Old materials in a new design

Researchers present useful ideas for 3D printing

08-Oct-2019

Plastic could soon be saying goodbye to its bad reputation. A working group headed by Professor Rolf Mülhaupt at the Freiburg Materialforschungszentrum (FMF) is currently developing “single-polymer composites” that can be produced from both fossil and renewable raw materials and later recycled ...

Intelligent material improves aerodynamics in cars and aircraft

Start-up designs active components and systems based on shape memory alloys

22-Mar-2019

In order to save energy, aerodynamics is important for cars and aircraft. However, technologies controlling saving of energy are only designed for one speed range. Researchers at Technische Universität Kaiserslautern have developed a more flexible method: Thanks to a so-called shape memory wire, ...

Laser-induced graphene gets tough, with help

Combining conductive foam with other materials for capable new composites

15-Feb-2019

Laser-induced graphene (LIG), a flaky foam of the atom-thick carbon, has many interesting properties on its own but gains new powers as part of a composite. The labs of Rice University chemist James Tour and Christopher Arnusch, a professor at Ben-Gurion University of the Negev in Israel, ...

Multifunctional dream ceramic matrix composites are born!

Ceramic matrix composites exhibit electrical conductivity and photocatalytic activity

07-Dec-2018

Researchers at Osaka University produced composites consisting of alumina (AI2O3) ceramics and titanium (Ti), namely AI2O3/Ti composites. They designed a percolation structure for forming a continuous conduction pathway by dispersing fine-sized Ti particles into an AI2O3 matrix, optimizing the ...
