Separation of Multi-Material Polymer Combinations Produced by Joining Using Pin-like Structures

چکیده
In industrial applications, multi-material joints are becoming increasingly important to achieve a sustainable and resource-saving production. Not only high mechanical properties during the component use have be given, but also possibilities separate joint after end of life crucial. The recycling re-use materials plays an increasing role in process chain. Conventional can separated by cutting out joining zone, solvents, or thermal degradation. However, these methods result loss material, damage base energy consumption. Therefore, novel desirable, such as using pin-like structures. potential this method for adhesion incompatible has been demonstrated previous studies. This paper studies separability connections. between polyamide 66 (PA66) polypropylene (PP) well PA66 polymethylmethacrylate (PMMA) investigated means separation shredding with subsequent sorting density difference materials. components were analytical (including dissolution tests, viscosity number analysis, Fourier-transform infrared spectroscopy) respect varietal purity possible degradation effects. It could shown that allows complete into its individual without material residues loss. For separation, PP PMMA detected pin gaps PA66. both methods, influence on due effects excluded. stated structures vibration welding technology offers production recyclability.

Phase separation induced by ladder-like polymer-polymer complexation.
Polymer-polymer complexation in solvent is studied using an extension of the self-consistent field theory. The model polymers are capable of forming ladder-like duplex structures. The duplex formation occurs with an abrupt change of entropy, resulting in a first-order transition. Moreover, the complexation can be stabilized by solvent-polymer interactions, instead of the usual specific binding ...

Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures are often close to material structures (i.e., material lines or material surfaces). Moreover, it has been proven that for an integration time converging to infinity, they con...
