Research by the Polymer Matrix Composites Group is looking at developing an automated machine to create fibre performs.
Automated spraying of carbon or glass fibre could soon provide the most economical way to create preforms in the manufacture of body panels for automobiles, heavy vehicles and other machinery.
Research headed by Bob Norris of the Polymer Matrix Composites Group in the US’s Oak Ridge National Laboratory's Metals and Ceramics are testing and advancing development of a programmable powdered preform process.
The robotically actuated machine sprays fibre and an adhesive powder binder substance to create fibre preforms. Resin is then injected in the mould and consolidated under pressure to create the final part.
The process is the first step in creating polymer composite structural and semi-structural auto panels that reduce the mass of composite automotive structures at a cost competitive with metal parts they are replacing. This results in lighter weight vehicles that are more energy efficient.
ORNL is working with the US auto industry and the Automotive Composites Consortium on this technology, which is funded by the Automotive Lightweighting Program in the US Department of Energy’s (DOE's) Office of Fuel Cell Technology.
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
The Brazilian composite sector expects to close 2018 with a turnover of US$ 685 million, a high of 3.8% compared to the previous year.
In late November, the 14 project partners in the MoPaHyb consortium developing a modular production plant for hybrid high-performance components wrapped up their successful efforts with a two-day symposium in Pfinztal, Germany.
