Araldite epoxy systems used in model aircraft

A Huntsman Advanced Materials product story
Edited by the Engineeringtalk editorial team Jun 17, 2009

Araldite epoxy systems supplied by Huntsman Advanced Materials are being used by two model aircraft enthusiasts hoping to influence the design and aerodynamic performance of future model aircraft.

Ronny Janssen and Patrick Sloot from the Netherlands hope the development work they are doing on their own scale model jet plane could radically influence the future design and aerodynamic performance of many other remote-control model jet aircraft.

The Jetco model is a radio-controlled twin-boom jet plane weighing 9kg, with a 1.55m wingspan, and powered by a gas-turbine engine.

Araldite LY 3297/Aradur 3298/Aradur 3299 epoxy composite system has been used to build the wings, elevator and some structural parts of the fuselage.

The jet's wings are made from an EPS foam core covered with a sheet of balsa wood.

However, to be able to withstand the dynamic loads of up to 40G reached during flight, the wings are reinforced with an 80g/m2 woven glass fibre fabric, impregnated using the wet lay-up method with the Araldite epoxy resin system.

Araldite LY 3297/Aradur 3298/Aradur 3299 is a cold-curing epoxy system suitable for the production of a range of industrial components.

The reactivity of this low-viscosity, highly flexible system can easily be altered by varying the combination of hardeners.

It can be processed using wet lay-up, resin transfer moulding or pressure moulding production technologies.
