Structural studies of fracture patterns in adhesive joints after pullout testing
- 17 Downloads
The adhesive strength of compounds based on epoxy resin ED-20 with the TEAT and PEPA hardeners is determined by pullout testing before and after administering shungite (20 wt %) as filler in their composition. The results of structural studies of the samples after the tests, which allowed determining the fracture type (adhesive or cohesive) and the number of samples that corresponds to each fracture type, are shown.
