    Co-Authors: Viktor Kolář, Miroslav Muller, Anna Rudawska, Martin Tichý, Monika Hromasová
    Abstract:

    Adhesive Bonding technology present a perspective method of various materials Bonding and replacing conventional Bonding e.g. welding. A geometric shape modification of Bonding material and an Adhesive reinforcing by glass fibres to increase tensile strength of Adhesive Bond was subject of this research. The Bonding material was modified into preformed angles 5°, 10°, 15°, 20° and Adhesive Bond with 0° was se t as the etalon. The Adhesive was modified by glass fibre with weight 80, 110 and 160 g.m-2. The research proved tensile strength increase from 4 to 48% by various preformed adherent angles. The research also proved tensile strength increase from 4,8 to 93,7% by Adhesive reinforcing with glass fibres with various weight. Statistical analyse proved significant difference between measured values on significance level 0.05 (p < 0.05) i.e. influence of Adhesive Bond modification on mechanical properties was proved.

  • Composite Adhesive Bonds reinforced with microparticle filler based on egg shell waste
    Journal of Physics: Conference Series, 2018
    Co-Authors: Miroslav Muller, Petr Valasek
    Abstract:

    A research on composite Adhesive Bonds reinforced with waste from hen eggs processing, i.e. egg shell waste (ESW) is based on an assumption of the utilization of agricultural/food production waste. The aim of the research is to gain new pieces of knowledge about the material utilization of ESW, i.e. to evaluate possibilities of the use of various concentrations of ESW microparticles smaller than 100 µm based on hen egg shells as the filler in a structural resin used for a creation of Adhesive Bonds from bearing metal elements. An Adhesive Bond strength, an elongation at break and a fracture surface were evaluated within the research on Adhesive Bonds. The experiment results proved the efficiency of ESW filler in the area of composite Adhesive Bonds. The Adhesive Bond strength was increased up of more than 17 % by adding 40 wt.% of ESW microparticles.

  • evaluation of factors influencing Adhesive Bond strength
    Research in Agricultural Engineering, 2018
    Co-Authors: Miroslav Muller, Petr Hrabe, Rostislav Choteborsky, D Herak
    Abstract:

    in the last ten years periods the Bonding technology noted a great boom not only in manufacturing industry but in repairing industry, too. The expansion of chemical industry is the cause of this boom. in this way the use of Bonding technology in industrial applications brings considerable cost savings. For the successful use of Adhesives the knowledge of used Adhesives and of further affecting factors is important. Respecting of this know-how is the presump – tion of the Bonded joint successful design. The breaking of the technological procedure and the incorrect design are very often reasons of wrong joints. The paper contains theoretical in formation about the Bonded joints creation and some results of laboratory tests inquiring into the reasons which affect the Bonded joint strength. For tests the two- component epoxy Adhesives were used.

  • Effect of hydrolysis and denaturation of wheat gluten on Adhesive Bond strength of wood joints
    Journal of Applied Polymer Science, 2013
    Co-Authors: Stefano D'amico, Ulrich Müller, Emmerich Berghofer
    Abstract:

    In this study the Adhesive Bond strength of different wheat glutgluten modifications and the relationship between molecular weight and Adhesive strength was examined. Guanidine hydrochloride and sodium hydroxide were used as denaturation and dispersing agent. Additionally wheat proteins were hydrolyzed by alkaline conditions and enzymes. Effects of different treatments were observed by viscosity measurements and gel electrophoresis. Wood lap joints were prepared with modified proteins and tensile shear strength was tested under dry and wet conditions. In situ hardening of different formulations was analyzed by means of DMA with two-layered specimens in a three-point bending test set-up. Higher solubility had no positive effect on dry Bonding strength and wet Bonding strength was even reduced. Depending on the degree of hydrolysis, significant improvement of Adhesive Bond strength was observed. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

  • Adhesive Bond strength of end grain joints in softwood with varying density
    Holzforschung, 2008
    Co-Authors: Jürgen Follrich, Alfred Teischinger, Wolfgang Gindl, Ulrich Müller
    Abstract:

    Abstract Norway spruce wood specimens covering a wide density range, including density samples between 300 kg m-3 (low density wood) and 750 kg m-3 (high-density compression wood), were joined at end grain surfaces and tested in tension perpendicular to the Bonded surface to estimate the effect of mechanical interlocking on the Adhesive Bond strength. It was hypothesised that the higher the density of the specimens the lower will be the mechanical interlocking of the Adhesive joints due to a reduced penetration of the Adhesive into the cell cavities. An increase of tensile strength was observed with increasing density. These results demonstrate that in the specific case investigated here the cross-sectional cell wall area available for Adhesive Bonding, which correlates with density, is probably more important than mechanical interlocking.

  • Tensile strength of softwood butt end joints. Part 1: Effect of grain angle on Adhesive Bond strength
    Wood Material Science and Engineering, 2007
    Co-Authors: Jürgen Follrich, Alfred Teischinger, Wolfgang Gindl, Ulrich Müller
    Abstract:

    Abstract To study the effect of grain angle on the Adhesive Bond strength in wood, three-part Norway spruce wood specimens were Bonded and tested in tension. The two axially orientated outer parts of the specimens were joined with the middle part by means of three Adhesives typically used for load-bearing constructions, i.e. one-component polyurethane (PUR), melamineureaformaldehyde (MUF) and phenol–resorcinol–formaldehyde (PRF). The grain angle of the middle part was varied from 0° (end grain to end grain) to 90° (flat grain to end grain) in incremental steps of 10°. In general, PRF- and MUF-Bonded samples exhibited highest tensile strength at end grain to end grain orientation of the three parts, while specimens Bonded with PUR showed only 25% of the strength measured for PRF and MUF, respectively. At high grain angles (90°) all specimens showed similar strength values in the range of 30% of maximum strength of MUF- and PRF-Bonded specimens. To explain the changing strength levels at different grain a…

  • Estimation of Adhesive Bond strength in laminated safety glass using guided mechanical waves
    Journal of the Acoustical Society of America, 2012
    Co-Authors: Henrique Reis
    Abstract:

    Laminated safety glass samples with different levels of Adhesive Bond strength were manufactured and tested using mechanical guided waves. The Adhesive Bond strength of the test samples was then also evaluated using the commonly used destructive testing method, i.e., the pummel test method. The interfaces between the plastic interlayer and the two adjacent glass plates are assumed to be imperfect and are modeled using a bed of longitudinal and shear springs. The spring constants were estimated using fracture mechanics concepts in conjunction with surface analysis of the plastic interlayer and of the two adjacent glass plates using atomic force microscopy and profilometer measurements. In addition to mode shape analysis, the phase and energy velocities were calculated and discussed. The guided wave theoretical predictions of adhesion levels using energy velocities were validated using the experimental pummel test results. From the attenuation dispersion curves, it was also observed that the S1 mode exhibits attenuation peaks in specific frequency ranges, and that the attenuation of these peaks is sensitive to the interface adhesion levels. Results show that this guided wave approach is useful in the nondestructive assessment of Adhesive Bond strength in laminated safety glass.

  • Estimation of Adhesive Bond strength in laminated safety glass using guided mechanical waves: Part II. An attenuation approach
    Insight, 2008
    Co-Authors: Henrique Reis
    Abstract:

    Estimation of Adhesive Bond strength in laminated safety glass samples, ie windshields, has been carried out using a multilayered guided wave model and validated using attenuation measurements. As in Part I of this study, the interfaces are treated as imperfect interfaces and modelled as beds of longitudinal and shear springs. The spring constants are estimated using fracture mechanics in conjunction with surface analysis of the plastic interlayer and glass plates via atomic force microscopy and profilometer measurements. Using the multilayered guided wave model, it was observed that the S 1 mode exhibits periodic attenuation peaks in specific frequency ranges, and that the attenuation of these peaks is sensitive to the interface adhesion levels. The mode shapes and power flow profiles corresponding to these peaks are presented and discussed. Experimental attenuation measurements taken on the same laminated safety glass test samples discussed in Part I are presented and discussed to validate the theoretical predicted attenuation values using this multilayered model.

  • Estimation of Adhesive Bond strength in laminated safety glass using guided mechanical waves: Part I. An energy velocity approach
    Insight, 2008
    Co-Authors: Henrique Reis
    Abstract:

    Adhesion levels in laminated safety glass samples, ie windshields, have been assessed using both a non-destructive evaluation method based upon an energy velocity guided wave approach and a commonly used destructive testing method. Laminated safety glass consists of a plastic interlayer surrounded by two glass plates. The interfaces between the plastic interlayer and the two adjacent glass plates are assumed to be imperfect and are modelled using a bed of longitudinal and shear springs. The spring constants are estimated using fracture mechanics in conjunction with surface analysis of the plastic interlayer and of the two adjacent glass plates via atomic force microscopy and profilometer measurements. Energy velocities calculated using this theoretical multilayered model are compared with energy velocity values obtained experimentally using laminated safety glass samples with different adhesion levels. Results show that an energy velocity approach can successfully be used to non-destructively estimate Adhesive Bond strength in laminated safety glass.
