摘要: Glass fibers grafted by hyperbranched polymer with amino terminal group, GFs-HBPA, were incorporated into an epoxy matrix to prepare a high-performance composite. Mechanical characterization of epoxy-based composites was performed investigate the effect GFs-HBPA in matrices. The revealed significant improvements flexural strength, elongation at break, and tensile as well impact resistance comparison neat epoxy. For instance, strength for composite 2 wt% increased by about 17.7, 158, 7.9, 35.9 %, respectively, relation reinforcing analyzed on fracture surface through field emission scanning electron microscopy.
