There are many kinds of materials used in making airplanes. Which one is not a common material for airplanes? A. aluminum B. wood C. gold D. composite materials 相关知识点: 试题来源: 解析 C。解析:飞机制造常用的材料有铝、复合材料等,有时也会用到木材,但黄金不是飞机制造的常用材料。
Fiber reinforced composite materials have been increasingly used as structural material in airplanes, in space applications, and in robot arms because of their high specific stiffness and strength. Structural design and nondestructive test techniques have evolved as increased emphasis has been placed on ...
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...
They work at the forefront of fibre technology & material science, turning our partners’ unique industry challenges into material possibilities. From advanced metal coated carbon fibre veils used in EMI shielding , to lightweight materials used in most airplanes today. ...
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...

Materials engineers also make the exotic ingredients necessary for quantum computers, and they produce the construction materials needed for various aerospace vehicles ranging from commercial airplanes to private space shuttles, Holm adds. When students ask her...
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...
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. ...
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 ...
