Core Material
- Aluminum Honeycomb
- Nomex Honeycomb
Face sheet materials
- 4 ply either side, should we use Kevlar or Fiberglass for inner layer (galvanic)
- In areas 500mm from driver, do we want to add more layers when adding the Kevlar or remove some layers
Adhesive
- Co-bond using West Systems
- Co-bond using Lam 127
- Secondary bond using West Systems
- Secondary bond using Lam 127
- Secondary bond using Araldite
- Secondary bond using paste epoxy
Filler materials
- This would be for secondary bond epoxies, especially paste epoxies, in order to get ideal bond thickness (4-8 thou)
- This has the potential to strengthen our panels but I have no research to back this up (it just makes sense kinda… right?) and it would have to be completely empirical
Kevlar fiber interfacial toughening (Kevlar Fiber interfacial toughening)

First test plans

Test all with fiber glass as inner layer first, then kevlar

Volume fraction around 55%(will test)

For now, all tests will be 3 ply cf, Kevlar/fiber glass, core, kevlar/fiberglass, 3 ply cf

Nomex core test group:

Control: co-bond w/ West Systems or Lam 127

Config 2: secondary bond w/ West Systems or Lam 127

Config 3: secondary bond w/ araldite

Config 4: secondary bond w/ paste epoxy

Honeycomb properties

Aluminum test group:

Control: co-bond w/ West Systems or Lam 127

Config 2: secondary bond w/ West Systems or Lam 127

Config 3: secondary bond w/ araldite

Config 4: secondary bond w/ paste epoxy
