However, the use of such conventional threaded metal fasteners can also be problematic when one or more engine components include polymer composites
More specifically, polymer composites often include an array of fibers, and forming a channel, especially a threaded channel, to receive at least one threaded metal fastener can lead to fiber breakage and / or abrasion in the polymer composite, leading to polymerization Structural integrity of composite parts is compromised
Additionally, when conventional metal fasteners are used with polymer composite parts, they may experience non-uniform thermal expansion under certain thermal operating conditions due to differences in linear thermal expansion coefficients between the materials
As is known in the art, non-uniform thermal expansion can lead to spin loss and thus reduce the performance and fuel efficiency of engine components

Abstract
Methods of joining components to form vehicle assemblies, such as engine assemblies, are provided. The methods include arranging a first component having a first channel defined therein in a mold, arranging a second component having a second channel defined therein in the mold, and aligning the first and second channel to define a pin-receiving channel. At least one polymeric composite pin is inserted into the pin-receiving channel thereby joining the first and second components, wherein an adhesive is disposed adjacent to at least a portion of the polymeric composite pin.
Description
technical field [0001] The present invention relates to a method of joining parts to form a vehicle assembly, such as an engine assembly, by using at least one polymer composite pin to join the parts together. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Traditionally, engine components for automotive applications are made of metals such as steel and iron. Metal parts are strong and generally have good ductility, durability, strength and impact resistance. While metals have been implemented as acceptable engine components, they have the obvious disadvantage of being bulky and reducing the vehicle's weight efficiency, performance and power, thereby reducing the vehicle's fuel economy. [0004] Weight reduction to improve vehicle fuel economy has prompted the use of various lightweight metal components, such as aluminum and magnesium alloys, and the use of lightweight...
