Composite specimens for double-cantilever beam (DCB), end-notched flexure (ENF) tensile and flexural tests were prepared and tested according to ASTM standards with perlite contents of 1, 3, 5 and 10 wt%.
For this purpose, specimens for a double cantilever beam test were produced and tested in an Instron tensile machine, which includes an environmental chamber to control the test temperature; each lot of specimens was tested at 20, 50 and 80 °C respectively, at a speed of 1 mm/min.
For those specimens with double bolt line layout, the capacities are underestimated by all the considered standards.
The cyclic hardening was more accelerated for specimens deformed by double prism slips than for those deformed by single prism slip.
A 57-gram (2-ounce) specimen, for example, can double its weight in one feeding.
a Double curvature specimen (Setup Type A), b Cantilever specimen (Setup Type B), c Specimen with single stub (Setup Type C), d Specimen with Double stub (Setup Type D).
Results for double cantilever beam DCB, end-loaded split (ELS) and fixed-ratio mixed mode (FRMM) specimens are presented.
Shear type damage was observed for three specimens tested under double curvature.
Specimens were double stained with basic fuchsin and methylene blue.
Try for double exposures.
