English: Sterigma (made of composite: polyamide 6-6 with 30 % glassfiber), dimensions 90x25 mm, black, and epoxy adhesive, thickness 2 mm, blue, to prepare 3 tensile test specimens.
Français : Préparation de 3 éprouvettes à recouvrement simple (type stérigme/adhésif/stérigme) normalisées (industrie automobile) pour un essai destructif de résistance en traction-cisaillement (RTC) destiné à évaluer la performance d'un assemblage collé, à partir de :
Ces éprouvettes subiront une cuisson (à environ 180 °C pendant 30 min). Après un conditionnement (à 23 °C pendant 24 h), un essai de traction-cisaillement sera réalisé pour mesurer (à 23 °C) la RTC des éprouvettes collées. Ce type d'essai est très souvent utilisé. On utilise une machine de traction universelle ; vitesse de traction : 10 mm/min. Pour cet exemple, on trouve une résistance d'environ 2 MPa (valeur moyenne sur 3 essais minimum). Note : une épaisseur de joint de colle plus faible (par exemple 0,2 mm : cas des collages structuraux) donnera, toutes choses égales par ailleurs, une résistance plus élevée. |
