Aluminium
Honeycomb panels are used to form lightweight, high
strength sandwich units that are extremely rigid. The Aluminium
Core is manufactured in several grades from 3003 general
applications to 5052 and 5056 for use in Military applications.
Aluminium 3003 as a core material has the
following attributes
- Temperature usage up to 175 ° C
- High Thermal Conductivity
- Flame resistance
- Moisture and Corrosion Resistance
- Fungi Resistant
- High Strength
- Low weight
Aluminium Honeycomb Panels Core material wafer
block is stretched into a sheet of Hexagonal structure on
purpose designed computer-controlled equipment to give a
consistent cell dimension. The walls of the cells can have
micro perforations to allow movement of air between adjacent
cells equalizing pressure in environments with rapid temperature
variation.
The cell size, depth of material, thickness of cell walls
and grade of Aluminium are all variable to suit specific
requirements and tailored to impart the correct properties
in the final manufactured units.
The aluminium core is available in 5 cell sizes the Compressive

seen from the data below.

MANUFACTURE OF ALUMINIUM HONEYCOMB PANELS
The expanded core is bonded to the outer facings with
a two pack adhesive, its properties allow it to "wick" on
to the core cell walls to ensure large area of contact.
The adhesive is applied on a dedicated computer controlled
spray booth facility, which allows close monitoring of coat
weights and accurate application to all substrates.
During this stage any inserts or conduits can be included
within the core to allow site fixing or wiring of ancillary
fittings to concealed points. Panels can have structural
frames incorporated in the same manner to agreed configuration.
The sandwich faces and core are laid up and accurately aligned
prior to transferring by means of roller table to the press.
The final bonding process is carried out in a heated hydraulically
controlled press to ensure uniformity of each panel. The
panel remains in the press during the adhesive curing process,
this is closely controlled taking account of press and ambient
temperatures to ensure reliability of bond.
After the curing process has been completed the panels are
removed from the press, inspected and stacked with appropriate
interleaving prior to transfer to Packing and Despatch area.
The Aluminium Hoenycomb panels will be wrapped and strapped
suitable for mechanical handling and where required crated
suitable for onward freighting. The specifications for the
protection and marking will be as agreed with individual
clients.
QUALITY
All operations will be carried out in accordance with an
ISO 9000 accredited quality scheme. We encourage client
visits, particularly during manufacture of their products;
likewise any client specified external inspection authority
is welcome for any individual contract. We will incorporate
Client specified checking procedures, in addition to our
in house monitoring, upon request, subject to mutual agreement
prior to execution of the order.
SPECIFICATION
Aluminium Honeycomb Panels core as detailed can be specified
in a large range of cell sizes generally the smaller the
size the higher panel strength with greater resistance to
impact. Core costs rise with cell size reduction and grade
of aluminium used from commercial grade to certificated
specifications. It is important to use the correct materials
to form the sandwich panels to achieve desired results at
economic cost.
Please consult
with us, we will be happy to advise and provide a range
of solutions with costs during initial stages, to tailor
the product to your individual requirements in an economic
and efficient manner. |
