Recycling
Various topics related to sustainability in plastics, including bio-related, environmental issues, green, recycling, renewal, re-use and sustainability.
New life for aircraft waste composites
Recyclable thermoplastic composite materials, made of waste from dismantled aircraft and polystyrene loose-fill packaging, are capable of handling high weight loads.
Wood apple shell particulates reinforce epoxy composites
Adding biodegradable shell particulates to an epoxy resin matrix yields superior thermal stability and mechanical properties while lowering fabrication cost.
Strengthening composites with waste rubber
Process optimization enables impact modification of polymer composites using surface-coated waste rubber particles.
Poly(butylene succinate)/ halloysite nanotube nanocomposites
The strength and modulus of poly(butylene succinate) can be increased with the addition of halloysite nanotubes, without a significant loss of ductility.
Effect of nanofiller type on degradation of polylactic acid
Polylactic acid nanocomposites with montmorillonite and silica nanofillers showed different thermomechanical property alterations over a six-month aging period.
Biobased and biodegradable polylactide composites with waste cotton fibers
Blending polylactide with other polymers, fibers, and fillers leads to novel materials with modified properties.
Chitosan/titanium oxide composite: a photocatalyst and bacteriocide
A chitosan/titanium oxide composite exhibited high photocatalytic activity against harmful dyes as well as antibacterial properties, and it was easier to recover from the environment than titanium oxide alone.
Characterization of kaolin-filled polymer composites
Addition of a treated kaolin filler improves the mechanical and electrical properties of polymer composites produced from unsaturated polyester derived from polyethylene terephthalate waste.
Biocomposites based on poly(lactic acid) and hydrotalcite
The benefit of adding a filler may be outweighed by matrix degradation.
Transforming the resource base: new bioplastics
Poly(lactic acid) combined with nylon-11, a polymer from castor oil, creates a new family of 100 renewable plastic materials.
Wheat-gluten biocomposite films reinforced with rice husk
Adding a chitosan-polyethylene glycol plasticizer and a rice-husk filler to wheat-gluten films improves tensile strength and modulus, hardness, and water resistance.
Tough, biodegradable poly(L-lactic acid) polymer blends
Blending poly(L-lactic acid) and polyhydroxybutyrate, with tributyl citrate as the plasticizer, increases molecular mobility and the rate of crystallization.
Adhesive Technology for Automotive Multi-Material Substrate Bonding
The global trend towards improved fuel efficiency and reduced environmental impact is driving the use of new and dissimilar substrates for lightweight vehicle construction. Modern lightweight designs require new joining technologies to support the use of new materials as well as an increased use of mixed material substrates. Adhesive bonding is an enabler for lightweight and mixed substrate construction — allowing joining where traditional methods are not feasible — and takes advantage of structural bonding benefits such as improved load bearing capability enhanced NVH performance ride and handling and safety. This presentation will focus on the available adhesive-bonding solutions and will give an outlook into future adhesive-development directions.
Alternative Precursors for Sustainable and Cost-Effective Carbon Fibers usable within the Automotive Industry
Lightweight design is an essential part of the overall Volkswagen strategy for reducing the CO2 emissions. Carbon fiber-reinforced polymers (CFRP) offers an enormous lightweight potential. The use of CFRP is limited in mass series applications by the costs of the conventional C-fiber precursor Poly-Acrylic-Nitrile (PAN). The investigation of novel alternative precursors enabling a significant reduction in the costs of CFRP automotive parts is essential to make carbon fibers ready for a mainstream use within the automotive industry
Commercial Applications of Bio-Based Polymers in Automotive
PowerPoint Presentation at Automotive Composites Conference and Exhibition
Automotive Sunroof Systems & Frames in Xiran® SMA/ABS
Automotive sunroof systems which have become a must-have for the added comfort and styling to today's cars increasingly rely on engingeering plastics functionalities to replace mtals. Structural and semi-structural sunroof module components sunroof frames in particular typically need to meet a wide range of technical requirements with a clear focus on the integration of functions safety cost and weight reduction. The glass-reinforced materials thermoplastics and thermosets currently used for sunroof frames are mostly based on PBT/ASA PBT PA PP and unsaturated polyester SMC. These products are not a perfect match for the application needs of today and the future. Glass-reinforced SMA/ABS on the other hand offers an ideal unique combination of properties required in sunroof frames and systems. SMA/ABS-GF compounds such as Polyscope's Xiran SG grades have clear technical and commercial benefits such as; high dimensional stability and precision very large warpage compliance to mold cavity shape good performance at low wall thickness high creep resistance excellent adhesion without surface treatment low density high economic value good chemical resistance and easy recylability with efficient waste streams.
Eco-Friendly Automotive Plastic Seat Design
This paper deals with plastic front and rear seat designs that provide more than 20% weight reduction for improved fuel efficiency and lower CO2 emissions. The materials of construction include recyclable plastics and “green” polyurethane foam making this design eco-friendly. Low cycle time reduced part count and assembly time optimized contours for passenger comfort and reduced material consumption lead to cost-competitive design.
Fire Resistance Cellulosic Fiber-Thermoset Composites
This presentation reports an innovative and sustainable approach to fiber surface treatment that improves the fire resistance of cellulosic fiber/ epoxy composites made with flax fiber. This new approach not only retards burning of cellulosic fiber but also produces self-extinguishing cellulosic-fiber composites. The low-cost treatment was carried out in aqueous solutions using non-toxic inorganic chemicals
Carbon Fiber Reinforced Composite Waste: An Environmental Assessment of Recycling Energy Recovery & Landfilling
The environmental benefits of recycling carbon fiber- reinforced plastic (CFRP) waste are assessed against other end-of-life (EOL) treatments. Recycling via pyrolysis incineration with energy recovery and disposal via landfilling are compared. To account for physical changes to materials from use and recycling equivalence between recycled and virgin materials is calculated based on the ability to produce a short-fiber composite beam of equivalent stiffness. Secondary effects of using cecycled carbon fiber (RCF) in a hypothetical automotive application are also analyzed. Results underline the ecological constraints towards recycling CFRPs and demonstrate that benefits from recycling are strongly linked to the impacts of the selected recovery process the materials replaced by RCF in a secondary application and also to the type of secondary application in which they are used.
Compaction Behaviour and Permeability of Cellulosic Fibre for RTM Applications
With the current driving force to use more sustainable and/or recyclable materials the automotive market is considering cellulosic fibres and biocomposites with a growing interest. However for those fibres to be used efficiently in thermoset liquid processes such as resin transfer molding (RTM) reinforcement compaction response and permeability must be well-known as they govern resin flow injection time and void formation and therefore are key to success. In this presentation the compaction response and permeability of flax and hemp mats were investigated and compared to traditional glass fibers.
