Summary

[edit]
Description
Français : Courbe de compression à une vitesse de 25 mm/min : force (en kN) en fonction du déplacement de la traverse (en mm). Le module de compression Ec est calculé à partir de la partie linéaire initiale de la courbe (ici entre 2 et 4 mm, environ). Détermination de la résistance à la compression σc. Moyennes sur au moins 5 essais.
L'éprouvette normalisée est un cylindre (diamètre 35 mm ; hauteur 100 mm) en composite époxyde à renfort de verre (fibre de verre ou microbilles de verre, suivant la formulation) cuit à 180 °C pendant 30 min.
English: Compression curve at speed = 25 mm/min: load (kN) against displacement (mm).

Standardized test cylinders made of glass-epoxy composite (35 mm diameter; 100 mm height).

Determination of compression modulus Ec and compression strength σc.
