CF6799 Molded Basalt Fiber Radome Products

Molded Basalt Fiber Radome Products Description

Molded Basalt Fiber Radome Products are precision-engineered enclosures designed to protect sensitive antenna systems while ensuring minimal signal attenuation. Constructed from basalt fiber-reinforced epoxy composites, these radomes exhibit a low dielectric constant (≤ 4.5) and loss tangent (≤ 0.005) at 10 GHz, ensuring excellent electromagnetic transparency essential for high-frequency applications.

The inherent properties of basalt fibers confer high mechanical strength, with flexural strength reaching ≥ 300 MPa, and exceptional resistance to thermal cycling, accommodating operating temperatures from -55°C to +155°C. The material's low moisture absorption (≤ 0.1%) and compliance with UL 94 V-0 flame resistance standards make it suitable for use in harsh environmental conditions.

These radomes are customizable in thickness (2–10 mm) and surface finish, allowing for tailored solutions that meet specific aerodynamic and aesthetic requirements. The natural basalt gray color can be modified to match system designs, and the smooth surface finish is conducive to various coatings and paints.

1.       Common Preparation Methods

The production of Molded Basalt Fiber Radome Products involves several meticulous steps to ensure optimal performance and quality. Initially, high-quality basalt fibers are treated with silane coupling agents to enhance adhesion with the epoxy resin matrix. The treated fibers are then laid into precision-engineered molds corresponding to the desired radome shape. Epoxy resin is infused into the fiber layup under controlled conditions to ensure uniform distribution and impregnation. The composite is subsequently cured under specific temperature and pressure profiles to achieve the desired mechanical and electrical properties. Post-curing processes may include machining, surface finishing, and application of protective coatings to meet specific environmental and aesthetic requirements.
