Technical development program with friendly materials.

Cotetiu, Radu ; Eberst, Otto ; Alexandrescu, Marius 等

1. INTRODUCTION

Romania's economy has gone through a complete process of reorganization since the 1995s and the 1996s. The traditional industrial activities such as mining, the processing of minerals, mining machinery industry etc. have gradually lost ground so today they only make up less than 10% of total industrial output compared with the 1990s. As a result of the reorganization program since 1998 Romania's territory was divided into 8 regions, each one with their own goals and development strategies. Baia Mare which today is a part of the NW Region was a mining center connected with other industries: mining machine industries, mineral processing industries, nonferrous metallurgy etc. Now the areas of the development are: informatics and its subdivisions, aggregate machineries industry, agriculture, tourism, furniture manufacturing, research.

The action-plan put together here is matching with the above presented premium development areas.

The development regions in Romania are: 1. North-East; 2. South-East; 3. South Muntenia; 4. South-West Oltenia; 5. West; 6. North-West; 7. Middle; 8. Bucharest-Ilfov.

2. MATERIAL AND METODOLOGY

The major goal of "The technical development with composites" plan is to develop a research-projects and know-how implementing unit for the North-West region.

In Baia Mare, at the North University we are on the verge of opening a research-projects headquarter where we'll try to attract newly graduated students from the proposed organizations (University and partner companies) developing the skills of people from both university and economic fields and spreading the use of up-to-date, environment friendly plastics in the ranks of machinery engineering and aggregates industry.

As we take in consideration the proper university environment from the North University suitable for PhD dissertations about high performance plastics, we have to notice that the program presents solutions for developing research but also, provides a platform for training of the researchers and attracting highly skilled personal.

3. RESULTS

3.1. Strategical Purposes

1. Implementing the "Technical development program with composites" in the interest of technological development based on new, environment-friendly materials and technologies, being integrated into a managerial research system, in harmony with the regional strategy called "The technology become resource" (material possibilities).

2. Introducing research and development activities based on competitive technologies for the most important areas of industries making possible the spread of using new composite plastics. That goal is reached by growing the material base of the University's research unit in the joint interests of university and industrial fields, efforts which have a great impact on regional and national development.

3. Developing new or updated products using environment friendly materials. We have set up a research-resulted and finished materials monitoring unit and we will study those materials maintainability and operational safety.

4. Effectively using the commercial profitability concept in the industries and inside those communities which need home made new products.

3.2. Presentation of Activities

The activities suggested in this plan are of two types: industrial research and experimental development activities.

1. Studying today used up-to-date materials and those applications on national and international level describing both the materials and their applications. A would be study will reveal the today used plastic materials and their applications in Romania and the perspectives of introducing high capability composite plastics (Cotetiu & Eberst 2003).

Showing the today used environment friendly types of plastics. Studying and analyzing the national specific needs for this domain.

2. Studying the surrounding economic entities' machine equipments and finding ways to modernize those (Cotetiu & Eberst 2003, Eberst &Cotetiu 2003). We will establish a database for companies from the North-West Region's about level of machine equipments showing their maintainability and operational safety (Cotetiu et al., 2000). We will find new possibilities for using high capability plastics modernizing the existing products, machines and aggregates (Cotetiu et al., 2003).

Finding out the effects of machineries and their maintenance and operational safety problems caused to the environment.

-Analyzing the possibilities of making up new products or by modernizing the existent ones due to the usage of new, environment friendly materials.

-Studying the production methodology of items which incorporate high performance plastics. (Kalacska et al. 2000). We present the world-wide novelty regarding researching-developing and modernization methodologies. We'll work out a research method on virtual models to be used on products and machineries which incorporate high capability plastics (Analyzing up-to-date European methodology tendencies about development and modernization. Learning about research methods based on virtual models).

3. Conducting researches about structures of products incorporating some high capability, environment friendly plastics. We'll present different and specific researching methods compared to metal works such as the following machinery (aggregate) elements made out of plastics: gears, slide bearings, rollers. We'll make the fez ability studies and the necessary technical documentation for materializing products fitted for new or modernized items to be found in this program.

4. Analyzing the specific designing methods for high performance, environment friendly plastics (Eberst, 2005). Detailed descriptions about products development. Identifying and learning about necessary new technologies for products incorporating high performance and environment friendly plastics.

5. Materializing prototypes and making up new prototypes for products and aggregates incorporating high performance plastics.

6. Research under factory, operational conditions, conducting operational test in labs, checking the already accepted technological solutions. Conducting studies about the obtained products' long term testing and compared operational safety. Conducting laboratory tests under overloaded, strained conditions for items including high performance plastics. (Operational test while working. Long term test and operational safety study. Speeded up operational tests (under strain).

7. Giving the research tests' results to the interested economic units, editing and spreading those results.

3.3. Partners

The project partners are: S.C. Adiss S.A., S.C. Proned-Control S.R.L., S.C. TechnoCAD S.A., Development of Small and Medium Enterprises Center from Maramures Foundation (CDIMM), "NORDTECH"--Research Center, Innovation and Technological Transfer Association (CCITT). Coordinator of the project is North University of Baia Mare (www.ubm.ro) and program coordinator: Prof. dr. ing. Radu Cotetiu.

All partners have experience and credibility in their domain of activity. Some of them are leaders in Romania in the matter of manufacturing of equipment. Also, the coordinator has the competence to lead this activity based on an experience and research activity in the domain of friendly materials in industrial and mechanical installations and equipments. A small part of this experience was published. Some papers are listed in title References.

4. CONCLUSIONS, SUGGESTIONS

The expected results, period of activity and quantity analyses are displayed in the Table 1.

The training of the personal so much needed for materialization of this project will be guided through the necessary and interested area of activity promoting results which can be used to make competitive products and technologies. New jobs will appear at the producers and at the users of those products.
