Composite Quality Control: Planning Sample Acceptance

Accepting a composite sample should involve more than deciding that it looks right on delivery day. For a cabin body, panel, enclosure or decorative component requested from MOE Composite, the inspection brief can begin with the quotation. Agreeing on what will be checked, and how, gives both parties a clearer basis for the sample review.

Identify the critical characteristics

Different areas of a component may need different acceptance criteria. Fixing holes can be critical to installation while a free edge has a separate visual requirement. Mark the important dimensions, measurement references and units on the drawing. Project-specific tolerances should be agreed from the application requirements, not assumed from a catalogue photograph.

A starting point for the inspection plan

Check	Information to supply	Acceptance record
Mounting dimensions	Revision-controlled drawing and measurement references	Measured values and assessment
Interface fit	Mating component, fasteners and trial scope	Installation trial notes
Visible finish	Colour/gloss reference, viewing distance and lighting	Assessment against the reference
Delivery scope	Component list, quantities and included accessories	Item-by-item delivery check

This table is a planning template, not a certificate or a test result. If the application requires additional testing, agree the method, sample quantity, acceptance limit and responsibility for the report within the project scope.

Describe observations precisely

A visible scratch, an offset hole and a gap during assembly are different observations. Record the location and inspection conditions rather than grouping them under a single “quality issue”. A scale in a photograph can help explain the observation, but the photograph does not replace the relevant measurement record.

Keep sample approval tied to a revision

When a hole moves, an edge is trimmed differently or the surface finish changes, update the applicable reference. A verbal agreement is difficult to trace during a repeat order. The sample label, drawing revision and approval note should identify the same configuration. Record which aspects of the previous approval remain valid and which require review.

Include packing and receipt in the plan

Discuss how the component will be supported during transport and how visible surfaces will be protected. For a multi-part delivery, match package labels to the component list. If damage or a discrepancy is found, retain the part identity, delivery date and clear photographs so that the issue can be investigated without losing context.

For export projects, state whether approval will take place at the supplier, on receipt or after an installation trial. Include the required inspection documents in the enquiry rather than requesting them after production has finished.

Attach your acceptance plan when requesting a quotation from MOE Composite. If the material and supply boundaries are still unclear, start with the FRP and fiberglass enquiry guide. An effective review depends on knowing exactly what the sample was intended to demonstrate.
