According to the statistics released as the results of researches by the SFB founded by the DFG group, application of plastic with fortified texture in different industries has been under research and survey by several affiliated institutions of Aachen University in Germany.



Application of Plastic with Fortified Texture, One of the Most Advanced Stages of Producing Transportation Vehicles


One of the main issues in this industry that has attracted the attention of researches has been the application of this kind of plastic in automobile manufacturing industry.

The focus of these researches has been on the designs by fortified textures to the development of transportation vehicles by numerical and experimental methods. The potential agents for applying such material in the automobile manufacturing industry will be designed and produced in the near future.



The Vast and Open Area of Design


The ingredients of the material with fortified textures have a vast and open domain in terms of design and structure. The main features of such material like adjustability in size, kind of texture, matrix material, layered structure and so on, play the most significant role in reduction of weight of the constructs in comparison to that of the metal products.


In the SFB 332 researches, the different applications of the fortified plastic in the body and different parts of car “Ford” were examined. The findings of the FRP on these parts developed based on the finding of the metallic current designs, and prototypes were produced. It sounds inevitable to use numerical analysis methods to fully utilize the potentials of material for modern designing and its application in automobile manufacturing industries. The application of numerical analysis in the SFB 332 ranging from sub-structure analysis to designing the whole system was revealed.



Designing Specimen Making in SFB 332


In order to demonstrate the possibilities in the FRB, the required parts for the researches were designed and specimen made. The findings of the previous studies were utilized in designing the parts for the later ones. This stage included all the interconnected stages like, pictorial designing, simulation, specimen making and the lab sample making in the period of the SFB.

Also, demonstrating the reduction of weight of parts in comparison to that of the produced parts based on the current standards was not possible. Some kinds of these parts are elaborated on in the following:


Between 1987 to 1988, some parts of the sledge machine, knitting machine and some front suspension parts were produced. Analyzing the situations in which these parts can be applied including the high dynamic requirements, high safety requirement in case of strike and also special privileges of the RFB that brought about the demands of higher levels (SFB 59).


In the next period, between 1989 to 1992, the front suspensions were optimized and the basic definition of “rim” in the CTS designs were introduced and fundamentally inspected which revealed the requirements for measuring parts. Using numerical calculations specified the under pressure areas and helped calculate the ways to ease the pressure (SFB 92).


Between the years 1993 and 1995, the knower of principles of Korean structures were used to make parts specimen and diverse designs were made in the FRP including, that of a trading car, shank bar and parts of a measuring machine. The structure of the designs in this period was focused on the numerical calculations to measure the hardness, the potential and the reaction of parts to the thermal expansion (SFB 95).


Between the years 1996 and 1998, the researches were concentrated on the different parts of cars. Regarding these parts, measuring based on the dynamic loads played an important role. During the period of optimization of cars, increasing the level of return of reaction to the absorption of energy in designing the FRP structure was crucial. In order to solve this issue, methods of numerical calculation were used to reach the dynamic and static features of parts.



In the researches between 1999 and 2000, the numerous problems of the former periods were surveyed in details.



The structure of the front suspension


One of the main objectives of researches in the field of automobile industry is to optimize the front suspension of cars.

The created structure has the potential to evolve and its result would be to develop the compound structure to absorb the pressure on the chassis. This structure is useful in absorbing energy in case of accident and has passed the dynamic and crash tests successfully. The performance assessment of the whole structure has been done in the Ira Proving Ground System.





The Balancing Rim of Tires


The feasibility studies to determine the impact of two different plans on each other, the concepts of production on the performance features and surveying the structural concepts resulted in the improvements in the wheel rim or the Conti Tire Systems. Also, the fully spiral structure, the compound spiral structure and the press in rim were tested.
