Concept explicatif généré par l'IA ; il ne s'agit ni d'une photographie de produit de Litian Yunde ni d'un design validé.
A carbon fiber fabric splice needs a defined role and location in the proposed laminate. Discuss where pieces meet or overlap before moulding, including any visible-face requirement. A visually continuous weave pattern does not prove reinforcement continuity, and an attractive seam cannot replace approval of the construction.
Separate appearance from the laminate design
Ask whether a splice concerns only the visible outer fabric, an underlying reinforcement layer or both. These are different questions. Use the controlled construction information to describe the relevant layer and direction. The responsible designer should decide where discontinuities or overlaps are permitted. This article gives a procurement review structure, not a universal splice length, ply arrangement or structural acceptance rule.
Mark permitted and restricted regions
Identify the proposed splice zones relative to holes, edges, curved regions and attachments. If appearance is important, agree the visible boundaries and viewing condition separately. Do not require a seamless cosmetic appearance that contradicts an approved construction without discussing the conflict. Keep the material direction and part identity on the location map. A photograph may show a surface seam but cannot reliably reveal every internal ply boundary.
Control changes between sample and repeat production
Record the approved construction and any permitted placement variation. If a fabric size or cutting plan changes, review its impact before treating the replacement as equivalent. Keep the sample approval specific: surface appearance, construction review and performance validation should not collapse into one vague sign-off. The supplier should state which construction records or evidence it can provide for the ordered scope.
Example: a large visible cover
A buyer requests a large woven cover with an uninterrupted appearance. The supplier proposes a fabric join because of the available cut size. The project reviews the join location and separately confirms the construction with the responsible designer. The approved surface reference shows what is visible; it is not presented as proof of an unseen laminate arrangement.

Questions posées par les acheteurs
Does matching the weave conceal the structural question?
It may improve appearance, but continuity and construction still require their own review.
Can a supplier move a splice without changing the outline?
The outline alone does not define the laminate. Follow the agreed construction-change process.
