Investigation on Fabrication of Glass Fiber Reinforced Polypropylene by Recycled FRTP and their Properties

Abstract:

In this paper, glass fiber reinforced polypropylene composites have been successfully fabricated via double screw extrusion by using mechanical crushed leftover materials as the raw materials with maleic anhydride grafted polypropylene (PP-g-MAH) and γ-ammonia propyl-triethoxy silane (KH-550) as the compatilizer and coupling agent, respectively. The influences of the contents of PP-g-MAH and KH-550 on the micro-structures and crystallization as well as mechanical properties of the fabricated composites have been systematically investigated. The results showed that: the recycled raw materials were homogenously dispersed in the polymer matrix without obvious agglomerations; with adding the recycled raw materials and compatilizer, the crystallization behaviors of PP did not changed dramatically while their thermal stabilities were greatly improved; the tensile strength of the product increased by 14% while notched impact strength increased by 21% as the contents of PP-g-MAH and KH-550 were 10phr and 1phr, respectively.
