Start with the engineering decision
Define the existing and proposed core forms, target thickness, component role and technical evidence required by the programme. The comparison should not assume that either material family is universally better. It must be tied to the selected product documents and the actual component requirements.
Translate the component into a controlled core brief
Surface contours, edge details, local interfaces, machined features and nesting requirements should be reviewed from the drawing. A material change can affect how the core starts, how it is prepared and how it is protected before lay-up. These are practical selection questions, not marketing details.
Connect the material question to the process route
State the sandwich construction, bonding or resin route, temperature and pressure context, machining needs and handling sequence. A comparison should account for the full workflow rather than reducing the decision to an isolated density or strength field that may not be comparable across products.
Keep technical evidence within its stated boundary
Use current grade documentation and project acceptance criteria. If the project considers a replacement, identify any required trials, drawing changes or validation activities as project actions. A web article may prepare the conversation but should never present a substitute as already approved.

01Can PMI foam be presented as an automatic replacement for balsa?
No. Any change must be assessed against actual product data, component geometry, process and programme requirements.
02What makes a material-switch RFQ more useful?
Provide the existing construction, proposed component, drawings, candidate materials, process route, data needs and the decisions that require verification.
