Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
A programmable material that the Transformers are made from. Tritanium: Star Trek: The fictional metal tritanium was referred to in many episodes as an extremely hard alloy used in starship hulls and hand-held tools. Eve Online: A versatile material; the primary material used in the construction of virtually all star ships and star ship components.
In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. [1] Toughness is the strength with which the material opposes rupture. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing.
Both meta-aramid and para-aramid fiber can be used to make aramid paper. Aramid paper is used as electrical insulation materials and construction materials to make honeycomb core. Dupont made aramid paper during the 1960s, calling it Nomex paper. Yantai Metastar Special Paper introduced an aramid paper in 2007, which is called metastar paper ...
Worker placing a tire in a mold before vulcanization. Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur [1] or sulfur-containing compounds. [2]
The first woman was elected to lead a country 64 years ago. Here’s a look at where, and when, women have secured national leadership positions since then.
It is intended principally for heat resisting applications and also for uses where corrosion resistance and heat are required. Possible end uses are mufflers, furnaces, ovens, ranges, heaters, water heaters, fireplaces, and baking pans. Aluminized steel can withstand 550 °C (1,022 °F) with almost no change in the base material.
