A study of the fracture, mechanical behaviour and morphology of an epoxy resin system

The fracture and mechanical properties of an epoxy resin system have been investigated as a function of changes in stoichiometry and heat treatment. Relationships between the various macroscopically measured properties and the microscopic characteristics of the cured resin are described. The investigation shows that the concept of fracture surface work, Ƴ , measured by a cleavage technique, is a sensitive parameter for monitoring changes in the resin's fracture properties and that the Irwin-Kies and Berry analyses can provide a more sensitive monitor of Ƴ than the Gurney method, in some circumstances. The investigation also demonstrates how the elastic and visco-elastic properties of the resin can effect plasticisation at the tip of a crack, with consequent improvement in fracture toughness. To aid the interpretation of the mechanical data, a morphological characterisation of the cured resin will be described in which quantitative infrared spectroscopy, thermo-mechanical analysis, solvent. uptake resistance, chemical and ion-beam etching methods have been used

Objectives: The clinical and social burden of the COVID-19 pandemic were high among asylum seekers (ASs). We aimed to understand better ASs’ experiences of the pandemic and their sources of worries.Methods: Participants (n = 203) completed a survey about their worries, sleep disorders, and fear of dying. We also conducted semi-structured interviews with ASs living in a community center (n = 15), focusing on how social and living conditions affected their experiences and worries.Results: ASs in community centers experienced more sleep disorders related to the COVID-19 pandemic than those living in private apartments (aOR 2.01, p = 0.045). Similarly, those with lower education had greater fear for their life due to the COVID-19 pandemic (aOR 2.31, p = 0.015). Qualitative findings showed that sharing living spaces was an important source of worries for ASs and that protective measures were perceived to increase social isolation.Conclusion: Our study highlighted the impact of the COVID-19 pandemic for ASs and the importance of tailoring public health measures to their needs and living conditions.</p
