The most recent and promising trends in development of renewable sources of energy are Combined Heat and Power (CHP) systems. The newest solutions from this field are hybrid compact solar panels. The correct operation of both systems, i.e. the photovoltaic panel and the heat exchanger requires an effective connection between the two. The adhesives utilized to interconnect above elements should provide a stable and hermetic joint able to withstand mechanical and thermal impacts of the surrounding environment factors. The paper presents the research results over the impact of the type and the amount of reinforcing phase on the physical and mechanical properties of epoxy resin matrix composites reinforced with particles of non-ferrous metals (Ag, Cu, W, Al), dedicated as adhesives for connections between photovoltaic panels and heat exchangers. Based on the experimental findings the usefulness of classical analytic models for valuation of polymer-metal composites properties was validated.

Purpose: Recent years have shown a dynamic development of underwater robotics. Autonomous biomimetic underwater vehicles (BUVs) with undulating propulsion are the latest branch in this area. They imitate not only the construction of underwater living organisms such as fish, but also kinematics of their motion. Such solution gives more energy efficient propulsion with less noise comparing to classical propulsion based on screw propellers [1]. However even the latest solutions still use the same electromagnetic engines to drive those sophisticated constructions. This article contains the concept of a ionic polymer-metal composites drive, design for undulating propulsion. Design/methodology/approach: Design of the new type of fin requires further tests and presented model takes under the consideration influence of only few factors described in this paper. Findings: Results of the research confirm theoretical behaviour of IPMC’s (Ionic Polymer- Metal Composites) and show some disadvantages of this type of materials. Research limitations/implications: The effects of the research are limited to macroscopic observation with limited accuracy. Practical implications: Results of the research show possible future application of IPMC’s (in underwater robotics). Originality/value: Results of this research opens a new idea which with further tests may result in developing a new quiet undulating propulsion for BUV’s.
