Abstract

Composite materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure .composite material use in civil engineering, building infrastructure, automotive industries/transportation, sports industry, aircraft/military, submarine, ships, boats, biomedical, home appliances, ground transportation, chemical industries etc.

COMPOSITE MATERIALS

Introduction:

They are also called composition materials or shortened

to composites. They are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a

material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material

may be preferred for many reasons: common examples include materials which are

stronger, lighter or less expensive when compared to traditional materials.

Typical engineered composite materials include:

Composite building materials such as cements, concrete

Reinforced plastics such as fiber-reinforced polymer Metal Composites

Ceramic Composites (composite ceramic and metal matrices)

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. The

most advanced examples perform routinely on spacecraft and aircraft in demanding

environments.

FRP composites are no longer considered "space-age" materials

utilized only for stealth bombers and space shuttles. This versatile material system has

become a part of everyday life.

Why use composites? The biggest advantage of modern composite materials is that they are light as well as strong. By choosing an appropriate combination of matrix and reinforcement material, a new material can be made that exactly meets the requirements of a particular application. Composites also provide design flexibility because many of them can be molded into complex shapes. The downside is often the cost. Although the resulting product is more efficient, the raw materials are often expensive. Composite

Some key characteristics of Composites Materials:

Specific strength:

This is simply the rigidity or hardness of a material with regard to its weight. For example, a number of composites such as fiberglass share comparable impact resistance (bangability) with

steel and titanium at a fraction of the weight employed.

Expense:

Many composites can be manufactured with less cost than their traditional metal counterparts.

Application:

Because composites are composed of 2 or more "phases", they can be formulated to meet the needs of a specific application with considerable ease.

Process ability:

As most of you know, metal processing requires high amounts of thermal energy (heat). Plastics

and plastic based composites require less heat to mold or process the products. There is a constant desire to produce composites which can be processed at low temperatures but when

cured or set-up (paint drying or a mold cooling), they are very impact resistant and very heat resistant or fire retardant.

7

Applications of composite materials:

AIRCRAFT/MILITARY

Commercial, pleasure and military aircrafts, including components for

aerospace and related applications.

APPLIANCE/BUSINESS

Composite applications for the household and office including

appliances, power tools, business equipment, etc.

tennis rackets, snowmobiles, mobile campers, furniture, microwave cookware.

8

CORROSION-RESISTANT EQUIPMENT

Products for chemical-resistant service such as tanks, ducts and hoods,

pumps, fans, grating, chemical processing, pulp and paper, oil and gas, and

water/wastewater treatment markets.

ELECTRICAL

This encompassing market includes components for both electrical

and electronic applications such as pole line hardware, substation equipment, microwave

antennas, printed wiring boards, etc.

MARINE
