Epoxy resins are widely used as matrix materials for the fabrication of advanced composites in electrical and electronic industry as well as in structural laminates used in airplanes and motor vehicle construction. These fiber-reinforced composite materials offer advantages such as lower weight, improved...
Some materials have long been used to build automobiles, but some new ones are also gaining ground in the industry. See more diesel engine pictures. ©iStockphoto.com/Ricardo Azoury Have you ever wondered exactly what your car is made of? No, not how hard and fast it can be pushed...
in terms of specific rigidity. Aluminum alloys are used in the manufacture of frames of airplanes, helicopters, rockets, and ships of various types. Magnesium alloys have high specific volume (four times greater than that of steel); their strength is 400 MN/m2and higher. They are used ...
Inconel is an alloy made of chrome and nickel. Because of its extreme heat resistance, it’s often used to make the black boxes in airplanes and parts for rocket engines. It requires direct metal laser sintering technology, otherwise the metal is difficult to work with. ...
Metallic materials are ubiquitously used in hypersonic vehicles – as nose and wing leading edges, control surfaces, and engine inlets – due to their tendency to their damage tolerance and manufacturability. These components need to withstand extremely high heat fluxes and thermal strains, which deman...
From airplanes in the sky, to a dental filing, to home roofing, bathroom and kitchen materials – heat resistance and appealing aesthetics are nonnegotiable. With over 100 years of experience, Vibrantz offers optimal solutions for end-use markets like automotive and transportation, construction, ...
MIT envisions the material potentially being used in automobiles, airplanes, and other applications where weight needs to be as low as possible, but strength and rigidity is still of great importance. The new graphene-based 3D material is thought to be one of the strongest, yet lightest materi...
The social issues are manifold and include the increasing global interdependence of business, the unprecedented political revolutions in every part of the world, and the universal human desire for travel. In addition, concerns have grown about the environmental impact of airplanes, especially in regards...
Leverage industry-leading molecular simulation and machine learning to guide in silico design of novel materials for more lightweight and efficient airplanes and spacecraft. High-performance sealants and seals Develop sealants faster with molecular simulations for high-temperature applications in aerospace....
