Dynamic compression response of self-reinforced polypropylene composite structures fabricated through ex-situ consolidation process

A review of the fabrication methods and mechanical behavior of continuous thermoplastic polymer fiber–thermoplastic polymer matrix composites

“…[53,[152][153][154][155] On the other hand, hot compaction method was also widely used to fabricate self-reinforced PP composites. Among others, [30,[156][157][158][159] Qiao et al, [20] Reis et al, [160] and Imran et al [161] reported the fabrication of selfreinforced twill PP composites with 80% fiber volume fractions by using hot compacted PP composite films, whereas 90% fiber volume fraction for self-reinforced plain weave PP composites was reported by Alcock et al [320,329] With the addition of nanoparticles as reinforcement, self-reinforced PP composites nanomodified by carbon-based particles were also fabricated via hot compaction method. [162][163][164][165] Moreover, fabricating other types of self-reinforced UD and woven thermoplastic polymer composites (e.g., PA, [166] PET, [44,167,168] PLA, [169,170] PMMA, [40,41,[171][172][173] PEEK, [416] etc.)…”

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

“…Therefore, development of industry scale production process (known as ex‐situ consolidation) is mandatory. For instance, Imran et al 28 used a potential mass production technique known as the ex‐situ consolidation process to fabricate SR ‐ PP composite structures. They designed a mold to reduce the manufacturing complexity and fabricated corrugated core from the pre‐consolidated SR‐PP sheets using an ex‐situ consolidation process and subsequently face sheets were coupled with identical family of polymer adhesives to accomplish the greatest recyclability (around 90%).…”

“…In addition, mechanical abrasion was applied on PP sheets to increase the roughness of surfaces through which mechanical interlocks were established between core and face sheets. Due to good interlocks, no separation between core and face sheets was observed after the impact test and this protects structures from catastrophic failure when compared to conventional epoxy composites 28 . In another work, Varga et al explored the applicability of four types of propene‐rich amorphous poly‐alpha‐olefin (APAO)‐grades namely, Vestoplast® 708 (VP‐708), VP‐750, VP‐792, and VP‐888 as matrix materials for the manufacture of SR polymer composites and these matrices have extensively different viscosity and molecular weight.…”

Compared to 120 C processing temperature, the samples VP-750 and VP-792 fabricated at 140 C displayed a better tensile strength of ca.…”

Ultrasonic welding of all‐polypropylene composites

“…Three main methods are generally used for the production of all‐polymer composite materials: hot compaction, consolidation of coextruded tapes, and film stacking . Many papers focus on the mechanical properties of various all‐polymer composites and the consolidation process of the matrix and fiber components . Studies have also confirmed that all‐PP composites can be prepared by injection molding .…”
