Learning Targets
- Distinguish permanent, removable, and adjustable connection methods.
- Compare adhesives and fasteners using relevant design criteria.
- Predict a possible connection failure and propose a prevention step.
IED Unit 1 • Lesson 1.15
Adhesives & Fasteners
Focus question: How do engineers decide the best way to connect parts together?

The selected method fits the materials, access, loading, and future service needs of the joint.

Opening Prompt
Why might the strongest adhesive still be the wrong choice for a connection?
Think first, then be ready to share a short response that connects the question to engineering communication.
Reveal: why this matters
The joint may need to be inspected, repaired, or disassembled. Material compatibility, access, cure time, mass, and serviceability can matter as much as maximum strength.
Core Skill
What We Are Practicing
Connection methods may be permanent, removable, adjustable, or temporary.
Adhesives and fasteners perform differently depending on materials and joint conditions.
A good selection balances strength with access, assembly, inspection, and repair needs.
Lesson Interactive
Connection Method Trade Study
Select the requirements for an example rocket access-panel joint. The tool recommends a connection method based on the chosen criteria.
Current Recommendation
Structural epoxyBest for a permanent bond.
A real selection must also consider material compatibility, available edge distance, environment, and manufacturing access.
Choose at least two requirements so the recommendation is based on engineering criteria.
Your Task
Select a Connection Method for the Rocket
Evaluate one connection between two rocket components and recommend an appropriate adhesive or fastener.
- Identify the materials, expected direction of force, available access, and whether the joint must be removable.
- Compare at least three joining options in a simple criteria table.
- Sketch the selected joint and show the fastener location or adhesive area.
- Identify one likely failure mode and a step that would reduce the risk.
Quality check: The recommendation must connect each important joint requirement to evidence from the comparison.
What You Will Submit
Adhesive and Fastener Decision
Submit one comparison package and one recommendation.
Submission standard: Do not choose a permanent joint without considering future inspection or disassembly needs.
