| Abstract Scope |
In space exploration, lightweight multifunctional materials that shield neutron radiation, dissipate heat and provide damping are essential. Polymer composites with one-dimensional (1D) boron nitride nanotubes (BNNT) and two-dimensional (2D) boron nitride nanoplatelets (BNNP) offer promising solutions due to their distinct neutron radiation shielding, thermal, and damping properties. This study aims to understand how these 1D and 2D morphologies influence the performance of high-temperature (HT) epoxy composites. We developed ultralightweight, three-dimensional boron nitride foams, including BNNT and BNNP, via freeze-drying. These foams were then infiltrated with HT epoxy to form dense BN foam-polymer composites. The neutron radiation shielding properties were measured using indium foil radioactive decay tests. Thermal properties were characterized via Flash Diffusivity whereas mechanical properties were evaluated through in-situ nanoindentation. These BN nanomaterial composites offer promising potential for developing high-performance, tailorable composites for demanding environments. |
