Title: Biobased and biodegradable polymer materials and its composites – mechanical properties and application
Title: Biobased and biodegradable polymer materials and its composites – mechanical properties and application
Polymer materials do not have a very good reputation in recent times due to their problems with recycling from municipal waste. Most of this waste is represented by various types of packaging: PET bottles, films, tubes, caps. These materials has an unique properties, it is cheap and fast for large-scale production but over 40 % of total production of polymers will transform into packaging. We can see a lot of floating packaging, foil, disposable gloves in oceans or lakes. European Union regulations prohibit the use of disposable packaging products from 2021 but in times of a pandemic, disposable packaging allows us to maintain cleanliness and the possibility of using catering, restaurants.
We can use biodegradable polymers which has a possibility of degradation in the soil and control condition of composter. There is a one barrier of that solution – price of that kind of materials. There is a one way to make a better material and cheaper one. Physical modification of polymer materials is easy way to cheap and fast modification mechanical properties and reducing raw material in produced parts. There are a lot of fillers can be used in polymers – calcium carbonite, cretaceous (chalk), geofillers (minerals), biochar and wastes from plant production. That’s materials and its composites are one of the area of scientific research conducted in Department of Technology and Automation (Polymer Processing Team). Well equipped technological and research laboratory gives our scientists and visiting students the opportunity for development and cooperation with industry and other universities.

ABSTRACT
Title: Drilling Holes without Chip
Title: Drilling Holes without Chip
Traditionally holes are made in metal by drilling with a multi point cutting tool. Hole making is a crucial process to facilitate assembly of components using fasteners. Friction drilling has evolved as a nontraditional technique for hole making. Friction drilling involves making holes in metal with the aid of frictional heat, through which the material in plastic state is extruded to form the hole. The friction drilling process is also called thermal drilling, form drilling, flow drilling, or friction stir drilling. Generally materials having thickness less than 5mm can be drilled using friction drilling process. The conical tipped friction drill tool is made of a wide variety of materials namely tool steel, high speed steel, tungsten carbide and H13 steel. The tool life could be increased by heat treating and applying wear resistant coatings. The selection proper process parameters and application of optimization techniques such as design of experiments and Taguchi method gives better quality holes. Since the friction drilling produces does not produce any chip and needs no coolant, this technique is a potential green manufacturing technology.
Key words: Friction Drilling (FD), Flow Drilling, form drilling, chip, plastic,optimization.

ABSTRACT
Title: Methods of producing modern, rapidly cooled materials with an amorphous structure
Title: Methods of producing modern, rapidly cooled materials with an amorphous structure
Amorphous materials in the form of alloys are one of the most modern groups of materials. The interest in these materials is due to their unique properties, which are much better compared to their crystalline counterparts with the same chemical composition. Initially, such materials were produced in the form of coatings and thin tapes, the so-called classic amorphous materials (seventies). Obtaining the amorphous structure required high cooling rates in the range of 105-107 K/s. However, it was practically impossible to produce a material thicker than several tens of micrometers at such high cooling rates. The thickness of the produced materials alone was insufficient for their full application. In 1989, three empirical criteria were presented, the application of which makes it possible to systematically produce amorphous materials with a thickness greater than 100 micrometers. This group of materials has been called bulk amorphous materials. Mentioned criteria: the alloy should consist of more than three components whose atomic radii should differ by more than 12% (at least the major components of the alloy) and have a negative heat of mixing. The alloy compositions selected in this way should show good glass transition ability, which means that they can be produced at a much lower cooling rate. Since then, many technical solutions have been developed to enable the production of bulk amorphous alloys. At the Częstochowa University of Technology in Poland, there are several devices with the use of which amorphous materials are produced. The author of the paper is the main designer of one of these devices. During the lecture, four devices for the production of bulk amorphous materials will be discussed, in which the following is used: the suction method, the injection method, a combination of the injection and suction methods, and a method in which the liquid alloy is placed in a copper mold using centrifugal force.

Title: Assessment of Musculoskeletal Disorder in Foodservice Industry in Emerging Economy
Title: Assessment of Musculoskeletal Disorder in Foodservice Industry in Emerging Economy
Musculoskeletal Disorder (MSD) is a major issue affecting many people particularly working for longer shifts in industries in today’s modern societies. It is due to the higher demand of goods and services from various industries and companies operating for long period of hours each day. People working in Papua New Guinean industries are also suffering from MSD like those working in other developing nations. However, the issue of work-related musculoskeletal disorders (WMSDs) in industries/factories and agriculture sector is not that addressed as it should be. Relevant data was collected after critical observation at a food catering unit in Papua New Guinea. The most prevalent MSD at the case organization is observed to be knee pains. From assessment data based on Cornell questionnaires the results indicated that Knees have higher MSD risk for all the 15 samples that were interviewed. Full body analysis data indicates that for both male and female, body parts below the hip has higher MSD score whereas for female the right knee has higher MSD score. According to the P-chart analysis 26.67% of the 15 workers have higher prevalence to MSDs while 73.33% have lower prevalence to MSDs. Results also indicated that right hand has high MSD risks for males in comparison to females. Further, analysis of the results revealed that the 15 workers have demonstrated high MSDs risk for right-hands, 26.67% have high MSDs risk for left hands.

ABSTRACT
Title: Selective Laser Melting (SLM) using multi diode lasers
Title: Selective Laser Melting (SLM) using multi diode lasers
Laser-based additive manufacturing (AM) technologies have developed to a stage where they are massively used to manufacture end-use high-value components from a variety of materials. Compared with traditional fabrication techniques, AM processes are known for their ability to fabricate geometrically complex components that can be easily customised without significant additional cost or lead time delay.
Selective laser melting (SLM) is an AM process that uses a powder bed fusion approach to fully melt layers of powdered metal and create 3D components. Current SLM systems are equipped with either single or multiple (up to four) high power galvo-scanning infrared fibre laser sources operating at a fixed wavelength of 1064 nm. At this wavelength, a limited laser energy absorption takes place for most metals (e.g. alloys of aluminium have less than 10% absorption and titanium 50-60% absorption). The lower absorption of 1064-nm laser sources requires higher laser powers to compensate for the loss of energy due to reflectivity. This makes the use of 1064-nm lasers within current powder bed fusion SLM systems energy inefficient. Further to this, there is limited potential for scale-up of these laser sources within an SLM system due to physical space requirements and high economic cost all of which reduces SLM productivity. o the commercial SLM systems are generally restricted to a laser wavelength of 1064 nm and there is a physical limitation on the number of lasers that could be fitted within a commercial system.
Though industrial uptake of the technology has grown in recent years, SLM has drawn criticism due to limits on productivity. Recent studies have attempted to overcome the limitations of low absorption and efficiency by using a shorter wavelength laser to process powdered metal using Semiconductor diode lasers (wavelengths 405–3300 nm). Diode lasers are among the most efficient lasers sources with up to 60% wall-plug efficiency thus offering the potential to decrease the operational cost and occupies a fraction of the space compared to a fibre laser. These advantages of the diode lasers bring us to our innovation to use multiple diode lasers for area processing to achieve massively high production rates.
