What the Composite Digital Passport is

At its core, the passport is a trusted, long-lived digital record tied to a physical composite asset.

It is built on four simple ideas:

1. Every relevant material, batch, or part has a unique identity
   Using globally recognised standards such asISO/IEC 15459 and GS1 identifiers ensures items are uniquely identifiable across companies and decades, without relying on a central registry.
2. The physical part is cryptographically bound to its digital record
   Secure NFC or RFID tags raise the bar against cloning, replay attacks, and identifier spoofing, providing confidence that “this record belongs to this thing”.
3. Legitimacy is established by commissioning, not paperwork
   A digitally signed commissioning event binds the identifier, tag, manufacturer, model, and time of introduction into the ecosystem. This creates strong audit and dispute evidence while remaining operationally lightweight.
4. Data is shared by purpose, not by default
   Different actors see what they need to answer their questions, not raw data dumps. Summary answers (“Is this resin acceptable?”, “Was this part made within spec?”) can be trusted without exposing sensitive process details.

Why this matters

For OEMs

OEMs need confidence without friction.

The passport provides:

• Faster acceptance of incoming parts through trusted commissioning and manufacturing process evidence.
• Early warning of supply-chain risk, such as delayed batches, missing custody events, or anomalous behaviour.
• Reduced audit and certification effort, with machine-readable, event-based records suitable for regulators, insurers, and customers.
• Lower exposure to counterfeit and substituted parts, using defence-in-depth fraud controls rather than single checks.

The result is fewer surprises, faster decisions, and less expensive firefighting.

For parts manufacturers

Manufacturers need proof, not paperwork.

The passport enables:

• Automatic capture of manufacturing evidence (e.g. cure temperatures, vacuum levels, storage conditions) as witnessed data rather than retrospective claims.
• Clear demonstration of conformance without sharing proprietary recipes or full datasets.
• Simpler dispute resolution, with signed, time-stamped events showing what happened, when, and by whom.
• Trusted repair, rework, and re-certification, preserving part identity and value over its life-cycle.
• Ease of communicating your process information (through automation). You increase trust but keep your secrets.

This reduces scrap, shortens lead times, and protects reputation.

For raw-materials suppliers

Material suppliers need assurance without over-exposure.

The passport supports:

• Batch-level traceability tied to downstream parts without leaking customer relationships.
• Clear answers to “is this material safe to use?”, including shelf-life, storage compliance, and batch testing status.
• Reuse of existing data, linking to REACH, SVHC, and environmental records rather than duplicating them.
• Trusted roll-ups, where thousands of internal data points become a single defensible statement higher up the supply chain.

This turns data into a commercial asset rather than a liability.

Reducing fraud risk by design

Composite supply chains face real adversarial threats: cloned identifiers, grey-market tags, illegitimate first sightings, and insider misuse. No single control is sufficient.

The passport architecture therefore adopts a defence-in-depth model, combining:

• Secure physical–digital binding,
• Signed commissioning events,
• Authorised channels and operational rules,
• Privacy-preserving anomaly detection,
• Ecosystem-level risk scoring.

This approach reduces both the likelihood and impact of fraud while remaining usable at industrial scale

Why we are asking for your input

We are not building this in isolation.

Composites have unique requirements that generic Digital Product Passports do not fully address:

• Part-level lifecycles,
• Repairability,
• Process sensitivity,
• Confidentiality,
• Complex supply chains,
• and long service lives.

Before moving further, we want to validate priorities with the people who will live with the outcome.

We are therefore inviting OEMs, parts manufacturers, and raw-materials suppliers to take part in a 45-minute structured interview to help us understand:

• Which questions you most need the passport to answer.
• Where time and money are currently being lost?
• What level of assurance is “enough” in practice?
• Where confidentiality boundaries must sit?
• What would make adoption easy rather than painful?

This is not a sales call. It is a design conversation.

Your input will directly shape requirements, architecture choices, and how value is delivered across the ecosystem.
