generally rectangular sections that are 25 mm x 100 mm x 1.6 mm.
Purpose: Fixture for preparing test specimens of similar sizes (25 mm x 100 mm x 1.6 mm)
Criteria:
All three adhesive joints curing at the same time
Can be machined in-house
Testing between:
Steel to steel
Composite to composite
Steel to composite
The idea behind this design is to create a “tray” (Fig. 1) to constrain movement in the outer edges of the specimens. Multiple specimens can be cured at the same time in this tray. The spaces between each individual specimen will be separated with skewers (Fig. 2) as well as the spaces between each adhesive joint on a specimen (Fig. 3). A flat board/weights will be placed on top of all specimens to add pressure.
