Influence of the Viscosity on the Degradation During Processing of PETG

, 2022
During processing, polymers are often subjected to high temperatures and high shear rates during the (long) residence times inside the machine. This can cause the material to degrade, leading to structural changes in the polymer chain and thus an overall change of material properties.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Analysis of the Elastic Behavior of Selected Types of Plastic Materials Used in 3D Printing

Macromolecular Symposia, EarlyView.
ABSTRACT This article analyzes the elastic behavior of 3D printed plastic materials, using FDM technology, to understand how they react to mechanical compressive stresses and to determine the limits of reversible deformation. In this research, a series of compression tests were performed on specimens made of five types of plastics: ABS (acrylonitrile ...
