According to the research data published by Boeing and Airbus, all their aircraft will use composite materials by 2020. At present, the amount of composite materials used on military aircraft has reached about 25 % of the structural weight, accounting for 80 % of the surface area of the aircraft.
The SMC used in the Yuanling bathroom is a kind of polymer composite material.
It is currently the most mainstream bathroom use material on the market, a true aerospace quality.

SMC is a kind of polymer composite material, which is widely used in six fields such as electronic power, aerospace, sports equipment, building reinforcement, pressure tube, and chemical preservation. Composites and metals, polymers, and ceramics are also known as the four major materials.
SMC appeared in the United States in 1932. Around 1963, it developed high-yield, wide-width, continuous production lines in the United States, France, Japan, and other countries, forming large-scale production, and began to be used in large quantities for sanitary Ware and automotive parts production. It is also an ideal material for aerospace vehicles such as aircraft, rockets, satellites, and spacecraft.

Solid motor covers produced by composite materials are resistant to corrosion, high temperature, radiation, and have low density, good rigidity, high strength, and stable size. Another example is the missile warhead Heweixing fairing, spacecraft heat-proof materials, and solar cell array substrates are made of composite materials.

The large-scale use of composite materials in aircraft structures is a revolutionary change in the history of modern aircraft manufacturing. It makes the aircraft lighter, stronger, more resistant to fatigue and corrosion, and the high-strength carbon fiber in the composite material can make the aircraft less expensive to manufacture after large-scale industrial production.
At the same time, with the support of advanced technology such as computer technology, laser, and C scan, the quality of the composite material manufacturing aircraft structure can ensure the safety of the aircraft more reliably. By 2020, Boeing and Airbus will have all their aircraft made of composite materials, according to published research.

So far, some applications have been achieved for the replacement of metallic spacecraft(satellites, space stations, space shuttles, etc.) with composite materials. The wide and successful application of composite materials in aerospace field shows that the composite materials have good properties and mature technology.

At present, the materials used in the overall bathroom on the market mainly include SMC, VCM, and Honeycomb materials, of which SMC is the mainstream.
SMC is an aerospace material that weighs less than one-fifth of a tile, but its strength is much better than that of a tile, and it will not crack, deform, or fall off. Light, tough, and durable are its advantages and have a service life of up to 30 years. At the same time, the standard of formaldehyde release of SMC materials has reached the E0 standard level, which is fully in line with the modern family's need for environmental protection.
SMC materials have a certain flexibility, and the overall sanitary overhead structure layer, waterproof chassis and the ground form an air layer, can effectively buffer the impact.
SMC material has thermal insulation performance, friendly skin. Winter insulation, summer insulation.
Japan is a large country that uses the whole bathroom. When the consumption of the whole bathroom raw materials produced by TOTO and Panasonic reaches more than 2,000 tons, it must establish a raw material production line to achieve the purpose of quality monitoring.
