Automotive Hybrid

Automotive Hybrid nonwovens from flax and PLA fibres Fig. 4: Hybrid nonwovens and isotropic bio-composites Fig 5: a) Mold designed for development of race car seat; b) Flax-PLA Nonwovens used to develop the composite; c) Molding process for development of composites; d) Form of the race car seat. a c Isotropic composites b d (Fig. 4). A fibre volume fraction of 40 volume % of flax was used (corresponding to 50 weight %). Bio-composite Demonstrator: Race Car Seat SLC-Lab collaborated with the Groep T University College of Leuven (Belgium) to develop a seat for a formula student racing car out of flax-PLA composite. The material properties of the fabric and composite were used to design the seat and the mould. Fig. 5 shows the mould as it was built and the form of the seat. Conclusions The project Nature Wins has shown that it is possible to produce 100 % biobased thermoplastic composites with minimal void content from intimately mixed textile preforms. The mechanical properties obtained of the nonwoven composites were comparable to those of glass fibre-PP or natural fibre-PP composites that are currently used in the automotive industry. Furthermore, a demonstrator was obtained in the project in the form a race car seat. Future work will include working closely with the automotive industry and its suppliers to benchmark the develop composite against the requirements of the automotive industry. Furthermore, additional of functionalities in the PLA fibres such as antiodour, fire retardence etc. is being looked in future collaborative projects.

Show preview After the successful move from Chicago to Orlando, NPE2015 will again be held at the Orange County Convention Center in Orlando, Florida, USA from March 23-27, 2015. Under the slogan “We invite you to make great things happen”, the Society of the Plastics Industry (SPI) invites to NPE2015: The International Plastics Showcase – brings together all sectors of the supply chain to include end markets and brand owners. Besides machinery, auxiliaries and conventional plastics NPE will again be a showcase and technology exchange for polymers derived from renewable resources such as corn, castor beans, soybeans, potatoes, tapioca, and many more. Again bioplastics will be one of the most interesting topics in this year’s NPE. bioplastics MAGAZINE will not only be an exhibitor (please come and see us at booth S20192, South Hall Level 1) but also offers on the following pages a comprehensive show preview (including a floor plan as a take-out centerfold) and a show review in issues 02 and 03/2015. On our website you will find more bioplastics related info as we approach the show … MHG (Meredian, DaniMer) Biopolymer manufacturer, MHG, formerly known as DaniMer Scientific and Meredian Inc., will be exhibiting their 100 % biodegradable plastic at their exhibit location S35027. During NPE, the company will showcase their mcl- PHA (medium chain length polyhydroxyalkanoates) and their process of converting non-GMO canola into plastic pellets that make many different plastic products. The PHA that MHG produces is completely biodegradable within 12 – 18 weeks and is Vinçotte certified in all six different mediums. The company will also be showcasing the PLA that is produced at their facility. They are currently using the most advanced proprietary reactive extrusion process on the market. Other products that can be created with the PLA include injection molding, thermoforming, extrusion lamination, film resins, additives, hot melt adhesives and wax replacement polymers. While there are many products that can be made solely from MHG’s PHA, the company can customize their formulations and combine both the PHA and PLA to cater to their customer’s needs. RheTech RheTech, Inc. (Whitmore Lakes, Michigan, USA) will be showcasing its RheVision ® line of bio-reinforced polyolefins that takes true bio waste products and, with its proprietary production line, provides a compound that is the leading edge of environmentally-friendly technology. RheVision currently uses coconut shell, flax, hemp, paper powder, rice hull, and wood waste as reinforcement. RheVision can replace traditional minerals and fiberglass that take energy to mine/produce and have a finite supply, with renewable bio waste. All of RheTech’s bio fibers are true waste products that are either traditionally burned or buried. These products come from a variety of sources, but none are grown for the specific purpose of being added to our plastic. By using RheVision, customers can reduce their carbon footprint and dependence on high energy consumers, like fiberglass and talc. The RheVision line has drawn a great deal of attention as companies look for low-environmental-impact solutions to component product development. RheVision also offers grades that contain true postconsumer content. The company can incorporate up to 15 % of a certifiable post-consumer polyolefin resin. This allows RheTech to provide a product that could contain over 50 % waste product. S35027 S15119 bioplastics MAGAZINE [01/15] Vol. 10 23
