...carbon fibre reinforced plastic (CFRP) or glass fibre reinforced plastic. Sandwiches of CFRP are also used in many modern aircraft. Many of these materials are simply called laminates as they are indeed laminated together as each layer in built up and then cured with heat to precisely secure it into place.

...footprint. While not all bioplastics are biodegradable, they represent a more sustainable choice compared to traditional plastics, particularly in their use of renewable materials (Abe et al., 2021). The key to bioplastics’ potential lies in their ability to replace traditional plastics across a range of applications without compromising functionality. Whether it’s a...

...carbon dioxide. [Part of Nirgal Vallis, a valley on Mars first seen on this image by Mariner 9 in 1972. This image is 120km from side to side] Part of Nirgal Vallis, a valley on Mars first seen on this image by Mariner 9 in 1972. This image is 120km from side to side. In the 1970s attention turned to the much juicier topic of liquid water on Mars, with the discovery by...

...carbon-nitrogen water that is essential for life and these very early studies found that there was barely any volatiles present on the moon and that it was a born dry planetary body. However, in 2008, Saal et al published a paper looking at green glass which is produced in firefight interruptions to the moon surface and they found significant quantities of volatiles...

...carbon and alloy steels stainless steels aluminium alloys copper alloys titanium alloys nickel-based alloys With hot rolling it is easier to deform difficult-to-work metals than with cold rolling. Cast ingot structures, at heavy deformations and at temperatures where recrystallisation occurs, promote recrystallisation. Control of the sheet temperature can produce...

...carbon and low-alloy steels, stainless steels, aluminium alloys and brasses. Powder compacts can be orbitally forged to increase their densities to near theoretical. This is a type of powder forging. Design: Process is used to produce components with large-diameter flanges up to 150 mm dia. Components include bevel gears, claw clutch parts, wheel discs with hubs, bearing...
