Influence of Processing Technology on Mooney Viscosity and Burning Time of Mixed Rubber

Research and Application of Materials Science, 2019
The influence of mixed rubber processing technology on Mooney viscosity and burning time was studied. The results showed that the Mooney viscosity of mixed rubber increased with the extension of the parking time, and the burning time did not change significantly.

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

Advanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Bioinspired Metastable Transient Peeling for Repeatable Rapid Release

Advanced Science, EarlyView.
Inspired by the explosive seed ejection of the squirting cucumber, this work introduces metastable transient peeling that temporally regulates stored interfacial energy release via a tunable energy barrier. A viscoelastic hemispherical gripper achieves 52 ms ultrafast, residue‐free release with 300 000‐cycle durability, enabling damage‐free handling of

Structure and properties of high-content rubberized asphalt

Hecheng xiangjiao gongye, 2022
The content of ground tire rubber was limited by its multiple cross-linking networks. High-content ground tire rubber modified asphalt （mass fraction of ground tire rubber more than 30%） binder could be produced by addition of degraded tire rubbers （DR）,

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.
