Background

Background

Composite materials (or composites for short) are engineered materials made from two or more constituent materials with significantly different physical or chemical properties and which remain separate and distinct on a macroscopic level within the finished structure. (Wikipedia)


Background1

Background

Arg-e-Bam, IRAN.

Constructed in 20 hectares, More than 1400 years ago.

The most primitive composite materials comprised straw and mud in the form of bricks for building construction


Background2

Background

There are two categories of constituent materials: matrix and reinforcement. The matrix material surrounds and supports the reinforcement materials by maintaining their relative positions. The reinforcements impart their special mechanical and physical properties to enhance the matrix properties.


Backgrund

Backgrund

The most famous composite is called fiberglass which is made of glass fibers as the reinforcement and polyester (or epoxy) resin as the matrix.


Applications

Applications

Most industries have a connection with composite materials.

Due to high strength and light weight of composite materials, aerospace industries use composite materials. Carbon fibers and fiberglass are used in Aerospace industries.

Leading edge of the wings, vertical and horizontal tails, compressed air tanks, nose cone, fuselage, etc. are made of composite materials.


Applications1

Applications

Composite fuselage


Applications2

Applications

Full composite glider


Applications3

Applications

Composite nose cone


Applications4

Applications

Composite sandwich panel wing


Allications

Allications

Full composite high speed boat

Duse to high durability of composite materials in water and wet climate, most boats and yachts are made by composite materials.


Applications5

Applications

Boat interiors


Applications6

Applications

Composite Bridges


Applications7

Applications

Composite body

Automobile industry uses several kind of composite parts.

Sport cars employ composites to reduce the weight.


Applications8

Applications

Composite body


Applications9

Applications

Most sport equipment are sued by fiberglass.

Ski and ski pole are made by composite materials.


Application

Application

Fiberglass finishing

Civil Engineers are familiar with composite materials. They use composites to reinforce the structure against seismic loads.


Applications10

Applications

Composite swimming

pool


Applications11

Applications

Renovation by fiberglass


Applications12

Applications

Composite Domes


Applications13

Applications

Reinforcement of Building by composite materials


Applications14

Applications

Wind turbines are made composite materials. Some of their blades have 100 m length.


Applications15

Applications

As a general rule, when one needs light structure with high strength, composite materials are the best choice.

Some part of the body of high speed trains are made by composites. Further more the interiors are made by composites.


Applications16

Applications

High speed Japan train


Applications17

Applications

Monorail Interior, Malaysia


Applications18

Applications

Monorail body, Malaysia


Applications19

Applications

Also other thousands of applications can be found if one search “composite” or “Fiberglass” in internet!!


Manufacturing technologies

Manufacturing Technologies

  • Every composite parts needs master and mould.

  • The common manufacturing techniques are:

    • Hand layup.

    • Spray Up.

    • Resin Transfer Molding (RTM).

    • Resin Infusion.

    • Filament Winding.

    • Sheet Metal Compound (SMC).

    • Bulk Molding Compound (BMC).
