The invention of the phosphate glasses (P-glass) made the development of new polymer-glass composites possible. However, previous attempts to develop polypropylene/P-glass composites were unsuccessful. Only P-glasses with a very low T_g could be used because of the relatively low processing temperature of polypropylene. The applications of these materials were limited due to the poor durability of the glass. In this work, novel stabilizer systems for polypropylene were utilized to elevate the processing temperature so that a much more durable P-glass could be used. Comparison studies between P-glass and E-glass reinforced composite systems were also performed.
