Description
- This application claims priority under 35 USC 119 to German Patent Appl. No. 10 2012 102 290.9 filed on Mar. 19, 2012, the entire disclosure of which is incorporated herein by reference.
- 1. Field of the Invention
- The invention relates to a mounting part for affixing a fiber composite part of a motor vehicle to at least one adjoining component of the motor vehicle. Furthermore, the invention relates to a fiber composite part, to a method for manufacturing the mounting part and to a method for manufacturing the fiber composite part.
- 2. Description of the Related Art
- Fiber composite parts made from carbon fiber reinforced or glass fiber reinforced polymers are increasingly used in motor vehicles to achieve weight reductions. However, it is necessary to connect the fiber composite parts to at least one adjoining component of the motor vehicle. Mounting parts, or inserts, incorporated in the respective fiber composite part to connect the fiber composite parts to the adjoining component. According to the prior art, these mounting parts incorporated in a fiber composite part are metallic, and usually aluminum.
- The metallic mounting part used for affixing the fiber composite part to an adjoining component of the motor vehicle must be coated with an adhesion promoter and an anti-corrosion agent prior to being introduced into the fiber composite part. As a result, manufacturing expenses are increased.
- Fiber composite parts used with metallic mounting parts are disclosed in WO 2011/051227 A1.
- An object of the present invention is to provide an innovative mounting part for affixing a fiber composite part of a motor vehicle to at least one adjoining component of the motor vehicle, an innovative fiber composite part and a method for manufacturing the mounting part and the fiber composite part.
- The invention relates to mounting parts that are incorporated or embedded in a fiber composite part for affixing the fiber composite part to an adjoining component. The mounting parts of the invention are made from a fiber composite material. As a result, and unlike the prior art, there is no need to coat the mounting parts with an adhesion promoter and an anti-corrosion agent prior to being incorporated, thereby reducing manufacturing expenses. Moreover, the fiber composite mounting parts ensure an integral bond between the mounting parts and the fiber composite part.
- The mounting part is made from a carbon fiber reinforced or a glass fiber reinforced polymer with relatively short fibers between 3 mm and 100 mm in length, and preferably between 20 mm and 80 mm in length. This defined length of the relatively short fibers for the mounting part allows on the one hand the guarantee of a sufficient strength of the mounting part, and on the other hand the provision of a three-dimensional shape analogous to that of metallic mounting parts.
- The mounting part preferably comprises between 30% by volume and 70% by volume, in particular between 40% by volume and 65% by volume, fibers and furthermore between 70% by volume and 30% by volume, in particular between 60% by volume and 35% by volume, a thermosetting polymer. This composition of the mounting part of fibers and thermosetting polymer is advantageous for guaranteeing a high strength of the mounting parts.
- The mounting part preferably is manufactured by preparing a liquid or flowable mixture of polymer and fibers. The mixture then is filled into a three-dimensionally shaped mold for the mounting part. The mold then is closed and the mounting part is cured for a defined period of time at a defined temperature and a defined pressure. The aforementioned method enables the manufacturing of three-dimensionally shaped mounting parts with sufficient strength from a fiber composite material with simple means. In this context the term “flowable” does not mean that the mixture has to be “flowable” already at room temperature. Rather, the mixture may take the form of a sheet at room temperature and an appropriately weighed amount may be filled into the mold. The mixture conforms to the three-dimensionally shaped mounting part once the mold has been closed on the basis of temperature and pressure.
- The mounting part preferably is cured in the mold for a period of between 0.5 min and 10 min at a temperature between 100° C. and 200° C. and at a pressure of more than 100 bar. The abovementioned process parameters are advantageous, with the tool preferably being heated isothermally during the curing of the mounting part.
