The effect of pressure and temperature variations on the FEM prediction of deformation during extrusion [PDF]

, 2005
The extrusion process is complex, involving interaction between the process variables and the material’s high temperature properties and is typically conducted at relatively high temperatures because the lower flow stress of the material permits larger ...

Sericin as compatibilizer in starch/ polyester blown films

Polímeros, 2018
This study investigated the effects of low concentrations of sericin (≤ 1.5 wt%) in starch- poly(butylene-adipate-co-terephthalate) (PBAT) films. The films were produced by blown extrusion and mechanical, barrier and structural properties were determined.

PLA/PBAT blends for blown film extrusion

Polimery
Films of biodegradable PLA/PBAT blends with PBAT content of 10–90 wt% were obtained by extrusion blowing.  PLA/PBAT blends were characterized by FT-IR, DSC, TGA and SEM. Tensile properties and tear strength of the films were also determined. It was shown that despite thermodynamicimmiscibility of PLA and PBAT, addition of PBAT in amounts above 50 wt ...

Beyond Thin Film Limits—Superhard and Hydrogen‐Free Amorphous Carbon Coatings With Over 100 µm Thickness

Advanced Functional Materials, EarlyView.
For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Rheology of semi-solid fresh cement pastes and mortars in orifice extrusion [PDF]

, 2013
Short fiber-reinforced semi-solid fresh cement pastes and mortars, tailored for extrusion, have much lower water-to-binder ratio and higher viscosity than normal cement pastes or mortars. The rheology of these pastes or mortars cannot be characterized by
