“…Also, the fibers treated with acetic anhydride presented higher thermal stability. The chemical modification of the fibers was also found to ensure a better adhesion of the fibers to the PLA matrix, especially in case of fibers modified using benzoyl chloride which composites exhibited superior mechanical properties …”

“…Luffa sponge‐gourd consists essentially of cellulosic fibers and is derived from Luffa cylindrica plant which is extensively grown is North Africa, among other regions in the world. Luffa fibers (LF) contain 10%‐23% of lignin and 55%‐90% of cellulose which allow them to be used as an effective cellulosic filler presenting biodegradability, large availability, and a relatively lower density compared to several other natural fibers, which permits to attain high loading levels . However, LF is highly hydrophilic and its moisture content could attain a rate of 11%, which might preclude its development as potential reinforcement for hydrophobic polymers.…”

To prepare fully biodegradable materials, variable concentrations of luffa fiber (LF) namely 1, 3, and 5 phr, were incorporated into a poly(lactic acid) (PLA) matrix. To counteract the poor adhesion of the LF to PLA, a compatibilizer which is maleic anhydride‐grafted poly(lactic acid) has been incorporated and the properties of the composites with and without compatibilizer noted, respectively, PLA/LF and PLA/PLA‐g‐maleic anhydride (MA)/LF, were compared. The final torque of PLA/LF was found to decrease with the LF content contrary to that of PLA/PLA‐g‐MA/LF composite which was seen to increase as a result of the interfacial reaction occurring between maleic anhydride groups of the compatibilizer and the hydroxyls of LF. This outcome has been evidenced from the Fourier transform infrared spectroscopy which pointed out the disappearance of the vibration band owing to the anhydride groups of the compatibilizer from the spectra of the PLA/PLA‐g‐MA/LF composite and the better impregnation of LF by the matrix as it has been observed from scanning electron microscopy. Subsequently, the Izod impact strength of the compatibilized composites was seen to increase, especially for 1 phr of LF, whereas the water uptake aptitude was considerably reduced. Also, PLA phase into the composites exhibited lower thermal stability and glass transition temperature compared to pristine PLA.

“…Similarly, one of the most abundant source of waste which also have the potential of replacing costly synthetic reinforcements in polymer matrix composites (PMCs) while improving properties like biodegradability are agricultural wastes. Rice husk, maize stalk, bread fruit shell, eggshell, tropical almond shell, groundnut shell etc have shown to have the ability to not only improve the mechanical properties of polymers but also make them more environmentally friendly while decreasing the cost [6,7,9,10]. Their renewability, low cost due to its abundance and light weight gives them an edge over synthetic filler or reinforcement materials hence the interests from researchers [9,[11][12][13].…”

This work explored the effect of African Walnut Shell Particle (AWSP) (Tetracarpidium conophorum) on the properties of recycled low density polyethylene (rLDPE) composite. rLDPE/ AWSP composite were prepared via compressive moulding techniques using AWSP of sizes 300 and 600μm respectively. Composite design of experiment and analysis of variant (ANOVA) were employed for optimization. Mechanical and morphological analysis of the composite were studied. rLDPE reinforced with AWSP of particle size 300 μm exhibited better tensile strength, modulus of rupture (MOR) and modulus of elasticity (MOE) than those of 600 μm. Morphological analysis showed that uniform distribution of the Walnut shell particulates in the microstructure of the composite is the major factor responsible for the improvement in the mechanical properties. Optimality occurred at a press temperature of 206.465°C, press time of 10 min, press pressure of 7 MPa yielding a tensile strength of 14.082 MPa, MOR of 17.019 MPa and MOE of 755.028 MPa for 300 μm particle sized composite whereas for 600 μm size, it was achieved at press temperature of 199.993°C, press time of 6 min, press pressure of 7 MPa giving a tensile strength of 11.252 MPa, MOR of 15.401 MPa and MOE of 459.531 MPa respectively. The result from the optimization met the standard for interior and exterior mirror casing of automobiles.

Several attempts were made to investigate the effects of various process parameters on the mechanical properties and wear behavior of synthetic and natural cellulosic fibers and also particle-reinforced polymer composites. However, very few studies were carried out on the effects of various process parameters on the mechanical and wear behavior of phenol formaldehyde (PF) composites reinforced with natural cellulosic fibers and particles. Therefore, in the present study, an attempt was made to observe the effects of various process parameters on the mechanical and wear behavior of wood-dust (WD) and coir-pith (CP) particle-reinforced resole-type PF composites. First, the mechanical properties of a WD/PF composite were studied based on the content of CP particles. Then, the erosive-wear behavior of the WD/PF composite was studied with respect to five different parameters such particle content, erodent size, impact velocity, impingement angle, and standoff distance. The erosive experiments were carried out for five different parameters based on the Taguchi experimental design (L27). The results show that the mechanical properties of the WD/PF composite increase with an addition of CP particles. The increment in the composite modulus was higher than that of the composite strength. The erosive test results indicate that the erosion-wear rate is affected by the particle content, impingement angle, erodent size and impact velocity. Brittle-erosion behavior was identified on the surface of the composite with a heavy erosive wear occurring at a 60°impingement angle. Keywords: biowaste particles, phenol formaldehyde, composites, mechanical properties, erosive-wear resistance, Taguchi method Izvedenih je bilo`e kar nekaj poizkusov v zvezi z u~inki razli~nih procesnih parametrov na mehanske lastnosti in obrabo polimernih kompozitov oja~anih s sinteti~nimi in naravnimi celuloznimi vlakni in/ali delci. Toda zelo malo raziskav je bilo izvedenih glede vpliva razli~nih procesnih parametrov na mehanske lastnosti in obrabo fenolformaldehidnih (angl. PF) kompozitov, oja~anih z naravnimi celuloznimi vlakni in delci. Tako je v pri~ujo~em delu predstavljen vpliv razli~nih procesnih parametrov na mehanske lastnosti in obrabo PF kompozitov, ki so bili oja~ani z delci lesnega prahu (angl. WD) in delci kokosa (angl. CP). Te vrste kompozitov se uporabljajo za izdelavo podplatov~evljev. Najprej so bile dolo~ene mehanske lastnosti WD/PF kompozitov glede na vsebnost CP delcev. Sledili so preizkusi in analize erozijske obrabe WD/PF kompozitov glede na vsebnost (koli~ino) delcev v kompozitu, velikost, hitrost in razdaljo u~inkovanja erozijskega sredsta ter njegov vpadni kot. Preizkusi so temeljili na analizi s Taguchijevo metodo (L27) s petimi razli~nimi parametri. Rezultati so pokazali, da se mehanske lastnosti WD/PF kompozitov izbolj{ujejo z dodajanjem CP delcev. Povi{anje modula kompozitov je bilo ve~je od pove~anja trdnosti kompozita. Erozijski testi ka`ejo, da je hitrost erozijske obrabe posledica vseh procesnih parametrov, to je: vsebnos...
