Core Material Categories
Core materials play a vital role in composite structures by providing thickness and rigidity without significantly increasing weight. Used in sandwich construction, these materials are placed between two composite skins, enhancing stiffness, impact resistance, and load-bearing capacity. Whether you’re building boats, wind turbine blades, automotive parts, or architectural panels, the right core material can dramatically improve strength-to-weight performance. We offer a wide range of high-quality core solutions to meet the structural and processing demands of various industries.
Advantages of Core Materials
- Increase structural rigidity without adding excess weight
- Improve impact resistance and fatigue performance
- Reduce overall material costs by minimizing resin usage
- Enable design flexibility with various shapes and densities
- Ideal for lightweight, high-strength applications in demanding environments

Core Mat
Resin-absorbing mat that adds bulk and stiffness in laminates.
- Ideal for reducing print-through and improving surface finish.

Balsa Wood
Natural, high-strength core with excellent shear properties.
- Lightweight and biodegradable; suitable for marine and wind energy sectors.

PVC / PET Foams
Closed-cell foam cores with consistent density and performance.
- Resistant to moisture, chemicals, and impact; easily shaped or machined.

Honeycombs
Ultra-lightweight core with superior stiffness-to-weight ratio.
- Common in aerospace and high-performance structural applications.

Core Bonding Paste
Thixotropic adhesive used to bond core materials to composite skins.
- Provides strong adhesion, gap filling, and resistance to delamination.
