Aluminum etching and Alodine coating to prevent corrosion and increase bond strength
West System 860 Aluminum Etching Kit
DuPont Acid Etch and Alodine solutions
Submerge Aluminum in etch solution, then submerge in non-diluted Alodine solution
Aluminum stock for insert
Check for appropriate lengths
Bond length increases linearly with bond strength
Gap 0.004 - 0.012 in for hot bonding
Gap 0.008 in for cold bonding
Carved aluminum, tapped for fitting a bearing insert
create shoulder only for grabbing in tensile test
In MIT paper, flashbreaker tape was used to add thickness at the end of the insert to create equal spacing and center insert.
Process for Insert Tensile Test
Cut CF tube into ~3-5 inch sections
ASTM D 695 (compression test)
...
What is being recorded: the compressive strength and compressive modulus of fiber-reinforced plastic composites in the in-plane direction, meaning the direction parallel to the plane of the laminate
Machinery Used: ISO 14126 | ASTM D3410: Shear Loading Compression
Procedure: In-Plane Compressive Properties of Fiber-Reinforced Plastic Composites
Inner Diameter of the Push rod - 0.437"
Inserts: has to be slightly smaller than the inner diameter
