Modification of self-reinforced composites (SRCs) via film stacking process

Abstract

This work presents the mechanical behavior of self-reinforced composites (SRCs) manufactured and modified via film stacking. For modification, interleaved films made of polypropylene (PP), a thermoplastic elastomer and a polyolefin engage were combined in different ways to induce the elastic modifier into the matrix material. The content of modifier was also varied in two ways. First, the films were produced out of a single material and second out of a compound. So, the same content of modifier was implemented in two different ways. It is shown that, in case of this research, only the kind of modifier and the content but not the way of implementation are responsible for the mechanical behavior of SRCs. It is shown that the modification can adjust the tensile strength, tensile stiffness and impact properties in a broad range. It is also shown that different mechanical properties of the composite can be predicted by a regression model that uses the Shore A hardness and the content of modifier.

Development of nanoparticle-filled polypropylene-based single polymer composite foams

“…With their polyolefin segment providing a reliable connection to the reinforcement, these materials can effectively function as the matrix in an SPC. The presence of a polyolefinic segment further enhances their suitability for serving as the matrix of a PP-based SPC [ 12 , 20 ].…”

Self‐reinforced polymer composites: An opportunity to recycle plastic wastes and their future trends

“…Capiati and Porter 12 were the pioneers who first introduced this concept in 1975, using high density polyethylene and name the developed materal as “one polymer composite”. Following them, numerous thermoplastic composites were created using this concept and reported their thermal stability and mechanical strength 13,14 . The concepts of SR in various polymers, as well as their mechanical and thermal properties, were discussed in this review.…”
