Abstract

In order to improve the toughness of glass fiber (GF) reinforced unsaturated polyester resin (UPR), low molecular weight polyisobutylene (LPIB) was selected as the toughening agent. Considering its poor thermal compatibility with UPR matrix, LPIB was first grafted by two small molecular compounds, named maleic anhydride (MAH) and glycidyl methacrylate (GMA) through the novel solvothermal method which was developed in our laboratory. And then, all of these three kinds of low modulus elastomers, including LPIB, MAH grafted polyisobutylene (LPIB-g-MAH) and GMA grafted polyisobutylene (LPIB-g-GMA) were selected to modify GF reinforced UPR (GFRUP) composites. According to the results, incorporation of small amounts of grafted LPIB contributed greatly to the improvement of the toughness of GFRUP composites because of the high flexibility of the molecular chain without obviously influencing other primary properties. Moreover, 4 wt% of elastomer was an optimal amount for promoting the mechanical properties of GFRUP composite. Compared to other liquid rubbers, LPIB-g-GMA had the best toughening effect due to its stronger effect of GMA on UPRGF system. In addition, the impact strength of the modified GFRUP composite was improved up to 2.3 order of that of the unmodified GFRUP composites when 4 wt% LPIB-g-GMA was added. Consequently, LPIB-g-GMA could be employed as an effective toughening agent to GFRUP system. The toughening mechanism, thermal behavior, thermal stability and morphology of GFRUP composite are also discussed. The morphology analysis further proved the increase in toughness through the addition of grafted LPIB.
