Ogljikove nanocevke zaradi inherentnih lastnosti predstavljajo superiorna funkcionalna polnila v polimernih nanokompozitih, saj omogočajo odlično mehansko ojačitev, električno prevodnost in druge podobne lastnosti. Rezultati doktorskega dela so pokazali, da se ogljikove nanocevke med predelavo razpl ...

Uporaba kompozitnih materialov v industriji, še posebej v navtični, je zelo pogosta. Kupci na proizvajalce pritiskajo z zahtevo po čim cenejših izdelkih, ki so obenem tudi v skladu z ekološkimi smernicami. Proizvajalci morajo tem zahtevam slediti, obenem pa poskrbeti še za to, da so izdelki mehansko ...

Linear viscoelastic range (LVR) of bread dough with various composites was determined with oscillatory amplitude tests, while frequecy test (performed in LVR) enabled determination of viscoelastic behaviour at small deformation. In order to determine flow characteristics of the dough and to evaluate ...

Mechanical performance of SFRP depends on various factors (fiber fraction, geometry, etc.), among which the fiber orientation is difficult to predetermine, yet it needs to be considered during product design and manufacturing. This is important for parts with complex geometry and varying wall thickn ...

The reinforcing and conductive performance of carbon nanotube polymer-based nanocomposites depends on the established network and its configuration. Within this study, we report on the underlying mechanisms of such network formation utilizing single-walled carbon nanotubes (SWCNTs) in low- and high- ...

To decrease the amount of plastic waste, the use of recycling techniques become a necessity. However, numerous recycling cycles result in the mechanical, thermal, and chemical degradation of the polymer, which leads to an inefficient use of recycled polymers for the production of plastic products. I ...

The mesh formation of single-walled carbon nanotube (SWCNT) superstructure, i.e. nano-mesh, in low- and high-density polyethylene (LDPE and HDPE) matrices was observed by using plasma etching technique and SEM analysis. Nano-mesh was established by two mechanisms: i) alignment of SWCNT bundles (form ...

Polyisobutylene (PIB) is commonly used as a primary sealant in multi-layer insulating glazing elements, where temperatures often exceed 100 °C. At such conditions, PIB undergoes structural changes, causing different relaxation dynamics and leading to decreased lifetime of the material. Understanding ...
