These are the most innovative auto parts

the automotive branch of the American Society of plastic Engineers (SPE) announced the classified winners of its 46th Automotive Innovation Grand Prix in November. The Grand Prix is the oldest and largest recognition event in the automotive and plastics industry. Let's see what award-winning works are there

carbon fiber composite deflector

figure 01

the carbon fiber composite deflector (Figure 01) used in general motors (GM) 2016 Chevrolet Corvette sports car won the award of auto parts category. This product adopts mtm5790 epoxy resin of Solvay company. This one-piece epoxy/carbon fiber deflector accessory has an advanced carbon composite appearance, and has the same aerodynamic performance as the three-piece deflector with different aerodynamic components, while reducing the weight by 40%

the deflector adopts a unique design and proprietary mold, which combines open cavity blades and integral threaded inserts, making it easy to manufacture and assemble. The overall structure has a cleaner appearance due to the reduction of fixed parts. The deflector has the type of transparent coating with exposed texture and the type of carbon flash metallic paint spraying

the structural front-end module of the active air intake grille of Ford Super Duty Truck 2016 (Figure 02) won the award of body exterior decoration category

this product adopts celtran black long fiber reinforced thermoplastic (LFT) polypropylene (PP) and is produced by injection molding process. This all composite design without metal reinforcement is the first application of injection molded lft-pp front-end module supporting the function of active air grille (AGS) on heavy trucks

this design replaces the steel and plastic/metal composite structure. Each vehicle can reduce the weight by 1.4 kg, save 3 dollars, integrate the parts together, have the positioning function, facilitate assembly and surface treatment, improve the airflow, and meet the structural requirements of 1mm deformation of parts on this 3856 kg traditional vehicle

perfect posture seat suspension system

figure 03

this composite suspension for the upper and lower backrest of Ford 2017 Lincoln Continental limousine (Figure 03) won the award in the body interior category

it adopts Ultramid b3zg7 OSI Pa; Ultramid B3EG3 PA; ADX 5017 TPO and Delrin 100 Polyoxymethylene (POM) are manufactured by the stacking process. Due to the overall composite design, this "perfect posture seat" suspension system can fine tune the suspension, and improve the comfort of passengers by suspending the upper backrest and providing body side support (which can be bent to adapt to various physiques). The allocation period is 10 years; The special accessories placed after the second phase of the project is put into operation are convenient for assembly and shorten the maintenance time

the design also forms a robust dynamic crash energy management system for rear crash protection. The direct injection molding coloring process is adopted to realize the exquisite workmanship of class a surface. The system has 83 patents. Although more functional parts are added, the weight of the seat is reduced by 8% and the cost is reduced by 15%

shock mount with weight reduction of 30%

shock mount of GM 2016 Cadillac CT6 luxury car (Figure 04) won the award in chassis/hardware category. The product adopts BASF's Ultramid a3wg10cr 50% glass fiber (GR) reinforced PA 6/6 and is produced by injection molding process. This is the first time to use glass to measure the stress change on the sample. It is also the first time to use polyamide shells on the front and rear suspension systems

this injection molded part integrates the common components of the front and rear supports, adopts a special thread assembly method, and has a locking function. Compared with typical steel and aluminum components, they reduce the weight by 30% and reduce the noise transmitted through the suspension system. Due to the modular assembly, the design has greater adjustment flexibility

closed loop bottle made of pet water bottle recycling

the closed loop bottle (Figure 05) recycling product adopted by GM 2016 Chevrolet equinox and GMC Terrain crossover multi-function vehicle (CUV) won the environmental protection category award. It features non-woven brushed fabrics made from recycled polyethylene terephthalate (PET)

this innovative, multi stakeholder, cost-free project can protect the environment, promote local economic growth, create jobs, and help people in a sustainable way. The water bottles collected from GM factory and flint area, Michigan, USA directly enter a supply chain with relatively loose internal structure. In this supply chain, the recycled materials are processed into non-woven brushed fabrics for a variety of applications, such as engine manifold cover thermal insulation materials, jacket thermal insulation materials (converted into homeless sleeping bags, which were previously made by homeless women as part of the work plan), As well as the air filter used in many GM production plants and other manufacturing plants to purify the air that will check the authority of the operator. 350000 water bottles have been recycled

vacuum brake pipe with weight reduction of 30%

figure 06

the vacuum brake pipe of GM 2016 Chevrolet Silverado and GMC Sierra trucks (Figure 06) won the material category award. The product adopts DSM arnitel cm622 thermoplastic polyester elastomer (tpc-et). Vacuum brake pipes need a high-performance thermoplastic material to replace reinforced rubber. The material is required to have a wide working temperature range (-? C), good chemical resistance, minimum bursting strength of 60 bar and minimum bending strength of 50 n. Also required at 150? C. Vacuum collapse resistance under 2H condition, 150? Maintain the impact strength after 336h at C

the design is changed to adopt smaller diameter and thinner wall, so as to simplify the laying of pipelines in the engine/chassis, eliminate the phenomenon of heat shielding, and at the same time, it can be connected quickly. Therefore, a tpc-et elastomer with high thermal oxidation stability was developed. The weight is reduced by 30%, the cost is low, and the fixed frame is omitted

the first 35% gr-pp intake manifold launched in China

figure 07

the intake manifold of Volkswagen 2015 ea21 1.6L engine (Figure 07) won the award of powertrain category. It adopts g3135x PP of SABIC company and is produced by injection molding process. This is the first intake manifold in China to replace PA 6/6 with 35% gr-pp

this product reduces the cost by%, reduces the weight of molded parts by%, maintains the performance under high temperature conditions, improves the welding strength, and reduces the NVH level by 5 dB. Unique technologies such as fine glass fiber and special sizing technology help to meet performance requirements. The components are welded by vibration

TPO panel cut and welded by robot laser

figure 08

General 2017 Chevrolet Camaro zl1 sports car, which uses robot to cut and weld TPO panel by laser (Figure 08), makes this panel win the award of process/assembly/realization technology category

this product adopts hifax tyc1168x TPO and is manufactured by injection molding process. In the manufacture of class a exterior panels, robot laser cutting and welding processes replace hydraulic punching and ultrasonic welding. Different from other welding processes, the robot laser welding method does not need to thicken the wall material of the welding area to prevent welding penetration when welding the support at the back of the component, which can slightly reduce the weight. The profiling ultrasonic welding head and punching machine are also omitted. The clean cutting operation can be completed within 1 s on the paint side of the component. This dual function process operation procedure is extremely flexible, which reduces the occupied area and tooling cost

seat buffer frame and tank door using polymer composite instead of magnesium

figure 09

seat buffer frame and tank door on Ford 2016 Ford Super Duty Truck (Figure 09) won the safety category award. This product is made of celtran GF lft-pp through injection molding. This is the first time that polymer composites have been used to replace magnesium in structural seat buffer frames and tank doors

the weight of the product remains the same, the cost is reduced (by $4 per set), and all safety and anti-collision requirements are met. Its structure is flexible and can be upgraded to configure future reinforcements. The frame is injection molded with 40% lft-pp, which is also equipped with foamed polypropylene (EPP) anti sinking foam blocks and lockable ergonomic locks. Compared with magnesium alloy materials, the device significantly reduces the carbon footprint
