Properties analysis of novel composites for space robots

Basing on modeling analysis of kinematics and dynamics of the innovational spacecraft-space robots, increasingly complex space operations require the advanced composites to have excellent mechanical properties at high frequency. The novel powdery nitrile butadiene rubbers (P-NBRs) are performed to fabricate the P-NBRs/cyanate esters (P-NBRs/CE) and P-NBRs/glass fiber/CE (P-NBRs/GF/CE) composites. Results show that the flexural and impact strength of the P-NBRs/CE composites are increased firstly, but decreased with the excessive addition of P-NBRs. The heat resistant properties of the P-NBRs/CE composites are decreased with the increasing addition of P-NBRs. However, the mechanical properties of P-NBRs/GF/CE composites are decreased with the increasing addition of P-NBRs. The dielectric constant and dielectric loss of the P-NBRs/GF/CE composites are increased with the increasing addition of P-NBRs. POLYM. COMPOS., 35:564-569, 2014.
