Abstract

The invention relates to a mechanical processing device and a method of ceramic-based complex curved surface parts with wave transmissivity. Most of parts of an aircraft are products with complex curved surfaces, the design and production cycle is long, and the processing workload accounts for more than 65% of that of the whole system; and a wave-transmitting radome has the characteristics of small dimension, compact structure and the like as a key part of a fairing of the aircraft, thereby affecting the flight performance of the aircraft. The device comprises a water storage tank (1), wherein a padding block (2) is arranged in the water storage tank, a workpiece (3) is mounted in the middle of the padding block, a fire poker (4) with a long circular hole is arranged on the padding block (2), the fire poker is fixed on the padding block by using a bolt (5) when pressing the processed workpiece, a water outlet (6) is formed below one side outside the water storage tank, and a water inlet (7) is formed above one side outside the water storage tank. The device is used for SiO2 fiber- toughened SiO2 ceramic-based composite materials, in particular to mechanical processing of the ceramic-based complex curved surface parts with the wave transmissivity.

Description

Technical field:

[0001] The invention relates to a technical field of mechanical processing; in particular to a SiO 2 A fiber-toughened ceramic matrix composite material is used as a mechanical processing device and a processing method for complex curved surface parts with wave-transmitting performance. Background technique:

[0002] In the field of aerospace, in order to improve the overall performance index of the aircraft and meet the requirements of high-speed, rapid and rapid response, some key components are mostly made of integral structures of high-temperature and oxidation-resistant materials. At the same time, most aircraft parts are products with complex curved surfaces, the design and production cycle is long, and the processing workload accounts for more than 65% of the entire system; Compact structure, etc. affect the flight performance of the aircraft.

[0003] SiO 2 Fiber-toughened SiO 2 Ceramic matrix composites are used as radome materials for their exc...
