“…Reports have shown that the intercourse of filler particles into fiber‐reinforced matrix have caused an increased elastic modulus with decrement in overall material cost . Such composites having matrix reinforced with both particulates as well as fibers are known as hybrid composites . Their low cost and high strength to weight ratio have found huge number of engineering applications.…”

In this research article, the mechanical analysis and microstructure investigation of chicken feather fiber with carbon residuum (CR) (obtained from crumb rubber) fused with epoxy resin hybrid composite has been done. The fibers surface was alkali treated with caustic soda (sodium hydroxide) to improve the interfacial bonding with matrix and reinforcement. Herein, the composites were fabricated using the hand lay‐up technique. Chicken feathers in form of reinforcing fibers were taken in various weight percentages of 1, 3, 5, and 7. Various mechanical tests were performed in accordance with the ASTM standards, and it was perceived that the 5 weight percentage of chicken feathers recorded the optimum impact test results. Finally, the hybrid composites were fabricated with this weight percentage of feathers and varying weight percentages (0.5, 1, 1.5, 2, and 2.5) of CR. Mechanical testing was then conducted on these hybrid composites and determined that the tensile strength, flexural strength and impact strength showed a substantial enhancement. The justification of this enhancement was provided through the microstructural tests that includes the scanning electron microscopy and X‐ray diffraction analysis. Best results were forecasted for 5 wt% chicken feather and 1 wt% of CR hybrid composites amongst various combinations tried. Thus, noteworthy improvement in case of hybrid composite was seen as compared with neat epoxy. POLYM. COMPOS., 40:2690–2699, 2019. © 2018 Society of Plastics Engineers

“…It must be mentioned that clusters appear in the specimen due to the granulated pultruded fiber strand. These clusters can have a negative effect on mechanical performance [ 26 ]. The GF reference shows one of these clusters on the surface, with green colored fibers showing an orientation of about 45°.…”

Pultruded Hybrid Reinforced Compounds with Glass/Cellulose Fibers in a Polybutylene Terephthalate Matrix: Property Investigation

2022

The fiber type, orientation of the fiber, fiber-matrix adhesion, and the fiber length are very important for the performance of a short fiber reinforced plastic. Hybrid reinforced polybutylene terephthalate and reference compounds were tested using tensile, Charpy impact, and three-point bending mechanical tests. The interaction of regenerated cellulose fiber and glass fiber was investigated using a polybutylene terephthalate matrix at a fiber volume content of 10%. The ratios of each fiber type was varied. The compounds were pultruded with an extrusion die to have an even fiber length of 3 mm after granulating. In a second step, the specimens were injection molded for mechanical testing. The results were compared to the rule of hybrid mixtures (RoHM) prediction. It was shown that the results of the hybrid reinforced compound were close to the RoHM prediction. The Charpy impact tests show a high positive hybrid effect. The fiber length shows an interaction that is dependent on the ratio of each fiber type.

“…In the RCF reference compounds, it can be noted that a lower RCF content leads to higher elongations at break. This can be explained by the reinforcing effect of the fiber [ 21 ]. A higher content of fiber in the polymer leads to brittleness of the material, which is reflected in a reduction in elongation at break [ 22 , 23 ].…”

Influence of Fiber Volume in Hybrid Short Glass/Cellulose Reinforced Thermoplastic Compounds

Glass fibers (GF) and regenerated cellulose fibers (RCF) are possible partners in the hybrid reinforcement of thermoplastics because of their different properties. Due to the weak bonding properties of polypropylene, coupling agents are used and the fiber volume content is set high to achieve high reinforcing effects. A lower fiber content of GF can raise the toughness properties of a reinforced polypropylene which is investigated in this study with different ratios of GF and RCF. The composites are tested in tensile tests, flexural tests and also in notched Charpy impact tests. The results can be used to compare whether a substitution of GF with RCF or the addition of more GF leads to higher mechanical properties. The tensile and Charpy impact results are compared with the Rule of Hybrid Mixtures (RoHM) to show the deviation to the prediction. Better results in terms of stiffness and strength are seen with a higher total fiber volume, while hybrid reinforced specimens show lower toughness values compared to the RCF reinforced reference specimens. Adding 5 vol% GF to 16 vol% RCF results in an increase in tensile strength by 26%, but also a significant decrease in elongation at break by 65%.
