fatigue strength of retaining claws<\/h3>\n<p>For the operation of the Wuppertal suspension railroad, so-called retaining claws made of 30% glass fiber reinforced polyamide 6 (PA6 GF30) are used, which structurally fasten the conductor rail along the entire route. The retaining claws are arranged in pairs to grip the conductor rail. During installation and operation of the track, the retaining claws are subjected to both static loads due to the rail&#8217;s own weight and oscillating loads when passenger trains pass over them. To ensure the operational safety of different samples of a new batch, the retaining claws are characterised with regard to their mechanical properties under static and dynamic cyclic loads. Batch inspections are indicated due to regular replacement intervals.<\/p>\n<h3>Analysis method: Quasi-static testing and fatigue tests based on field tests<\/h3>\n<p>Laboratory tests are used to experimentally determine the force\/elongation behavior and the subsequent correlation with static loads in the installed state (field test) as well as the static loads in connection with assembly processes, such as hanging, bending in a curved position or hammer blows.<\/p>\n<hr \/>\n<p>Further field tests are used to determine dynamic loads that occur when passenger trains pass. The mean and peak loads determined from both field tests are used as input parameters for dynamic-cyclic fatigue tests in the installed state and serve to check the operational stability.<\/p>\n<h3>Result: Confirmation of operational stability under laboratory conditions<\/h3>\n<figure id=\"attachment_2760\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2760\" src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/KAP-Praxisbeispiel-Bauteilpruefung-Betriebsfestigkeit-von-Halteklauen_2.jpg\" alt=\"\" width=\"300\" height=\"168\" \/><figcaption class=\"wp-caption-text\">Result of the field tests, from which the strains on the retaining claw are derived based on assembly processes (1-3 hanging of the rail, 4 bending of a curve and 5 hammer blows). <i>IKV<\/i><\/figcaption><\/figure>\n<p>Based on the strain loads determined in field tests using assembly and overrun processes, average loads and peak loads for the dynamic fatigue test can be assigned in correlation with the laboratory tests. Based on this, retaining claws are dynamically and cyclically loaded at an average of 2,500 N +\/- 700 N for up to 5 million load cycles. All pairs of retaining claws tested achieve the target number of load cycles of 5 million load cycles without any abrupt changes in their properties, resulting in an estimated fatigue strength of approx. 12 years. As replacement intervals are scheduled in the maintenance plan after ten years, the retaining claws can be used as intended.<\/p>\n    <article itemscope itemtype=\"http:\/\/schema.org\/Person\" class=\" border-t border-green border-dotted pt-base mt-base\">\n        <figure class=\" dn_no_select  rounded-full  w-[10em] h-auto object-cov overflow-hidden mb-base bigInMiddle\"><img decoding=\"async\"  class=\"dn-no-drag w-full h-auto object-cover\"  src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-scaled.jpg\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-scaled.jpg 2560w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-748x748.jpg 748w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-1536x1536.jpg 1536w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-335x335.jpg 335w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-768x768.jpg 768w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Christiane-Wintgens-Square-2048x2048.jpg 2048w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" width=\"2560\" height=\"2560\" alt=\"Christiane-Wintgens-Square\" loading=\"lazy\" \/><\/figure>        <h2 itemprop='name' class=\"font-bold\">\n            Dipl.-Ing.

class=\"wp-caption-text\">Car with hood made of CFRP (carbon fiber reinforced plastic) <i>IKV<\/i><\/figcaption><\/figure>\n<h3>Problem: Describing the failure behavior of CFRP<\/h3>\n<p>Carbon fiber reinforced plastics (CFRP) are already widely used in the automotive industry due to their potential in lightweight construction. When designed accordingly, the components exhibit excellent rigidity. In the individual layers of these often highly stressed components, unfavorable orientation and concentration of the forces to be transmitted lead to failure of the composite. The failure behavior must be analyzed in test procedures that take into account the special requirements of the application, material and processing.<\/p>\n<h3>Methodology: Check tear propagation behavior<\/h3>\n<p>According to the problem described, the separation behavior of CFRP components within the layers is to be analyzed. Among other things, the tear propagation behavior is determined in accordance with the ASTM 5528 standard. The test specimen is created as a composite using the defined manufacturing process and, if necessary, conditioned in a defined climate. In addition, a defined pre-damage is created within the layer to be tested. To adapt the test specimen to the universal testing machine used, a device is used that applies the typical tear propagation load to the composite. The laminar failure behavior of the composite is determined as a function of the applied load, the duration of the load application and the selected loading speed.<\/p>\n<figure id=\"attachment_2771\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2771\" src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-CFK-Motorhaube-Rissfortschritt-1.jpg\" alt=\"\" width=\"847\" height=\"565\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-CFK-Motorhaube-Rissfortschritt-1.jpg 847w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-CFK-Motorhaube-Rissfortschritt-1-748x499.jpg 748w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-CFK-Motorhaube-Rissfortschritt-1-768x512.jpg 768w\" sizes=\"auto, (max-width: 847px) 100vw, 847px\" \/><figcaption class=\"wp-caption-text\">Universal testing machine with device that applies the typical tear propagation load to the composite <i>IKV<\/i><\/figcaption><\/figure>\n<h3>Result: Comparable characteristic values<\/h3>\n<p>Based on these investigations, the aim is to achieve efficient utilisation of the components across the entire component.

The tanks are manufactured using the extrusion blow molding process or the half-shell process. Due to the process, there is a significant reduction in the barrier layer thickness (EVOH) in the pinch seam area, which means that these areas have a significantly reduced barrier effect, which can jeopardise approval. Microscopic examinations of the EVOH layer in the critical component area will be used to test the effect of varying process parameters in order to identify an optimum operating point in this respect.<\/p>\n<figure id=\"attachment_2728\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2728\" src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-Kraftstofftank.jpg\" alt=\"\" width=\"847\" height=\"380\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-Kraftstofftank.jpg 847w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-Kraftstofftank-748x336.jpg 748w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/09\/IKV-KAP-Praxisbeispiel-Kraftstofftank-768x345.jpg 768w\" sizes=\"auto, (max-width: 847px) 100vw, 847px\" \/><figcaption class=\"wp-caption-text\">Thin section pick-up of plastic fuel tank in the pinch weld area <i>IKV<\/i><\/figcaption><\/figure>\n<h3>Methodology: Microtome sections with selective phase contrasting<\/h3>\n<p>First, a thin section was made perpendicular to the course of the pinchweld at room temperature. Since the individual layers of the tank wall hardly form any contrasts in the thin section, selective phase contrasting of the EVOH layer was carried out in a dye solution.<\/p>\n<hr \/>\n<p>The hygroscopic property of EVOH causes dye absorption (pink-colored in the image). This makes it possible to clearly recognise and quantitatively evaluate the EVOH barrier down to very narrow layer areas<\/p>\n<h3>Result: Weak point in the area of the pinch weld<\/h3>\n<p>In the bright field, it was thus possible to quickly deliver results with the help of software-supported layer thickness determination accompanied by a wide variation of parameters. As a result, the effect of process parameters on the thickness and quality of the EVOH layer can be visualised and the process can be optimised with regard to product quality.<\/p>\n    <article
