Vliv barevného odstínu pigmentové povrchové úpravy na teplotu povrchu nábytkových dílců
Plodíková, Lucie
The bachelor thesis based on experimental measurements of previously prepared samples. The samples are made of beech plywood. They are finished by pickling with various pigments and exposed to daylight in exterior. The thesis investigates influence of colour shade of pigment surface finishing on wood furniture to the physic-mechanical properties of surface finishing but mainly to the temperature of finished surface. Other properties examined are hardness, adhesion, and colour shade, degree of damage and abrasion resistance. The result of thesis is evaluation and description of achievements with the contribution for practice and new findings.

Návrh materiálu na bázi dřeva s požární odolností
Jeřábková, Lucie
Bachelor thesis compares the properties of composite materials with basalt fiber or with glass fiber. The main objective is comparison of the mechanical properties, which include fire resistance. Concretely, thesis will deal with bending properties of composite material with basalt fiber. These properties of composite material with basalt fiber will be compared with the bending properties of the composite material with glass fiber and plywood. The second part will deal with fire resistance of composite material with basalt fiber and will compare with the fire resistance plywood and composite material with glass fiber. Finally will be made a test of the surface resistant against falling bullet.

The analysis of acoustic properties of innovative wood-based materials
Svojanovský, Jan ; Nop, Patrik (referee) ; Jirásek, Ondřej (advisor)
The content of this work is research of innovative wood-based materials in the acous-tic perspective. Basically, the goal is to determine the influence of the internal structure of the wood-based material on variables, which are sound speed, acoustic resistance, or acous-tic constant. In total were measured 15 samples, each one was made in a different way. Each sam-ple was weighted, and the length of its sides was measured. By using the ultra sonic timer, it was measured the time of the sound impulses, which go through the samples in all of their axes for the purpose of observation the influence the fibers on speed of sound in the materi-al. The next thing to do was to determine another magnitude, which describe acoustic of the material. All measurements were taken in room conditions (room humidity). Six of the sam-ples, which were randomly selected from those 15 samples, were measured once again after two weeks. In those two weeks were all the samples saved in air-conditioned place in which was the room humidity distinct lower. In the end all the samples were compared with each other and they were also com-pared with materials which are commonly used in production of musical instruments or acoustic components. Possible use in the music industry was assigned to each sample.

Home office
Veverková, Lenka
The content of this thesis is a design of portable home office. The theoretical part includes a historical overview of worktables development from the middle ages to the present, also trends in home office design. Before designing itself was necessary to define the concept of home office and to define the requirements for this proposed product, which also includes a detailed survey of the target group. In the next section is presentation of final design with sketches and 3D visualizations. The final design is described in material, construction and technology.

Bio-based wood adhesive derived from brewers spent grain
Muselíková, Vladislava
Brewers spent grain (BSG) is an abundant waste material from the brewing process, representing approximately 85% of total by-products generated, is rich in cellulose and non-cellulosic polysaccharides and has a strong potential to be recycled. One of the main components of the BSG is protein, which has a potential to be extracted, modified and used as an adhesive for the woodworking adhesive. This work deals with the protein extraction through alkali treatment and its subsequent modification, crosslinking with glyoxal. The crosslinked adhesive was tested through ABES method to find, that ideal content of glyoxal is 20%. Subsequent adjusted standard tests for the lap shear strength and bend strength (MOE and MOR values) were used to compare its values to commercially available PVAc adhesive. The lap shear strength results were 2,7 times lower to PVAc, the bend strength values were, on the other hand, 1,5 times higher. The PVAc was partially replaced (50 and 25%) by the protein adhesive showing that the extracted adhesive could serve as a partial replacement to lower the ecological impact of the PVAc adhesive.

Redesign sedacího prvku pro děti
Černochová, Lucie
The bachelor thesis is focused on sitting furniture, specifically on a growing chair for a child. The thesis is divided into two main parts. At first, in the theoretical part, there is described a history of sitting furniture, anthropometry, ergonomics and its criteria for right sitting, ways of sitting and safety. This part is finished by a short research of already existing growing chairs for children. In the practical part there is gradually described a whole process of making a growing chair for a child. At first, this part is focused on chair designs itselves, which are drawn in sketches. Furthermore, there is described a production of a model in 1:1 scale which is followed by visualisations of the growing chair modelled in a program Autodesk 3DS Max 2015. The result of this thesis is a manufactured prototype of the designed growing chair for a child.

Návrh sedacího prvku do interiéru
Vačevová, Kristýna
The content of this thesis is consistent and complex rework the existing prototype of the seating rest element created at the object Furniture Design Studio II at the follow-up study. The output is a new realization of the remaked prototype. The thesis is divided into two parts - theoretical and practical. The theoretical part maps the issue of sitting - from historical, ergonomic views and used materials and technologies, too. In this thesis is also included an overview of sources of inspiration for the initial creation. Practical part includes the first sketches, 3D visualizations,the real photos from production, a brief technical documentation and description of the first and the second prototype production, too. Also there are some other variants of this rest chair. At the end of this work dit there is the chapter called Marketing are describes the possibilities of further variable product processing, approach for determinating price of the product at the rest furniture market, its distribution and marketing communication.

Lempera, Martin
The bachelor´s work deals with problematics of longitudinal setting of plywood materials, for a purpose of comparing of mechanical features of particular glue mixtures at the connecting at chamfer. The first part of the work deals with characteristics, production and division of plywood boards. Follows the information about connecting and surface finish of plywood boards. The second part of the work contains methodology of carrying out tests and results of particular groups of samples according to glued materials. The main testing of samples was focused on modulus of rupture (MOR) and modulus of elasticity (MOE). Further performed tests were for a purpose of finding out of: moisture, density, durability of edges, their dampness and resistance of surfaces of plywood boards against abrasion.

Návrh nábytkového prvku pro konkrétního výrobce
Dočkal, Filip
This thesis focuses on plywood flat-pack furniture made with CNC technology. In the first part of the thesis there is an evolution of the flat-pack furniture, its contemporary tendencies and a list of a current market supply. However, the main theme is a design process of furniture object for a new furniture brand called REXTA. Since the objects construction is based on modular system, user is able to utilize his living space in more effective ways. The thesis contain also a product development process after creation of a prototype, construction strength test and introduction of the results through expositions and online media.
