ProductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : Polyolefin is versatile in application and exhibits a consistently high growth rate. The increasingly better understanding of the relationship between the structure and characteristics leads to new formulations. The essential sales markets continue to be the automobile industry, especially for PP reinforced with glass and carbon fibers, and packaging where the quality and recycling of PP are the dominating topics. Note de contenu : - Knowledge improves material
- PP reinforced with carbon fiber as a substitute for technical plastics
- Monolayers in demand for food grade strand-up pouches
- In the interest of sustainability
- Focus on non-intentionally added substances
- Recycling : specifications and measures are effective
- FIGURES : 1. Proportion of various polymer types out of total European consumption of 49 million t in 2015 - 2. Relationship between rigidity and impact resistance for Raheco and Soft PP types from Borealis - 3. Vehicle fender of a Magna concept study based on the Borealis development type Fibremod L10SY - 4. Two common versions of the structure of a laminated multi-layer film for stand-up pouches. left : standard structure, microwave safe with a view of the product (BOPET - biaxal oriented polyethylene terephthalate film, BOPA - biaxal oriented polyamide-6 film) - 5.

Moulage par transfert de résine sous videIndex. décimale : 668.4 Plastiques, vinyles Résumé : The trend toward electromobility only reinforced it : lightweight engineering has long been the focus of the automotive industry. Lightweight engineering has two positive effects on the sustainability of vehicles. A lighter vehicle consumes less energy for acceleration and frictional resistance. Moreover, fewer raw materials are needed for production which is another positive contribution toward sustainable mobility. Note de contenu : - Weight reduction with composite sandwich structures
- Weight and cost savings
- Established and cost-effective in large, global markets
- Example applications in series vehicles
- Sandwich manufacturing process
- The challenge of HP-RTM
- Short injection times allow the use of cost-effective rigid foams
- Process control based on the foam core's compressibility
- Optimum resin choice
- Successful test series
- Composite sandwiches are mature enough to significantly reduce a car's weight
- Fig. 1 : Different fibre reinforcements : oriented continuous fibres (tissue/scrim, UD) provide excellent mechanical properties (press process manufacturing
- Fig. 2 : Sandwich construction increases rigidity/stiffness at the same weight
- Fig. 3 : Increased core density over 0.1 kg/dm^3 hardly offers additional stiffness advantages
- Fig. 4 : With comparable stiffness and rigidity, the sandwich is much lighter, thus requiring fewer expensive raw materials. Thickness (height) is higher in the sandwich
- Fig. 5 : Pressure-time graph for a HP-RTM sandwich process showing the internal mould pressures, resin curing/viscosity at 100°C, and foam internal temperature
- Fig. 6 : Schematic curing behaviour of Loctite Max 2 at 70°C mold temperature

PolyuréthanesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Polyurethanes - Designs and multi-material elements incorporating rigid polyurethane foams have proven themselves in exterior applications, e. g. on façades, on the roofs of buildings, as solar module fasteners as well as on the exterior of automobiles and commercial vehicles. These positive results are now leading to consideration of this material for solar collectors. Note de contenu : - Resistant and lightweight
