….Composite materials
, often shortened to
composites

or
called
composition materials
, are engineered or naturally
occurring materials made from two or more constituent materials
with significantly different physical or chemical properties which
remain separate and distinct.

What are Composite Products?

Composite History

An
understanding of composites seems to be
inherent in animal
behaviour, evident in the nest building of birds, bats and insects, for
example
.
Primitive
man used
animal
dung, clay, straw and sticks to form
composite structures that were literally the first building blocks of
civilization. Even the biblical
Noah's Ark was allegedly made of coal
-
tar
pitch and straw
, which could perhaps be the
first reported construction
of a reinforced composites boat
!


Moving
forward,
the 1830s onwards
saw new found industries
developing their own composite technologies such as laminated wood
,
alloyed metals and steel reinforced concrete. The earliest polymer
castings were developed by
Lepage

in France using albumen, blood and
wood flour to produce decorative plaques.


Phenolic, trade named Bakelite by its Belgian born US
inventor
L.H.Baekeland
, was the first wholly synthetic
plastic material
. As well as being used for decorative items
such as umbrella stands and pipe stems, phenolic was also
used to make components for the emerging electrical,
telephone and radio industries. Different fillers such as
wood flour, mica, asbestos and textile fabric were used to
enhance the heat resistance and insulating properties of
the resin.


For the first half of the 20th century, phenolic resins were
dominant. However the
emergence of the more versatile
and user friendly polyester resins in the 1940s

opened up
new composite markets.

Composite History

Wars tend to give a major boost to technological development
.
Such was the case in the early years of the Second World War, when
new structural materials were needed to complement the use of the
emerging radar technology.
Glass fibre reinforced polyester
composites fitted the bill perfectly

-

providing protective housings
for radar antenna, which are transparent to radio waves.


When the war was over, a new set of imperatives emerged which
further drove the wider use of glass fibre reinforced plastics, or GRP
as it was becoming known.


Composite History

Firstly
a major infrastructure and rebuilding program was
necessary and traditional materials such as steel were in short
supply. Secondly there was a growing sense of the need for
change and future orientation


especially when the
space race
got underway in the late
1950s.



Several industries quickly picked up on the very special benefits
that polyester composites

could offer. For example boat builders
found in GRP moulding an excellent way of mass producing hulls
and superstructures;
truck and car builders realized it was a
material that was pound
-
for
-
pound stronger than steel and did
not rust or dent
; and fabricators of tanks and pipes
recognized
GRP as a material that was lighter and more chemically
resistant than traditional materials

such as metals and
concrete.

Composite History

From the late 60s to late 70s, the oil crisis and cyclical global
recessions put the brakes on the runaway success of the
composites industry. The aftermath of this period saw a more
responsible approach emerge.


Nowadays the composites industry has settled into a mature
phase. Products, processes and applications are well established,
and developments are evolutionary rather than revolutionary.


Nevertheless new market sectors for composites continue to
appear, such as
wind turbine blades
-

an application undreamt of
previously.




Composite History

Likewise as new industries and new technologies emerge in this
new century, the
demand for tough and lightweight polyester
composite structures will be even stronger.



So who's to say that the next 50 years won't be even more
eventful than the last 50 years for the composites industry?


Composite History

Landmarks

1847

The Swedish chemist, Berzelius, one of the founders of modern chemistry,
makes the first laboratory cook of a saturated polyester


1894

Vorlander

studies glycol maleates in the laboratory, the earliest record of
chemical work with unsaturated polyesters


1920s

The pioneering Wallace Carothers studies polyesters prepared from ethylene
glycol and unsaturated acids


1922

The first polyester resins are produced as lacquers


1930s (late)

Researchers Bradley,
Kropa

and Johnson investigate the curing of
(monomer
-
free) unsaturated polyesters and report them to be insoluble and
infusible (thermo set) when cured. Carlton Ellis conducts experiments on using liquid
monomers, such as styrene, to give lower viscosity mixtures which cure much faster
than unsaturated polyesters on their own.



1935

Owens Corning introduces the first fine glass fibres


1941

First commercial application for unsaturated polyesters is in the USA, used for
castings.



Composite History

1942

The
US Rubber Company develops the first glass fibre reinforced polyester
composite.
Technology
is taken up by the US military
as
radomes for housing radar
equipment.
The
scarcity
and high cost of glass fibre restrict applications during
this period to defence and
aerospace.


1946

Boat
builders start to realize the potential that reinforced composites offer
to their
industry
, and in this year the first commercial boat hull is built in the USA.
The first cold
curing
systems are
introduced


1950s
The
first closed moulding processes are
patented


1951/2

Commercial
production of unsaturated polyester resins begins in Europe
.
The
composites industry
now has glass reinforcement in a totally compatible
form; products that
cold cure
in open moulds without any air inhibition; and,
most importantly, lower cost raw
materials
-

as polyester resins and glass
reinforcements become mass produced
.


1963

Carbon
fibre reinforcement is first
introduced
