Rezumat:

The paper presents the assessment of the
interaction between microstructure and mechanical
characteristics for polyurethane materials used in
automotive industry for components production. Two types
of thermoset polyurethanes with the commercial name
Necuron 1020 and Necuron 1300 are investigated. The
paper present issues regarding the structure and
microstructural imperfections influence on the mechanical
properties related to operating conditions. Additives used
in the manufacturing process can affect the strength,
plasticity and toughness characteristics of the material,
causing in service failure of components. Paper shows how
pores and additives density affects the strength, plasticity
and toughness mechanical characteristics of analyzed
materials. In conclusions regardings these two materials
investigated, we showed the relation between structure and
mechanical properties.
