| Summary: | The article discusses the control of parameters of laser-perforated
metallized polymer films used in the manufacture of screenvacuum thermal insulation (SVTI) mats of spacecraft. The design,
operating principle and operating mode of the laser perforator
are described.
It is shown that the most important operational parameters of
perforated SVTI films are strength and dust release. Experimental
studies have shown that laser perforation leads to increased
strength and reduced dispersion for different samples of films
SVTI compared with similar indicators for manual mechanical or
semi-automatic thermomechanical perforation. When measuring
the profile of the edge of the perforated hole, the optimal
geometric parameters of the carbon Deposit zone consisting
mainly of carbon corresponding to the effective mode of laser
perforation and the maximum strength are determined. It is also
shown experimentally that laser perforation does not lead to an
increase in the dust release of SVTI films. |
