nanotimes EU-Projects

The FR halogen-free compounds developed by the Nerefite project represent a significant step forward for the European textile industry. The new polymer materials can be used in the production of light- weight and hardwearing safety clothing for firefigh- ters and other hazardous occupations.

New Technology for Measuring Altitude

The goal of the Hastac project was to increase safety, particularly in conditions of low visibility, irrespective of the growth in air traffic. The consor- tium utilised on-board technologies that enabled aircraft to land in all weathers and prevented them from flying into the terrain. The project also deve- loped technologies for avoiding collisions while in flight and on the ground. The project enabled ma- nufacturers of altimeters, Air Data Computers (ADC) and auto pilot systems to develop more accurate and reliable systems for use in the latest aircraft and general aviation. New Micro-Electro-Mechanical Systems (MEMS) pressure sensors allowed aircraft to monitor altitude more accurately. The basic sili- con sensing structures could also be applied to other demanding applications in aerospace.

New Tools Cut the Cost of Aerospace Parts

The aerospace industry uses many alloys on account of the demand for materials that are tough, weldable and heat resistant. Two of these are A286 and INCO- NEL 718. Both are tough, malleable and corrosion- resistant. However they also share one major disad- vantage. Due to their high nickel content and heat resistance, they are difficult to machine resulting in high costs for the industry.

One solution is to change the composition of the mixture. Titanium/aluminium (Ti/Al) is one option as it has low density and high temperature resistance. However, this combination still presents the problem of low machinability.

With European funding to the tune of over EUR2 million, the project Machenera aimed to develop new machining tools, tool coatings and processes. In- stead of changing the material therefore, the cutting tools would be improved to increase their lifespan, gain a better overall finish and cut costs.

Machinera results cover a range of improvements. The design of cutting tools is superior in terms of geometry, and edge preparation. New nanocom- posite tool coatings have a high hardness rating combined with toughness and extremely high heat resistance, up to 1200° C (2192° F).
