Syntactic Cores, Radomes & Mission-Critical Lightweight Structures
When grams equal fuel, and fuel equals range — engineered spheres deliver both.
Syntactic foam cores for sandwich structures, low-dielectric radome and antenna materials, and tooling board for precision master models.
Application scenarios
01
Sandwich panel syntactic cores
High-strength HGM/epoxy cores for interior panels, fairings, UAV structures.
02
Radomes & antenna windows
Low Dk/Df composite skins — HGM lowers dielectric constant toward air (≈1.0) while holding stiffness.
03
Epoxy tooling board
Dimensionally stable, easily machined master and layup tooling boards.
04
Ablative & thermal protection fillers
Hollow cores absorb heat flux in specialty protection systems.
Why switch — on both ledgers
Economic advantages
- Metal-to-composite conversion at commodity tooling cost
- Stable long-lead supply from a 30,000 t/yr single-site plant
- Full traceability and batch COA for qualification programs
Functional advantages
- 30,000 psi grades survive autoclave-adjacent processing
- Low dielectric constant + low loss for RF transparency
- Isotropic CTE reduces thermal cycling fatigue
- 60 µm-class particles pack densely in thin plies
