Ballistic composites – protecting the protectors
It seems scarcely credible that thin polymer fibers, bound together in resin, can stop projectiles ranging from a hand-gun bullet to a high-power rifle round, but they can and have done so, saving...
Composites in commercial jets
Boys and girls who decades ago assembled scale-model aeroplanes in plastic are today doing the same for real aircraft at full scale. With composites reaching proportions of up to 50% by weight in the...
Autoclave liberation gathers pace (part 2)
The search for viable alternatives to autoclaves has been underway for some time. George Marsh assesses where progress has reached and finds that some high profile projects are leading the way.
Reducing gearbox maintenance costs
Wind turbine gearbox failures can result in high repair costs plus lost revenue due to downtime. Even where there are no failures, gearboxes are likely to need overhaul at some stage.
All Energy 2012 preview: Big blades - the Blade Dynamics approach
The new-generation of wind turbines that will operate offshore require very large rotors. George Marsh looks at a different approach to blade design from Blade Dynamics – scaling down as opposed to...
