Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Epoxy resin‐based composite materials were investigated. Samples were made of epoxy resin ED‐20 with the addition of different amounts of microspheres. Structure and sizes of small filler particles were determined. The derived compounds were tested for resistance to alternating temperatures and corrosive media. The results demonstrated that samples with the addition of 10 % of microspheres are more resistant to the impact of 25 % acid and alkali, as well as to gasoline. At the same time, the amount of the filler from 2 to 10 wt % does not influence the resistance to alternating temperatures significantly. The conducted tests demonstrated the resistance of the developed composite materials to alternating temperatures and corrosive media, which allows using them as corrosion‐resistant coatings for metal structures and in machine maintenance.
