Plates & Panels / Purchasing guide
Do not use “carbon fiber panel” as a complete material specification. First establish whether the requirement is for a solid laminate, a decorative facing or a sandwich construction. These describe different constructions. Procurement should capture the intended function and interfaces before asking a supplier to recommend a specific panel system.

Describe the job the panel must do
Explain how the panel is supported, what attaches to it and whether it is mainly cosmetic or part of a load-bearing assembly. Include the operating environment and any relevant design or test requirements. An attractive surface photograph cannot establish the construction beneath it, and an outside dimension cannot establish structural suitability.
Ask for the construction definition
For a proposed sandwich panel, request the facing specification, core identification, overall thickness and treatment of edges and inserts. For a solid laminate, request its agreed material and construction definition. Keep these requirements in the purchase documentation instead of relying on a product name that different suppliers may interpret differently.
Compare interfaces as well as panels
Check the intended fastener locations, cut-outs and exposed edges against the supplier proposal. Request a sample or drawing review for the actual interface. A panel comparison should include any additional edge finishing or attachment work; otherwise a seemingly similar quotation may omit the work needed to make the panel usable.
Information to include in your enquiry
| Review item | Information to provide |

| Interfaces | Attachments, inserts, cut-outs and edge treatment |
| Evidence | Agreed material documentation and relevant validation |
Frequently asked questions
Can thickness alone identify a sandwich panel?
No. Ask for a construction description or an approved section drawing rather than inferring the internal structure from overall thickness.
Can a sample settle every performance question?
A sample can establish appearance and fit. Performance acceptance needs the relevant design requirements and agreed verification method.
