Non-destructive Assessment of Relief Marking Parameters of Heat Shrinkable Installation Parts for Aviation Technology

P. 01004.
Kondratov A., Konovalova M., Cherkasov E., Savenkova I.

The article explains a new method of relief marking of heat-shrinkable tubing and sleeves made of polymer materials with "shape memory effect." Method of instrument evaluation of relief marking stereometry of installation parts for aviation equipment, made of polyvinyl chloride, polyethyleneterephthalate and polystyrene was developed and the results were explained. Parameters of pin-point relief marking and compliance of point forms to the Braille font standard were determined with the use of the non-destructive method based on the color of interference pattern with precision of 0.02 mm.
