - Composites do not do rust, which is especially important in marine & chemical environments. The need for Maintenance & painting is reduced or eliminated. Compound bearings for marine engines and bridges do not require lubrication or wear.

Combine excellent fatigue resistance and composites can increase product lifetime by manifold in many applications.

Additional Functionality: - Composites are thermal insulators that are good for fire and explosion protection or cryogenic applications. Electrical insulation is useful for lineside railway structures and radar transparency.

Question 4

What Are Composites Made Of?

Accepted Answer

The Composite, also known as fiber-reinforced polymer (FRP) composites, are composed of a polymer matrix that is an engineered, man-made, or natural fiber (such as glass, carbon, or aramid) or other reinforced material. - Combined with reinforced.

Together. The matrix protects the fiber from environmental & external damage & transfers the loads between the fibers. The fibers, in turn, provide strength & stiffness to the matrix – and help it resist cracks and fractures. In many of our industrial products, polyester is the resin matrix, and glass fiber is the reinforcements.

Question 5

Natural and Synthetic Composites:

Accepted Answer

Composites can be naturals or synthetic. Wood, a naturals composites, is a combination of cellulose or wood fibers and a substance called lignins. Fibers give Wood its strengths; Lignin is the matrix or natural glue that binds & stabilizes them. Other composites are synthetic man-made

Question 6

Are Plastics Composites?

Accepted Answer

Not all plastics are composites. In fact, most plastics—which are used in toys, water bottles, and other familiar objects—are not composites. They are pure plastic. But many types of plastics can be strengthened to make them stronger. This combination of plastic and reinforcement can produce some of the strongest, most versatile materials for their weight ever developed by technology.

Question 8

Structural Composite Materials:

Accepted Answer

Structural composites materials can be classified as follows:

#1. Sandwich Structures

They are composed of a core and layers. They allow to improve mechanical properties but without excessive increase in weight. They also improve thermal and acoustic insulation.

#2. Monolithic Structures

Parts with a complex geometry, created by overlapping fabrics with special orientations that allow specific characteristics to be obtained. Such a part is intended to withstand the heaviest structural loads.

Question 9

Brief History:

Accepted Answer

The Human has used composites for thousands of years. The first man-made composites were made in Iraq by the Mesopotamians in 3400 BC. Ancient societies glued wooden strips on top of each other at different angles to make plywood. Thereafter, around 2181 BC. The Egyptians began to make death masks from papyrus soaked in linen or plaster.

Later, both of these societies began to fortify their material with straw to strengthen clay bricks, pottery, and boats. In 1200 AD, the Mongols began making compound bows that were incredibly effective at the time.

These were made of woods, bamboos, bone, cattle tendon, horn, and silk bound with pine resin. After the Industrial Revolution, synthetic resins began to take a solid form using polymerization. In the 1900s, this new knowledge about chemicals led to the creation of various plastics such as polyester, phenolic, and vinyl.

The development of synthetics then began; Bakelite was created by the chemist Leo Baekeland. The fact that it did not conduct electricity and was heat resistant meant that it could be widely used in many industries. The 1930s were an incredibly important time for the advancement of composites.
