The surface treatment of the specimens resulted in increased single-lap shear (SLS) strengths before and after hydrothermal aging in 80°C hot water compared to nonpretreated reference specimens. In order to reveal the correlations of laser parameters, resulting surface morphologies and the SLS strength, differently laser pretreated surfaces were characterized at the micro- and nanoscale using optical and scanning electron microscopies. The surface enlargement was quantified with a digital image analysis of cross-sections prepared from the joint interfaces. An analysis of variances (ANOVA) of the SLS results indicated that the laser parameters power and pulse frequency were most critical for obtaining high SLS strengths. Pretreated joint surfaces with a high micro- and nano-surface enlargement and deep solidification structures provide high SLS strengths of up to 50 MPa and almost negligible aging losses of merely 4%. Undercut structures on the pretreated surfaces were found to be beneficial for the mechanical and aging properties when only limited micro- and nanostructuring was applied.","lang":"eng"}],"doi":"10.1080/00218464.2023.2223475","page":"1-31","quality_controlled":"1","publication":"The Journal of Adhesion","type":"journal_article","publication_status":"published","citation":{"ieee":"J.

Single-lap shear tests were performed on hybrid AW 6082-T6–CFRP specimens pretreated with the same pulsed laser surface parameter sets on the metal surface as previously tested, AW 6082-T6–E320 metal adhesive joints. The fracture surfaces were characterized to determine the type of failure and elucidate differences and commonalities in the link between surface structures and single-lap shear strengths. Digital image analyses of the hybrid specimens’ fractured surfaces were used to quantify remaining CFRP fragments on the metallic joint side. The results indicate that high surface enlargements and the presence of undercut structures lead to single-lap shear strengths exceeding 40 MPa and 35 MPa for unaged and aged hybrid specimens, respectively. Whereas for the metal–polymer joints, the trend from high strength to weakly bonded specimens is largely continuous with the degree of surface structuring, hybrid metal–CFRP joints exhibit a drastic drop in joint performance after aging if the laser-generated surface structures are less pronounced with low surface enlargements and crater depths.

The prepreg pressing process allows the curing reaction of epoxy resin and the joining process to occur simultaneously to avoid an additional bonding process step. The surface of the aluminium sheet was pretreated in advance using a pulsed Nd:YAG laser to enhance the bonding properties. In the first step, the shear edge tests investigated the adhesion properties achieved with different consolidation (temperature, time and pressure) and laser parameters. Then, 3-point bending tests were carried out to investigate the influence of the consolidation parameters on the mechanical properties of the Carbon Fibre Reinforced Plastics-laminate.

In the field of manufacturing technology, a wide variety of approaches are being used to improve both resource and energy efficiency. Efficiency as well as sustainability can be improved by creating a circular economy or through energy-efficient recycling processes. As part of the interdisciplinary research group \"Light—Efficient—Mobile\" investigations on the energy-efficient friction-induced recycling process have been carried out at the department of Forming and Machining Technology at Paderborn University. E.g. using the friction-induced recycling process, different formless solid aluminum materials can be direct recycled into semi-finished products in an energy-efficient manner. The results of investigations with regard to the influence of the geometrical shape and filling rate of the aluminum particles to be recycled as well as the rotational speed of the continuously rotating wheel are explained in this paper. In addition to the recycling of aluminum chips, aluminum particles like powders from the field of additive manufacturing are processed. Based on these results, the future potentials of solid-state recycling processes and their contribution to the circular economy are discussed. The main focus here is on future interdisciplinary research projects to achieve circularity in the manufacturing of user-individual semi-finished products as well as the possibility to selectively adjust the product properties with the continuous recycling process.</jats:p>","lang":"eng"}],"title":"Potentials of a friction-induced recycling process to improve resource and energy efficiency in manufacturing technology","keyword":["General Materials Science"],"user_id":"15952"},{"intvolume":"        11","author":[{"first_name":"Florian","full_name":"Pfeifer, Florian","last_name":"Pfeifer","id":"22717"},{"id":"90391","last_name":"Knorr","full_name":"Knorr, Lukas","first_name":"Lukas"},{"first_name":"Florian","full_name":"Schlosser, Florian","id":"88614","last_name":"Schlosser"},{"orcid":"0009-0001-6433-7839","full_name":"Marten, Thorsten","first_name":"Thorsten","last_name":"Marten","id":"338"},{"full_name":"Tröster, Thomas","first_name":"Thomas","id":"553","last_name":"Tröster"}],"department":[{"_id":"9"},{"_id":"149"},{"_id":"321"}],"publication_status":"published","citation":{"short":"F.

The Laser-Powder-Bed-Fusion (L-PBF) and Laser-Metal-Deposition (LMD) processes are considered, as they differ fundamentally in the way a part is manufactured. (2) Known process parameters for low-porosity parts were used to fabricate tensile strength specimens. Half of the specimens were heat-treated, and all specimens were tested for mechanical properties in a quasi-static tensile test. In addition, the material hardness was determined. (3) It was found that, firstly, heat treatment resulted in a sharp increase in mechanical properties such as hardness, elastic modulus, yield strength and ultimate strength. In addition to the increase in these properties, the elongation at break also decreases significantly after heat treatment. The choice of process, on the other hand, does not give either process a clear advantage in terms of mechanical properties but shows that it is necessary to consider the essential mechanical properties for a desired application.</jats:p>","lang":"eng"}],"file":[{"relation":"main_file","date_updated":"2024-11-22T15:55:07Z","success":1,"creator":"cboedger","file_size":5838834,"file_name":"crystals-13-00157.pdf","access_level":"closed","file_id":"57334","content_type":"application/pdf","date_created":"2024-11-22T15:55:07Z"}],"title":"Comparative Study of the Influence of Heat Treatment and Additive Manufacturing Process (LMD &amp; L-PBF) on the Mechanical Properties of Specimens Manufactured from 1.2709","issue":"2","article_number":"157","volume":13,"type":"journal_article","ddc":["670"],"publication":"Crystals","quality_controlled":"1","department":[{"_id":"149"},{"_id":"9"},{"_id":"321"}],"publication_status":"published","citation":{"short":"S.

The stacking sequence of the unidirectional plies forming a CFRP laminate, and their thicknesses, primarily determine the mechanical performance. However, during manufacturing, defects, e.g., pores and residual stresses, are induced, both affecting the mechanical properties. The objective of the present work is to accurately measure residual stresses in CFRPs as well as to investigate the effects of stacking sequence, overall laminate thickness, and the presence of pores on the residual stress state. Residual stresses were measured through the incremental hole-drilling method (HDM). Adequate procedures have been applied to evaluate the residual stresses for orthotropic materials, including calculating the calibration coefficients through finite element analysis (FEA) based on stacking sequence, laminate thickness and mechanical properties. Using optical microscopy (OM) and computed tomography (CT), profound insights into the cross-sectional and three-dimensional microstructure, e.g., location and shape of process-induced pores, were obtained. This microstructural information allowed for a comprehensive understanding of the experimentally determined strain and stress results, particularly at the transition zone between the individual plies. The effect of pores on residual stresses was investigated by considering pores to calculate the calibration coefficients at a depth of 0.06 mm to 0.12 mm in the model and utilizing these results for residual stress evaluation. A maximum difference of 46% in stress between defect-free and porous material sample conditions was observed at a hole depth of 0.65 mm. The significance of employing correctly calculated coefficients for the residual stress evaluation is highlighted by mechanical validation tests.</jats:p>","lang":"eng"}],"doi":"10.3390/jcs6050138","_id":"31496","date_updated":"2023-04-28T11:31:42Z","date_created":"2022-05-30T07:04:34Z","funded_apc":"1","publisher":"MDPI AG","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2504-477X"]},"year":"2022","status":"public","citation":{"chicago":"Wu, Tao, Roland Kruse, Steffen Rainer Tinkloh, Thomas Tröster, Wolfgang Zinn, Christian Lauhoff, and Thomas Niendorf. “Experimental Analysis of Residual Stresses in CFRPs through Hole-Drilling Method: The Role of Stacking Sequence, Thickness, and Defects.” <i>Journal of Composites Science</i> 6, no. 5 (2022). <a href=\"https://doi.org/10.3390/jcs6050138\">https://doi.org/10.3390/jcs6050138</a>.","ieee":"T.

In general, the conditions in a deep-drawing process change due to changing tribology conditions, varying degrees of spring back, or scattering material properties in the sheet blanks, which affects the resulting pre-strain. Mechanical joining processes, especially clinching, are influenced by these process-related pre-strains. The final geometric shape of a clinched joint is affected to a significant level by the prior material deformation when joining with constant process parameters. That leads to a change in the stiffness and force transmission in the clinched joint due to the different geometric dimensions, such as interlock, neck thickness and bottom thickness, which directly affect the load bearing capacity. Here, the influence of the pre-straining in the deep drawing process on the force distribution in clinch points in an automotive assembly is investigated by finite-element models numerically. In further studies, the results are implemented in an optimization tool for designing clinched components. The methodology starts with a pre-straining of metal sheets. This step is followed by 2D rotationally symmetric forming simulations of the joining process. The resulting mesh of each forming simulation is rotated and 3D models are obtained. The clinched joint solid model with pre-strains is used further to determine the joint stiffnesses. With the simulation of the same test set-up with an equivalent point-connector model, the equivalent stiffness for each pre-strain combination is determined. Simulations are performed on a clinched component to assess the influence of pre-strain and sheet thinning on the clinched joint loadings by using the equivalent stiffnesses. The investigations clearly show that for the selected component, the loadings at the clinch points are dependent on the sheet thinning and the stiffnesses due to pre-strain. The magnitude of the influence varies depending on the quantity considered. For example, the shear force is more sensitive to the joint stiffness than to the sheet thinning.</jats:p>","lang":"eng"}],"doi":"10.1007/s11740-021-01103-w","keyword":["Industrial and Manufacturing Engineering","Mechanical Engineering"],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s11740-021-01103-w"}],"user_id":"38177","oa":"1","publication":"Production Engineering","quality_controlled":"1","type":"journal_article"}]
