Problems solved by technology

In order to minimize the quality of the working medium carried by the micro thruster, the energetic working medium is an ideal ablation material. However, due to the lack of viscosity of single-base medicine, double-base medicine and other energetic working medium, polymer must be used after film formation. Imide, phenolic resin, etc. are used as adhesives to bond the drug film on the substrate. The adhesive acts as an intermediate layer to increase the thickness of the entire target tape, increase unnecessary weight, affect light transmittance, and reduce laser light. Energy utilization rate, and increase the manufacturing process, time-consuming, low efficiency

Abstract

The invention provides a self-adhesion laser micro-propelling transmission target ablation material. The self-adhesion laser micro-propelling transmission target ablation material comprises the following components in part by weight: 50 to 90 parts of energy supply material, 5 to 40 parts of improved bonding material and 5 to 15 parts of additive. The invention also provides a method for preparing the self-adhesion laser micro-propelling transmission target ablation material, and a target belt prepared by the ablation material. The ablation material has adhesiveness and contains an energy-containing working medium. The adhesiveness of a substrate of the ablation material can meet the using requirement and the utilization ratio of laser energy can meet the using requirement. The target does not use other bonding materials, avoids absorption of transmission laser by a bonding layer, reduces consumption of the laser energy and can effectively increase the utilization ratio of the laser energy. The ablation product is decomposed completely and the diffusion angle of the product is reduced. The ablation material saves the glue brushing process, simplifies the production flow, controls the thickness of the ablation layer easily and facilitates large-scale production.

Description

technical field [0001] The invention belongs to the technical field of laser propulsion, and in particular relates to a self-adhesive laser micro-propulsion transmission target ablation material, a preparation method thereof and a target belt prepared by the same. Background technique [0002] In 2000, C.R.Phipps of Photonics Associates proposed the concept of laser micro-propulsion, and successfully built the first pre-prototype for testing in 2002, which opened up a new direction for the development of laser propulsion. Laser micro-propulsion is to use the pulsed laser generated by the laser carried by the aircraft to ablate its own target material to generate high-temperature and high-pressure air masses to generate thrust, so as to achieve the purpose of attitude adjustment or orbit maintenance of micro-satellites. Compared with other micro-propulsion technologies, laser micro-propulsion technology has the advantages of light weight, high specific impulse, small impulse ...
