This work focuses on the development of a numerical mold filling simulation for rotational molding process. In process, dry fiber preform is placed in and impregnated with thermoset matrix under rotation. Additionally, metallic load introduction elements can be inserted into joined co-curing or form-fit, resulting hybrid drive shafts tie rods. The model used to simulate impregnation preform. Ba...

AIM The aim of the study is to analyze the effect of different materials and techniques in current use on peripheral shaping of complete denture impression. METHODS The present study was conducted to compare and evaluate the maxillary border morphology produced using tissue conditioner as control and low fusing impression compound, Polyether, Pattern resin and periphery wax as border molding ...

In this study, the drop weight impact response and interlaminar shear strength of hybrid carbon/aramid fiber-reinforced laminated composites with different stacking sequences were investigated. Seven laminates including two types sandwich-like interply hybrid, three non-hybrid named carbon aramid produced using vacuum-assisted resin transfer molding method. Drop short-beam tests applied to calc...

Clinicians have been aware that posterior dental particulate-filled composites (PFCs) have many placement disadvantages and indeed fail clinically at an average rate faster than amalgam alloys. Secondary caries is most commonly identified as the chief failure mechanism for both dental PFCs and amalgam. In terms of a solution, fiber-reinforced composites (FRCs) above critical length (Lc) can pro...

Adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. On the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. The scope of this paper is experimental investigation on the effects of the addition of Alpha-alumina nanoparticles to the ...
