The present invention provides a fastener which does not generate noise when it is engaged to an article and vibration is applied thereto. The fastener comprises a base portion, a stem portion implanted and interconnected to the base portion in a spaced-apart relationship by a predetermined distance from the base portion, and a head portion interconnected to the distal end of the base portion. At least a part of the stem portion or the head portion comprises (1) a polyphase polymer material having a first polymer resin and a second polymer resin, or (2) a polymer resin that increases the flexural modulus of the fastener. Since the fastener does not generate noise during vibration, it is useful as a fastener particularly for fitting automobile components together.

La présente invention se rapporte à un élément de fixation qui ne génère pas de bruit lorsqu'il vient en contact avec un composant et qu'on y applique une vibration. L'élément de fixation comprend une section base, une section tige implantée et interconnectée à la section base, à une distance prédéterminée de la section base, ainsi qu'une section tête interconnectée à l'extrémité distale de la section base. Au moins une partie de la section tige ou de la section tête comprend (1) un matériau polymère polyphasé possédant une première résine polymère et une seconde résine polymère, ou (2) une résine polymère augmentant le module en flexion de l'élément de fixation. Du fait qu'il ne génère pas de bruit lors d'une vibration, ledit élément de fixation convient particulièrement pour assembler des composants d'automobile.
