The article deals with of a hydrogen pressure vessel suitable for high pressure of approximately 75 MPa. One of the goals is to design a vessel from materials whose strength will meet mechanical requirements a calculated in both analytical and numerical ways. Another objective is the simulation of the design the pressure vessel with regard to safety and weight requirements.

In the paper there is the analysis of the possibility of the replacement of onerous methods of surface treatment before adhesive bonding. In ecology approach adhesive bonding is not preferred techniques of joying parts. The joints are no separable, but nonetheless have wide range of usage. The adhesive bonding has many assets, like low mass of the joining elements (less material), possibility of joint of different materials, lack of rivets or screws (less weight). But typical preparatory operations in adhesive bon...

At present the extraordinary and earlier unprecedented development of the industry is observed. The scale of the production of different goods is huge and concerns many areas on our planet.

Plastics are materials used in almost all areas of human activity and also in various branches of industry and in life in general. The growing production of plastics, their volume are evenly growing up also in the waste, therefore it is necessary to solve the plastic waste problem. The contribution deals with the using of recycled plastics plates and testing of sorted plastic waste. From the plastic waste as the semi-products re prepared for example the plastic plates by extruding technology, it means recycled pla...
