You are preparing polypropylene (PP)/glass fiber composites and have decided to improve the fiber-matrix interaction by modifying the fiber surface with a compatibilizer. 2 types of maleated polyolefins (i.e., maleated polypropylene and maleated polyethylene) are available in your laboratory. Table 1 shows some physical properties of the compatibilizers. Table 1. Physical properties of compatibilizers. a. Identify which compatibilizer you would use and explain why. b. Illustrate the reaction between the compatibilizer and the glass fiber. c. Illustrate the hypothetical fiber-matrix interface of the composite. d. Briefly explain the adhesion mechanism between the modified glass fiber and the PP matrix
