Background

With the rapid development of the world civil aviation industry, the number of the flight taking-off and landing frames is obviously increased, the number of the airplane rushing out of the runway is in an ascending trend, and how to avoid serious accidents after the airplane rushes out of the runway becomes an important subject of civil aviation safety. It is known that the rushing out of a runway by an aircraft is one of the more harmful problems in an aviation accident. Relevant studies have shown that, in the event of an accident sign that seriously jeopardizes civil aviation flight safety, the aircraft rushes out of the first of the runway space. By laying a characteristic Material Arresting System (EMAS for short) at the end of the runway, the safety guarantee equivalent to the new standard can be realized without increasing the length of the safety area.

The EMAS is a crumple energy-absorbing material with specific mechanical property, is laid on the ground of a runway extension line in the thickness of tens of centimeters, has the width consistent with that of the runway and the length of tens of meters to 150 meters, and can form a barrage bed. Once the aircraft enters the arresting bed, the foam body is broken under the wheel rolling pressure, so that the kinetic energy of the aircraft is absorbed, and the aircraft can be arrested in the arresting bed. For some airports with complex terrains, dangerous terrains such as steep ridges, deep ditches, water surfaces, roads, obstacles and the like exist outside the safe area at the end of the runway, which is equivalent to prolonging the length of the safe area at the end of the runway. Therefore, it is very practical and more economical to install the EMAS in the safe zone outside the runway end.

At present, EMAS mainly uses foamed concrete, but the foamed concrete has the defects of large open pore ratio, strong water absorption and the like, and the foamed silicone rubber prepared by chemical foaming for rapid in-situ foaming molding can ideally solve the problem. The material can generate cross-linking and foaming reaction in a short time in the forming process, and is quickly cured and formed in a device; meanwhile, a large amount of heat can be released from the material in the reaction process, and the material is easy to adhere to a forming device, so that the forming device is required to have good heat dissipation performance and anti-adhesion performance.
