Structures and properties of HMPBO fibers treated by oxygen plasma/polyhedral oligomeric silsesquioxane
Source abstract
Abstract
The surface of high modulus poly(p‐phenylene‐2,6‐benzobisoxazole) (HMPBO) fibers were treated by the combination method of oxygen plasma/polyhedral oligomeric silsesquioxane (POSS). The chemical compositions and surface morphologies of HMPBO fibers were characterized by Fourier transform infrared, X‐ray photoelectron spectroscopy, thermogravimetric analyzer, and scanning electron microscopy. The interfacial shearing strength (IFSS) of the HMPBO/cyanate ester (HMPBO/CE) micro‐composites was measured by single fiber pull out test. Results showed that the POSS was grafted on the surface of HMPBO fibers, and the grafting amount was about 0.82 wt%. After the treatment, the HMPBO fibers became coarser and the diameter was also increased. Compared with that of pure HMPBO/CE micro‐composites, the IFSS of treated HMPBO/CE micro‐composites was increased by 20.7%. POLYM. COMPOS., 34:2026–2030, 2013. © 2013 Society of Plastics Engineers
