This specification covers the engineering requirements for preparing surfaces of polytetrafluoroethylene (PTFE) for bonding and the properties resulting from the treatment. This process has been used typically for rendering surfaces of parts capable of supporting a high strength adhesive bond. The bonding preparation can affect the electrical properties of the PTFE and this should be considered before using it for treatment of electronic components.

Abstract Vapor management system is critical to manage fuel tank capacity, evaporative emissions and pressure control for hybrid applications. Due to stringent emission norms and other regulations there has been lot of advancements in design and application of vapor control valves that are used in automotive fuel tanks. Continuous exposure of these valves to fuel vapor or fuel in some instances led to swelling of assemblies and poses serious threat to product functionality and maintaining required tolerances. Swelling of plastics in fuel is ideally a case of multi physics, which involves modeling of complex mass transfer phenomena. In this study a simple thermal analogous approach has been used to model swelling behavior by characterizing the basic plastic-fuel soaking through coefficient of hygroscopic swelling. Extensive testing has been performed with multiple plastic-fuel combinations with different shapes at different temperatures.

Abstract As a result of the increasing use of fibre reinforced plastic (FRP) components in a modern commercial aircraft, manufacturers are facing new challenges - especially with regards to the realisation of significant build rates. One challenge is the larger variation of the thickness of FRP components compared with metal parts that can normally be manufactured within a very narrow thickness tolerance bandwidth. The larger thickness variation of composite structures has an impact on the shape of the component and especially on the surfaces intended to be joined together with other components. As a result, gaps between the components to be assembled could be encountered. However, from a structural point of view, gaps can only be accepted to a certain extent in order to maintain the structural integrity of the joint. Today's state of the art technologies to close gaps between FRP structures comprise shimming methods using liquid and solid shims.

This specification establishes the requirements for an expanded polytetrafluoroethylene (EPTFE) in the form of sealing tape requiring no curing.

This tape has been used typically for sealing aircraft access panels, pressure barriers, mold line surface close-out panels where gaskets are required, but usage is not limited to such applications. The tape is resistant to aircraft fuels, fluids an lubricants, and is capable of withstanding long-term exposure from -65 to +450 degrees F (-54 to +232 degress C) with short term exposures up to 6000 degrees F (315 degrees C).

Abstract A new damage model based on the Continuum Damage Model [Ref. 1] has been implemented in MSC Marc. It can simulate three process of damage evolution namely: void generation, growth and coalescence. By deactivating the element when a certain damage value is reached, users can now simulate a whole range of damage process; from micro crack to macro crack growth. Micromechanical models like continuum damage mechanics (CDM) deal damage and failures as characteristics based on material and not as geometry configuration. These models are analyzed and validated only for simple geometrical configurations like uniaxial tensile bar, rotating beam specimen etc. A detailed assessment of the geometry transferability, mesh sensitivity and plasticity effects has been addressed only in a limited number of works.

Abstract This breakthrough development involves material conversion from aluminum die cast to polypropylene long fiber thermoplastic (40% long glass filled) for a two wheeler bracket of a leading automotive OEM. The plastic bracket was developed working in collaboration with the molder, glass supplier, technology collaborator and the OEM. The new part needed to be designed lighter in weight, easier to process and suitable for painting, outdoor exposure and stringent dynamic conditions. The scope of this study includes the evaluation of the new material from different viewpoints and comparison of the same with the existing material. The submission will go through the intricate analyses carried out in the development process and highlight the key advantages over aluminum. Studies will include static and dynamic analysis, fiber orientation studies, gate location studies, etc.

Abstract Natural fiber-based composites such as jute-polyester composites have the potential to be more cost-effective and environment-friendly substitutes for glass fiber-reinforced composites which are commonly found in many applications. In an earlier study (Mache and Deb [1]), jute-polyester composite tubes of circular and square cross-sections were shown to perform competitively under axial impact loading conditions when compared to similar components made of bidirectional E-glass fiber mats and thermo-setting polyester resin. For jute-reinforced plastic panels to be feasible solutions for automotive interior trim panels, laminates made of such materials should have adequate perforation resistance. In the current study, a systematic characterization of jute-polyester and glass-polyester composite laminates made by compression molding is at first carried out under quasi-static tensile, compressive and flexural loading conditions.

Abstract Light weighting is a critical objective in the automotive industry to improve fuel efficiency. But when redesigning parts for light weight, by changing from metal to plastic, the resulting design gives NVH issues due to differences in part mass and material stiffness. Many parts were not converted from metal to plastic because of NVH issues that could not be solved. Many engine parts such as cylinder head cover, air intake manifold, oil pan and etc. previously made of metal have since long been replaced with plastic. But timing chain cover has not been replaced because of the aforementioned issue. Sealing performance due to the dynamic characteristics of the application is another challenging factor. In this paper, the key aspects of the plastic timing chain cover as well as its advantage are presented.
