Composite compression moulding already produces components that can combine strength, heat resistance and dimensional stability. It’s an established process, so its future will come from producing more complex parts faster, controlling quality more closely and making better use of materials.
For you, that could widen the range of components and production volumes for which compression moulding makes commercial sense. It will also make early decisions about material, design and end-of-life treatment more important.
Could faster compression moulding cycles support higher production volumes?
Curing time has traditionally limited the rate at which manufacturers can produce thermoset composite parts. Material and equipment developers are now working on rapid-cure resins, automated charge placement and faster handling. For example, the National Research Council Canada’s SNAP Composites programme is targeting cycle times of less than two minutes for RTM-compression and prepreg-compression processes.
Of course, this won’t mean every component can leave the mould in two minutes. The cycle time will always be determined by the specific material, thickness, geometry and performance requirements. However, these developments could make compression moulding more cost-effective at higher volumes while retaining its advantages for large or structural parts.
Are EVs more dependent on composite compression moulding?
As battery-powered equipment becomes more common, manufacturers will need a wider range of specialist parts. This is particularly true in automotive component manufacturing, where EVs introduce new performance requirements.
Components around an EV battery or high-voltage system may need to minimise weight while providing some combination of electrical insulation, heat resistance, impact protection and flame or thermal-runaway containment.
These requirements can make compression-moulded thermoset composites suitable candidates, depending on the application. They could be used to create composite battery covers, underbody panels, electrical barriers, power-electronics housings and structural supports. One example is the UK’s ELEVATION project, which is developing production-ready compression-mouldable composites and modular tooling for 800-volt traction battery packs.
This doesn’t remove the need for application-specific development and validation, of course. No composite automatically satisfies every requirement. A battery enclosure may also need electromagnetic shielding, controlled heat transfer and verified crash performance.
Could hybrid reinforcement create more integrated compression-moulded parts?
One developing method places rapid-cure prepreg and local discontinuous-fibre material in the same compression mould. The prepreg reinforces the main structure, while the discontinuous-fibre material helps form ribs and areas of different thickness.
NRC Canada’s SNAP Hybrid programme is developing this method to create complex components that require little further shaping. Combining these features in one moulding cycle could reduce the number of separate pieces that manufacturers must produce and join.
Hybrid reinforcement isn’t new. However, current development focuses on faster-curing materials, automation and process control that could make the method suitable for more production applications.
How could digital process control improve compression moulding quality?
Compression moulding has long depended on simulation, in-mould sensors and statistical processes. What’s developing is the integration of their data with digital models that can predict cure state, fibre orientation or component performance during production.
Advanced systems can already identify changes in pressure or temperature. The next step is predicting whether those changes will affect part quality, then using that information to guide inspection or process adjustments.
For you, this could mean faster development, more targeted inspection and better evidence that each production batch followed the approved process.
How could reprocessable composites improve end-of-life options?
The technology to recycle and reprocess fibres and thermoplastic composites in compression moulding has been around for some time. Current development work focuses on preserving more of the recovered fibres’ length and performance while creating feedstocks that produce consistent moulded components.
Commercial recycling routes already exist for carbon and glass-fibre composites. However, supply chains remain limited and recovered fibres may be shorter. You must therefore verify that a recycled compound still meets your component’s requirements.
Thermoplastic composites can be reheated and reprocessed, potentially providing more end-of-life options. However, they won’t replace thermosets in every application. In most cases, thermosets should still be chosen where you need heat resistance, dimensional stability or electrical insulation. Our thermoplastic and thermoset comparison explains these trade-offs.
Material developers are also developing thermoset composites that can be repaired or reprocessed. In July 2026, Teijin announced a developmental carbon-fibre thermoset that can be repaired with heat, remoulded through compression moulding and chemically separated to recover its fibres. Samples aren’t planned until 2028, but the project shows how future materials could combine thermoset performance with improved repair and recycling options.
How can you prepare your next compression-moulded component?
You don’t need to wait for new resin systems or fully automated factories. The decisions that prepare a component for the future already make commercial sense.
Define your part’s mechanical, thermal, electrical and fire requirements before choosing a material. Consider whether one moulding could replace several assembled pieces. Establish your production volume, traceability needs and end-of-life priorities early enough to influence the design.
At Talisman Group, we support you from material and process selection through component design and tooling to production. Talk to us about developing a compression-moulded composite component that balances performance, cost and long-term manufacturing requirements.
