The experiences on cellulose research in our region, first in Teltow and later in Potsdam-Golm, have extended over many years since the 1920s with the foundation of the Vereinigte Glanzstoff-Fabriken in Teltow-Seehof, followed by the Institut für Faserforschung and the Institut für Polymerforschung of the Academy of Sciences of the GDR, up to the Fraunhofer Institute for Applied Polymer Researc...

In this investigation an elastic stress analysis is carried out a woven steel fiber reinforced thermoplastic cantilever beam loaded uniformly at the upper surface. The composite beam material consists of low density polyethylene as a thermoplastic (LDFE, f.2.12) and woven steel fibers. Granules of the polyethylene are put into the moulds and they are heated up to 160°C by using electrical resis...

In this study, the heating capacity of nanocomposite materials enhanced with magnetic nanoparticles was investigated through induction heating. Thermoplastic (TP) matrices polypropylene (PP), thermoplastic polyurethane (TPU), polyamide (PA12), and polyetherketoneketone (PEKK) were compounded 2.5–10 wt.% iron oxide-based (MNPs) using a twin-screw extrusion system. Disk-shape specimens prepared b...

in this study, the effective factors on warpage in short fibre reinforced thermoplastic composites has been studied. first of all, the effective factors in manufacturing process were detected and then in order to decrease the number of experiments, the approach of design of experiments has been applied. by using micromechanics theory in composites and coefficients of thermal expansion models, a...

Combining photolithography and hot embossing offers the capability of cost-efficient and high-fidelity fabrication of polymer microfluidic devices, however, poor chemical resistance in nonpolar organic solvents and high gas permeability of the currently used polymers narrow the range of applications of the microfluidic devices. With the aim of specific chemical or biological applications, we re...

Previous research has demonstrated that production of natural fiber reinforced thermoplastic composites (NFRTCs) utilizing bacterially-derived pure polyhydroxybutyrate (PHB) does not yield a product that is cost competitive with synthetic plastic-based NFRTCs. Moreover, the commercial production of pure PHB is not without environmental impacts. To address these issues, we integrated unpurified ...
