Proven technology of bulk electrophoretic coating (2019)

he main task, respectively the goal of the 2019 project of mass cataphoresis painting of small parts was to verify a completely new technology of mass painting. Based on the achieved partial results and experience from previous years, especially from painting with the prototype device for mass painting with charge in units of kilograms of parts per hour, the procedure of optimization and verification of mass EC painting technology was determined. A series of stress tests has been established and launched to verify the functionality of the entire comprehensive EC bulk coating technology. Special cathodes with surface treatment have been developed to eliminate the coating of the surface itself, ie loss of charge transfer capability. Furthermore, a continuous chamber oven with a special wire conveyor was designed and optimized to eliminate defects in the polymerization of parts. The functionality of bulk EC coating using a drum with special treatment of cathodes and polymerization in a chamber oven has been verified by a series of operational tests.

This project result was developed within TH02020019 project  "Development of new technology for mass coating by electrophoretic coating systems" with financial support from TA ČR.

Semi-preparative technology for electrochemical deposition of high entropy alloy coatings (2017)

Description of the high entropy alloy coating (HEA) semi-preparative technology: light modification of the galvanic water bath laboratory tested earlier, change of power source, rinse technology and pretreatment of samples. In the case of baths, the concentrations and types of metal salts used were slightly different, as well as the addition of surfactant. The DC power source has been changed to a two-pole and more powerful, instead of a rather measuring device VoltaLab . A new degreasing bath and an activation bath were prepared. Optimization was focused on the possibility of coating larger samples without the need to brush their surface before applying the coating.

This project result was developed within the institutional support of the Ministry of Industry and Trade of the Czech Republic directed to the development of research organizations.

Epoxy foam for composite sandwich structures (2017)

The aim of this project was the replacement of old inconvenient foam system used for preparation of composite sandwich structures. For this purpose, a new epoxy foam system was developed with the use of epoxy resin MGS LR 385, hardener MGS LH385, foaming agent Wacker Crosslinker W and surfactant Tween 80. This composition was used for production of foam core of fan blade. Density of this foam core was 0.195 g/cm3 and foam had homogeneous structure. Pot life of mixture of reactants was 30-60min and complex storage modulus had value of 90 MPa.

This project result was developed within the institutional support of the Ministry of Industry and Trade of the Czech Republic directed to the development of research organizations.

Geopolymeric foam for sandwich structures (2017)

The aim of this project was the development of foam plate made of anorganic polymer. The solution was based on metakaolin geopolymeric resin. Foaming effect was created by hollow thermoplastic microspheres filled with liquid hydrocarbon, which is expanding under elevated temperature. Homogeneous geopolymeric foam plate with thickness 10 mm, dimensions 24 x 34 cm and density 0.23-0.61 g/cm3 was developed. Another foaming agent - hydrogen peroxide was also tested.

This project result was developed within the institutional support of the Ministry of Industry and Trade of the Czech Republic directed to the development of research organizations.

Manufacturing process of composite parts of engine cowlings (2015)

Proven manufacturing process for composite parts of engine cowlings of aeroplane L-410NG by Resin Film Infusion (RFI) method. Composite parts of the engine cowlings are classified as secondary aircraft structure with increased requirements for temperature resistance. RFI method is infusion manufacturing process. The method is based on impregnation of dry reinforcement by film resin. A composite part lay-up consists of several plies of dry reinforcement and film resin. Curing of the lay-up is performed at elevated temperature when the resin becomes liquid and impregnate adjacent dry reinforcement.

This project result was developed within the project FR-TI4/543 "Project INKOM - Integration of Composite Materials into Airframe of Small Transport Aircraft (2012-2015, MPO/FR)" of the TIP program of the Ministry of Industry and Trade of the Czech Republic.
