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.

Slisovatelnost dýh pro použití ve vrstvených lepených materiálech
Krejčíř, Michal
This bachelor work is based on studies of physical and mechanical properties of plywoods with various composition. The goal of research was to determine the influence of pre-pressed beech veneer on bending properties. There is also review of plywoods manufacturing in the work. The properties of plywood were tested according to EN standards and evalueted by descriptive statistics and Analysis of variance.

Posouzení pevnosti lepené spáry u tvarovaných překližek
Dohnal, Martin
This thesis deals with the assessment of the strength of the bond line in beech molded plywood, taken from the company TON a.s. Holešov. There will also be measured selected physical and mechanical properties of plywood. The first part provides an overview of the most commonly used plywood materials and adhesives. The next chapter deals with technological process of production of molded plywood in TON a.s. Holešov. The second part contains a methodology for measuring moisture, density, strength of the bond line, determination of bending strength, modulus of elasticity in bending and the formaldehyde content of the adhesive with subsequent statistical evaluation of measured properties. Compared are samples of plywood bonded with two types of adhesives.

Návrh, výroba a charakterizace překližované desky s využitím skelného vlákna v povrchových vrstvách
Svatoň, Kryštof
Bachelor thesis is dealing with manufacturing of plywood with fiberglass reinforcement. Therein fiberglass is propose to increase mechanical properties. Firstly short review of plywood production, common plywood properties characterization and plywood board properties is of interest. Furthermore the focus was on current possibilities of plywood board reinforcement considering plywood. Secondly the own plywood composition is designed and full method of production, sample preparation and panel testing is described. Density, swelling, bending properties and shear strength of central ply and bonding strength was specified according to EN standards. In the end the results are statistically evaluated, summarized and discussed.

Návrh tvarového elementu pro sportovní výrobek
Ďurovec, Juraj
Bachelor study is concerned with design of contour element for archery. Contour element is made in two variations, from composite and from wooden block, where ergonomic and estetic is regarded. Used are adhesives for production of plywood materials, but also epoxide ones, PVAC and PUR. According to the standards there are made testing samples from used materials and consequently those are tested for chosen properties.
