Composite sandwich structures refer to multi-layer constructions that combine a lightweight core with high-strength composite skins to create superior stiffness, durability and flex control. The core provides thickness and rigidity with minimal weight, while the outer skins manage load distribution, impact resistance and torsional stability.
Their behaviour depends on core material properties, reinforcement choices such as fiberglass or carbon fibre, the resin system, and how the laminate schedule controls flex pattern, torsion and long-term durability.
Composite sandwich performance traits
- High stiffness-to-weight ratio
- Improved impact and dent resistance
- Refined flex tuning for performance
- Greater durability under heavy use
Composite sandwich structures are widely used in modern surfboard engineering to increase performance longevity, reduce pressure dents and provide a crisp, responsive feel.
Shapers refine sandwich constructions through tuned layer transitions, material choices and resin optimisation to maintain responsiveness, feedback and structural integrity.
