The global automotive industry is driven by environmentaland safety standards, increased longevity due to extendedwarranty and lower costs of production. Consumers are

demanding less frequent maintenance, more comfortable driving experiences, and better fuel economy, with no deterioration in performance.

The reduction of the vehicle weight, driven by the desire forlower CO2 emissions and improved mileage, results in the miniaturization of components and functional integration whichare at the forefront of the auto motive industries' efforts. Legislative requirements, with tight tolerances applied and risingoverall costs are pushing OEMs to identify materials that provide higher performance with lower weight and lower costs.

The demand for smaller, more reliable components made fromlighter high temperature materials which have excellent strengthand flow characteristics has increased. This demand can be metby producing thinner-walled parts made from high performancethermoplastics. In addition, there can be the added benefit ofreducing overall costs by consolidating complex metal partsinto a single injection-molded thermoplastic component.

Industry standards dictate that materials today need to performat 150°C (302°F) or higher depending on the application, whereasyears ago temperature range requirements were 100-120°C(212-248°F). OEMs, for example, are searching for materials thatcan perform up to 180°C (356°F) in the lower areas of steeringcolumns and 220°C (428°F) in turbocharger components. Withthese requirements in mind, and while still meeting the otherdrivers in this industry, it may not be feasible to use metal ortraditional plastics in such hostile environments, where evenlight alloys show a loss in mechanical strength at temperatureranges around 200°C (392°F).

Victrex Polymer Solutions, a division of Victrex plc, manufacturespolyaryletherketones (PAEK) including VICTREX® PEEK polymer.Exhibiting consistent mechanical properties at 150°C (302°F) andhigher, these high performance thermoplastics meet the revisedautomotive industry requirements.

STRUCTURAL STRENGTHWhen considering substitution of metal components with plastic,VICTREX PEEK 90HMF40 provides by far the lowest weight per volume ratio. It allows extremely high weight savings versus metals.

The material is capable of outperforming standard aluminumalloys in weight and profile height, and is almost volume neutralwhen compared to tribo-alloy brass materials. Weight savingsup to 80% are achievable when substituting VICTREX PEEK90HMF40 for metal components.

TOLERANCESTolerances of injection molded parts are usually in the range of0.05% of the dimension required. More and more high precisioninjection molders are now able to hold tolerances down to0.02% and tighter.

SPECIFIC STRENGTHVICTREX PEEK polymer has high tensile strength and low densitycompared to metals. Reinforcing the polymer with choppedglass or carbon fibers yields strength-to-weight ratios that meetor exceed those of common lightweight materials.

Continuous fiber reinforced composites made with a VICTREXPEEK polymer matrix have even higher strength and stiffnessthan some metals..

LONG TERM BEHAVIORThe properties of high performance thermoplastics such as VICTREX PEEK polymer favor its use in automotive applicationsand provide distinct advantages that lead to long-term benefits.With components becoming smaller and weight reductions becoming even more necessary, the use of these materials is becoming more significant and beneficial.

State-of-the-art materials like polyphenylene sulfide (PPS) arebecoming close to their strength limits, but still are recognizedfor dimensional stability. High temperature nylons demonstratehigh stress capabilities, but sometimes have issues with dimensional stability. Amorphous materials like polyetherimide(PEI) have a high stress capability and dimensional stability, but are susceptible to chemical attack.

STRUCTURAL STIFFNESSWhen structural stiffness is more important than strength, VICTREX PEEK 90HMF40 provides by far the lowest weight tospace ratio. Significant weight savings when compared to metals, are achievable. The properties of VICTREX HMF range of materials are similar to those of aluminum but the lower density results in considerably lower weight.

Dimensional stability and long-term stress performance showedimprovements when compared to other materials in temperatureranges above 120°C (248°F).

CREEP RESISTANCECreep may be defined as the deformation observed in a sample versus time under a constant applied stress. VICTREXPEEK polymer has outstanding creep resistance for an engineering thermoplastic material and may sustain large stresses over a useful service life without significant time induced deformation.

The figure below displays the creep behavior of VICTREX PEEK450G and 450CA30 with respect to applied stress, time and temperature. The magnitude of stress, time and temperature required to induce accurately measurable (> 0.5%) strains is exceptionally large for an unfilled polymer. Values of creep modulus may be calculated from such data and used as a measure of resistance to creep deformation. The creep strainfor some of the high performance compounds from the VICTREXPEEK grade range are plotted against time in chart below.

At room temperature both filled and unfilled VICTREX PEEK polymer show excellent creep resistance. At temperatures beyondthe glass tran sition temperature (Tg) only reinforced VICTREX PEEKpolymer will be suitable for structural applications. The apparentmodulus of VICTREX PEEK polymer is in many cases higher thantensile/flexural modulus of other high temperature thermoplastics.

5VICTREX® PEEK Polymer — For Automotive Components

TRIBOLOGYTribology is defined as the interaction of contacting surfacesunder an applied load in relative motion. If the surface of a material is viewed on a microscopic scale, a seemingly smooth finish is, in fact, a series of peaks and troughs. When two materialsare then placed in contact and moved relative to one another,the peaks of both surfaces collide. The removal of material fromthe top of the peaks may be considered as wear, and resistanceto the motion as a frictional force.

VICTREX PEEK polymer, and compounds based on VICTREX PEEKpolymer, are used to form tribological components due to theiroutstanding resistance to wear under high pressure (p) and highvelocity (v) conditions.

The friction and wear behavior of a material may be evaluatedusing one of several test geometries. The data given in this flyerwere generated under dry conditions using the standard ASTMD3702 method on injection molded thrust washers.

BENEFITS FOR WEAR APPLICATIONSs Thermoplastic processing, no secondary operations necessarys Intricate, smaller components can be produceds Compatible with automotive fluidss No swelling in moist environmentss No post annealings RoHS and GADSL compliants High compressive strengths Grades without PTFE availables Increased lifetime and performances Enables the bearing to survive longer under poor

lubrication conditions

VICTREX WG™ polymers offer a lower coefficient of friction compared to other established wear grades from Victrex andalso against thermoset materials such as polyamide-imide (PAI)and polyimide (PI).

Within tribological systems the coefficient of friction varies depending on the choice of counterface material and its surfaceroughness, as well as on the specific conditions of speed andpressure as shown in Figure 10. The specific wear rate shown inFigure 11 is another important consideration in design.

Under these specific conditions, VICTREX WG polymers areshown to be among the highest performing wear grade materials.Bearings for many applications are produced in large numbers,and production speed and costs are critical. Victrex polymers areone of the few high performance tribological materials whichcan be injection molded to form finished components withoutfurther thermal treatment. Although PV values are a usefulguide to comparative tribological performance, there are noabsolute values because identical experimental conditions cannot be reproduced.
