Lantor Soric, Coremat XM, Xi, XF & XM: The Complete Guide to Composite Core Materials
Choosing the right composite core material is one of the most important decisions when designing lightweight, high-performance composite structures.
Whether you’re manufacturing boat hulls, vehicle components, architectural panels, or industrial mouldings, selecting the correct core material can help reduce weight, improve stiffness, optimise resin consumption, and enhance surface finish quality.
Lantor’s range of advanced composite core materials—including Soric®, Coremat XM®, Xi®, XF® and finish tissues—has become a preferred choice across marine, transport, construction and industrial sectors because of its ability to simplify manufacturing while delivering exceptional mechanical performance.
In this guide, you’ll learn:
- What Lantor composite core materials are
- The differences between Soric, Coremat XM, Xi and XF
- Which product suits specific applications
- Benefits for resin infusion and hand lay-up processes
- How to choose the best material for your project
What Are Composite Core Materials?
A composite core material is placed between reinforcing layers to increase stiffness and thickness while minimising weight.
Rather than using additional layers of reinforcement and resin—which can increase weight and manufacturing costs—core materials create stronger, lighter structures with improved performance.
Key Benefits of Core Materials
- Increased stiffness-to-weight ratio
- Reduced overall laminate weight
- Better resin distribution during infusion
- Improved thickness control
- Enhanced surface quality
Lower material consumption and production costs
These advantages explain why composite cores are widely used in industries ranging from boat building and transportation to renewable energy and construction.
