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. © 2013 Society of Plastics Engineers
