On the development of experimental methods in research of folded core type z-crimp on the transverse compressive test strength

Abstract


This article reports the experience in conducting strength tests of folded cores reinforced composite materials. In order to increase the stability of the experimental results are given tips on how to test. Examples of types of fracture fillings such as z-crimp made of different materials are given.
