Effects of the addition of short carbon fibers (CFs) on the mechanical, physical, and morphological properties of polypropylene (PP) and woodpolypropylene composites (WPCs) were investigated. Hybrid composites (mix of wood and CFs) were manufactured in a two-stage process, pellet extrusion and samples mold injection with varying amounts of poplar wood fiber (0%, 20%, 30%, and 40%) and CFs (0%, 3%, 6%, and 9%), with and without maleic anhydride grafted PP (MAPP) as a coupling agent. The composites were prepared with extrusion blending followed by injection molding. The samples where then tested for mechanical and physical properties, and fractured surfaces where observed with scanning electron microscopy. The results indicated that the addition of CFs to WPCs improved the tensile and flexural strength and the modulus of elasticity but had only a small influence on elongation at break and impact strength. The density of hybrid composites slightly increased with CFs proportion but their water absorption was not affected. Scanning electron micrographs of the tensile fractured specimens showed improved adhesion of CFs and poplar with the PP matrix in the presence of a coupling agent.

“…Interestingly, the curing peak maximum of the molding compounds evidently shifted to lower temperature with higher amount of graphene loading. The positions of exothermic peaks of 10,20,30,40,50, and 60 wt% of graphene content in benzoxazine molding compound were 218, 212, 211, 209, 202, and 196 C, respectively. The results indicated that graphene might act as a catalyst for oxazine-ring opening reaction thus alleviated the curing condition in terms of energy consumption of the polymerization reaction.…”

“…The graphene-filled polybenzoxazine composites were prepared with graphene loadings of 0, 10,20,30,40,50 and 60 wt% to yield molding compounds. The graphene was firstly dried at 110 C for 24 h in an air-circulated oven until a constant weight was achieved and was then kept in a desiccator at room temperature.…”

“…The T d values of the composites were reported to be in the range of 333 to 353 C. Hence, the T d value of the composite at 60 wt% of graphene content was enhanced by 26 C compared to that of the neat polybenzoxazine, which represented about 8% improvement. This enhancement is attributed to the graphene flakes which act as a gas barrier and can delay the decomposition of volatile products [29,30].…”

This research emphasizes on the development of highly filled graphene-polybenzoxazine composites and investigates thermal, electrical, and mechanical properties of the obtained composites for bipolar plate applications. The composition of graphene loading was achieved to be in the range of 10-60 wt%. The experimental results revealed that at the maximum graphene content of 60 wt% (44.8 vol%) in the polybenzoxazine, storage moduli at room temperature of the composites were considerably enhanced with the amount of the graphene, that is, from 5.9 GPa of the neat polybenzoxazine to about 25

The carbon nanotube (CNT) represents one of the most unique inventions in the field of nanotechnology. CNTs have been studied closely over the last two decades by many researchers around the world due to their great potential in different fields. CNTs are rolled graphene with SP 2 hybridization. The important aspects of CNTs are their light weight, small size with a high aspect ratio, good tensile strength, and good conducting characteristics, which make them useful as fillers in different materials such as polymers, metallic surfaces and ceramics. CNTs also have potential applications in the field of nanotechnology, nanomedicine, transistors, actuators, sensors, membranes, and capacitors. There are various techniques which can be used for the synthesis of CNTs. These include the arc-discharge method, chemical vaporize deposition (CVD), the laser ablation method, and the sol gel method. CNTs can be single-walled, double-walled and multi-walled. CNTs have unique mechanical, electrical and optical properties, all of which have been extensively studied. The present review is focused on the synthesis, functionalization, properties and applications of CNTs. The toxic effect of CNTs is also presented in a summarized form.
