{{Short description|1934–1947 British adhesives company}} {{Use dmy dates|date=April 2022}} {{more citations needed|date=May 2011}} '''Aero Research Limited''' ('''ARL''') was a British company that pioneered several new [[adhesives]], intended initially for the [[aeronautics|aeronautical]] industry.
Formed in [[1934 in aviation|1934]] by [[Norman de Bruyne]] at [[Duxford]], [[Cambridgeshire]] from an earlier company of his, the Cambridgeshire Aeroplane Construction Company, ARL started a long-term relationship with the [[de Havilland]] company by initially working on reinforced [[phenol]]-[[formaldehyde]] resins for use in [[controllable pitch propeller|variable pitch]] [[propeller (aircraft)|propeller]]s. This material, being lighter than [[aluminium alloy]]s, offered much-reduced [[centrifugal force|centrifugal loads]] on the hub bearings.
This was followed by work on [[chemical synthesis|synthetic]] [[urea-formaldehyde]] adhesives and led to the [[Aerolite (adhesive)|Aerolite]] range of [[wood]] glues, used on the [[Airspeed Horsa|Horsa]] glider and the [[de Havilland Mosquito]] fast bomber and later, fighter.
ARL was responsible for developing a number of aeronautical-related adhesives, including [[Aerolite (adhesive)|Aerolite 306]], Aerodux 500, [[Redux (adhesive)|Redux]] - a metal-to-wood, metal-to-metal adhesive, used on the de Havilland [[de Havilland Hornet|Hornet]] and [[de Havilland Comet|Comet]], and the [[epoxy resin]] [[Araldite]]. Other products included its Aeroweb [[composite honeycomb|honeycomb]] core, and Fibrelam panels.
ARL was later sold to [[Novartis|Ciba]] in 1947 and its range of products later marketed under the Ciba (ARL) name.
