Heat treatment methods are the most
commonly used production steps because they can
interfere with all the mechanical properties of the
material without altering the chemical composition of
the metal in industry. Accelerated cooling is also one of
the most prominent points in the series production
process in these heat treatment methods. This method
is used in the manufacturing process of thin pearlitic
steel, double phase steel, rayon sheet steel which is used
for bainitic steel production, from construction bar to
profile in many different quality and size products. In
this study, S355J2 corrugated corrugations and
S275JR quality HEA-HEB structural section steels
were produced from hot rolled billets produced by
open casting method. Intensive inclusions were found
in both of the materials examined and it was seen that
they could not meet the mechanical strength values in
the sizes with low crushing rates. These materials,
especially those with low impact strength, have been
subjected to accelerated cooling to increase their
impact strength.

In this work, Brinell hardness test, impact test, bend test results of four different types of honeycomb composite
materials, which are important for todays in the Civil Aviation Sector and which have been undergoing significant
improvements over the past 20 years, have been investigated. The thickness of the mechanical properties of the composites
differed with the length of the part and the chemical resin used. The white material in 1,2 cm thickness is used in side and
ceiling in cargo area. The light yellow materials is 1,2 cm thickness and is used on the cargo floor and on the wet and dry floors
of Airbus, Boeing branded aircraft. Black materials (on wet floors) material in 9,9 cm thickness and used in Passenger Glasses.
Yellow Color resinized honeycomb composite in lyophilized form is 1cm thick and used on the bottom of cargo section.
Hardness measurements were carried out with a 2.5 mm ball and a load of 187.5 kg under the Brinell Hardness Tester . When
the hardness results were examined, when the white composite was damaged, the highest hardness value was found as yellow
composite (54,92 HB) value of black composite (26.02 HB). The open saddle stiffness is 31,43 HB.
