Polyamide 6Index. décimale : 668.4 Plastiques, vinyles Résumé : In large-scale automotive production, all-metal components are still mainly used instead of high-performance plastic/metal hybrids for reasons of cost. With a newly developed production process combining metal sheet forming and compression molding, hybrid components can now be manufactured more quickly and economically. Note de contenu : - Efficient production of hybrid components
- Tool technology and sealing concept
- Design of hybrid components
- Production of the longitudinal and transverse control arms
- Figure : The longitudinal control arm or a rear suspension system made from a hybrid comprising long fiber-reinforced PA6 and steel sheet is formed an dbonded in one step. The two materials combine lightweight design with fail-safe crash behavior
- Fig. 1 : The subsequent process oprations shown schematically in a sectio nthrough a hybrid compression mold
- Fig. 2 : To prevent escape of thermoplastic melt in hybrid compression molding, various sealing concepts were developed for the mold. Sealing profiles with open ends, such as for side or cross members, posed a particular challenge
- Fig. 3 : Comparison and results of different component variants based on cross-member geometry in the three-point bending test. Weighing 10 % less than conventional steel strike plate structures (black), the steel/LFT (orange) structure can withstand twice the load
- Fig. 4 : Thanks to the component-optimized design of the suspension link, a thinner metal sheet could be used in combination with the plastic, so achieving an overall weight saving of around 20% compared with the steel reference component
- Fig. 5 : View of the D-LFT machine that precedes hybrid forming and view into the hybrid mold at Weber Fibertech. One-step production of the steel/LFT longitudinal control arm follows in a hydraulic upper ram press

Terpolymère styrène anhydride maléïqueIndex. décimale : 668.9 Polymères Résumé : Telechelic poly(ethylene-ran-butylene) initiator terminated with [tert-butyl[1-(diethoxyphosphoryl)-2,2-dimethylpropyl]amino] nitroxide groups (PEB-(SG1)2) was used to initiate the controlled radical copolymerization of maleic anhydride (MA) and styrene (ST). The ST/MA copolymerizations were performed in 1,4-dioxane at 110 °C and resulted in PEB-b-P(ST-ran-MA)2triblock copolymers with relatively narrow molecular weight distributions (¯Mm/¯Mn≈ 1.5). Gel permeation chromatography (GPC) indicated that the initiator used was ≈ 93% efficient. The resulting copolymers were then blended as 20 wt.% dispersions in nylon 6 (PA6) at 230 °C. With as little as 10 mol.% of MA in the feed to make the PEB-b-P(ST-ran-MA)2, blends were deemed dynamically compatibilized based on the reduced particle size. All of the PEB-b-P(ST-ran-MA)2/PA6 blends resulted in a minor phase particle size ¯DVS = 0.1 μm while the PEB-b-P(ST)/PA6 blend had ¯DVS = 1.15 μm (i. e. no MA in the copolymer). Tensile testing revealed yield stresses and strains decreased steadily from pure PA6 to non-reactive PEB-b-P(ST)2/PA6 to PEB-b-P(STran-MA)2/PA6. However, no difference in tensile properties was observed between PEB-b-P(ST-ran-MA)2/PA6 samples made from PEB-b-P(ST-ran-MA)2copolymer of varying MA content.

ProductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : The worldwide market situation differs widely for PA6 and PA66. While demand and capacities for PA6 precursors and base polymers are balanced, supply shortages occur frequently for PA66, and in particular its precursor adiponitrile (ADN). This leads to partially drastic price increases. Therefore, a growing number of users is searching for PA66 alternatives. Note de contenu : - PA : Balanced capacities and demand
- PA66 : Structural supply problem and price hikes
- Globally increasing compounding capacity
- Growth market new mobility
- Contuining demand for blow-molded PA hollow parts
- Circular economy throughout the value chain
