Composite & Carbon Fibre Inspection for Automotive Manufacturing

Supporting Automotive Development from Prototype to Production

How integrated metrology is improving composite tooling, production quality and structural confidence across the automotive manufacturing process.

Introduction

Composite and carbon fibre inspection has become an essential part of modern automotive manufacturing as manufacturers increasingly adopt lightweight materials to improve vehicle performance, efficiency and sustainability.

Carbon fibre composites can deliver significant weight reductions compared with traditional metal structures while maintaining exceptional strength and rigidity. However, unlike machined components, composite parts are heavily influenced by tooling accuracy, material lay-up, curing behaviour and process variation, making dimensional control significantly more challenging.

As a result, inspection has evolved far beyond a final quality check. It now plays a critical role throughout the engineering lifecycle, helping manufacturers validate designs, optimise tooling, improve production processes and maintain confidence in every component they produce.

Designing for Manufacture

Successful composite manufacturing begins long before the first component is produced.

During the design stage, engineers must consider not only performance, but also how a component will be manufactured, assembled and inspected. Identifying potential design issues early helps reduce downstream rework, minimise tooling modifications and accelerate product development.

Digital engineering solutions such as Cognitive Design by CDS support this process by enabling engineers to analyse and optimise component designs before manufacture begins. Combined with accurate measurement data, they help ensure that design intent can be translated into practical, manufacturable composite components.

By validating geometry at the earliest stages, manufacturers reduce development risk before production begins. This early verification helps minimise tooling changes, shorten development times and improve confidence that design intent can be successfully translated into manufacturable composite components.

Building Accurate Composite Tooling

The accuracy of every composite component starts with the tooling used to manufacture it.

Moulds, fixtures and trimming tools must all be produced and validated to a high degree of accuracy, as even minor dimensional deviations can be replicated across every part manufactured.

This approach has delivered measurable benefits in real-world applications. During our work with Dash-CAE, portable 3D scanning was used to validate large composite moulds, 3D printed tooling and first-off parts, helping improve inspection efficiency while providing the detailed measurement data needed to support high-quality composite manufacture.

Portable Metrology

Portable metrology enables engineers to inspect large tooling quickly and accurately, directly on the shop floor, reducing delays and providing immediate feedback during manufacture.

CMM Validation

Where tighter tolerances or critical interfaces require verification, CMM inspection provides the high levels of precision and repeatability needed to validate tooling before production begins.

Laser Projection with Virtek

Laser projection systems such as Virtek further improve manufacturing efficiency by projecting ply boundaries, trim lines and assembly locations directly onto tooling. This reduces reliance on physical templates, improves repeatability and helps minimise operator error during composite lay-up.

Together, these technologies provide confidence that tooling is ready before the first production component is manufactured.

Supporting Composite Manufacture

Composite manufacturing presents challenges rarely encountered with traditional materials.

By integrating inspection throughout the manufacturing process, engineers gain valuable feedback on how tooling, material behaviour and curing cycles influence final component geometry. This allows manufacturing processes to be refined before variation becomes a costly production issue.

Material behaviour during lay-up and curing can introduce spring-back, distortion and dimensional variation that affect both fit and structural performance.

Monitoring Dimensional Stability

Portable metrology allows engineers to rapidly compare manufactured components against CAD models, identifying dimensional variation early and providing valuable insight into how manufacturing processes influence final geometry.

Automating Inspection

As production volumes increase, automated inspection workflows help maintain consistency by reducing manual intervention and providing repeatable measurement throughout manufacture.

Rather than identifying issues at the end of production, integrated metrology enables manufacturers to monitor quality continuously throughout the manufacturing process.

Verifying Structural Confidence

As components move towards validation and production, inspection requirements become increasingly focused on ensuring dimensional accuracy and structural confidence.

Different measurement technologies each contribute unique strengths.

Portable Metrology

Captures complete surface geometry of large or complex composite components quickly and efficiently.

CMM Inspection

Provides high-precision validation of critical interfaces, functional features and tolerance-sensitive areas.

Industrial CT Scanning

Industrial CT scanning complements traditional composite inspection by enabling manufacturers to inspect internal features that cannot be accessed using conventional measurement methods.

This makes CT particularly valuable for identifying:

• Internal voids
• Delamination
• Bonding integrity
• Internal geometries
• Manufacturing defects

Selecting the appropriate inspection technology ensures manufacturers obtain the level of measurement confidence required for each stage of production without introducing unnecessary complexity. Combining complementary technologies often provides the most efficient route to complete component validation.

Supporting Assembly and Production

Inspection does not end once components leave the quality department.

Composite parts must continue to fit consistently throughout assembly, ensuring they integrate accurately with neighbouring components while reducing unnecessary rework.

Mixed Reality with Twyn

Mixed reality solutions such as Twyn by Visometry allow operators to compare physical components directly against digital CAD models in real time.

By overlaying digital information onto physical parts, Twyn supports:

• Assembly verification
• Digital work instructions
• Quality inspection
• Reduced rework
• Faster production decisions

This enables manufacturers to bring digital quality assurance directly onto the shop floor.

Driving Continuous Improvement

One of the greatest advantages of integrated metrology is that inspection data does more than verify finished components.

It creates a continuous feedback loop between design, tooling, manufacturing and quality.

Measurement data can be used to:

• Refine tooling
• Improve manufacturing processes
• Optimise component designs
• Reduce variation
• Support future development programmes

Rather than simply identifying defects, integrated metrology creates a continuous improvement cycle that enables manufacturers to refine tooling, optimise production processes and enhance future product development programmes. As products evolve, measurement data becomes an increasingly valuable engineering

Real-World Automotive Applications

Measurement Solutions has supported a wide range of automotive and advanced engineering organisations working with composite materials throughout the product lifecycle.

For example, our collaboration with Dash-CAE demonstrated how portable 3D scanning can support composite tooling, additive manufacturing and first-off inspection. By implementing the Creaform HandySCAN Black, Dash-CAE was able to accurately inspect large composite moulds, 3D printed tooling and first-off components, improving inspection efficiency while supporting reverse engineering and manufacturing quality. The solution also enabled accurate scanning of reflective aluminium moulds and complex composite geometries that were difficult to capture using previous inspection methods.

Similarly, our work with TripleR Composites demonstrated how advanced metrology supports tooling validation and manufacturing accuracy, while our collaboration with RML Group highlighted the role of integrated measurement technologies in accelerating vehicle development and engineering validation.

Although every project presents different challenges, they all reinforce the same principle:

The greatest value comes not from individual technologies, but from applying the right measurement capability at the right stage of the engineering process.
