The focus of this work was to analyze the effect of weight percentage (wt%) of Polyalthia longigolia seed filler (PLSF) on the wear responses (wear loss and coefficient of friction) of the vinyl ester (VE) matrix composites, using signal‐to‐noise (SN) ratio and analysis of variance (ANOVA) methods. The Polyalthia longigolia seed filler/vinyl ester (PLSF‐VE) composites were produced by compression molding (CM) technique. Scanning electron microscopy (SEM) analysis showed that the PLSF content was homogeneously distributed in the matrix. Pin on disc (POD) wear tester was employed to carry out the experiments. Both SN ratio and ANOVA were performed to determine the process parameters that exhibited lower wear responses. The wear of the composite was minimized by optimizing the four diverse process factors: load, P (N), sliding speed, N (rpm) and filler content (wt%), based on Taguchi's L9 orthogonal array. The process parameters at which minimum wear loss (WL) occurred were identified with 25 wt% sample at 10 N and 300 rpm. Also, the process parameters for minimum coefficient of friction (COF) were observed with 25 wt% sample at 5 N and 700 rpm. From the ANOVA results obtained, it was evident that P mostly influenced the WL and COF of the PLSF‐VE composites during POD wear testing. This kind of lightweight composite can be a suitable alternative for small scales loading conditions, such as brake bad and clutch plates in the automobile industry.

“…Tensile and flexural strengths were observed by varying the fiber length, fiber content, and filler content. With fiber content of 25%, fiber length 30 mm and filler content 4% exhibited better tensile strength (23 MPa) and flexural strength (28 MPa) . Yang et al studied the thickness swelling, water absorption, tensile and impact properties of lignocellulosic filler reinforced polyolefin bio‐composites.…”

This article deals with the usage of tamarind seed filler (TSF) as reinforcement in vinyl ester (VE) composites. The composite plates have been fabricated by compression molding machine with TSFs of varying wt% from 5 to 50 as reinforcement material, and their properties such as tensile, flexural, impact, hardness, water absorption, heat deflection tests, and thermogravimetric analysis are studied. The mechanical properties of TSF reinforced VE composites are optimum at 15 wt% filler. The tensile strength and flexural strength of TSF‐VE composites are estimated to be around 34.1 and 121 MPa, respectively. The better impact strength of TSF‐VE composites is found to be 14.02 kJ/m2, and barcol hardness can hold a value up to 42.33. Thermo gravimetric analysis and heat deflection test of TSF reinforced VE composite have improved the thermal stability. The fiber matrix interaction of the fractured mechanical testing specimen has been analyzed by scanning electron microscope. The TSF‐VE composites are used to fabricate the wheel hubcap of heavy‐duty buses, bus seat backrest cover, and silencer guard of the motorcycle. J. VINYL ADDIT.

“…This result can be explained by the load sharing mechanism of the composite material, which varies depending on the matrix-reinforcement interfacial area. When the filler ratio exceeds a certain value, the adhesion strength decreases as the interfacial area increases, as mentioned by Rajamuneeswaran et al 32 Thus, the load is not transferred uniformly throughout the composite sample and flexural strength is reduced. In addition, a proportional increase in flexural modulus of elasticity is observed with increasing Cts filler ratio.…”

In this study, the mechanical and machinability characteristics of chitosan (Cts)-filled polypropylene (PP) composites produced by injection molding method were analyzed. Uniaxial tensile, impact, hardness, and three-point flexural tests were used to observe the influence of Cts filler on the mechanical behavior of PP. For the machinability analysis of these materials, drilling experiments based on Taguchi’s L27 orthogonal array were performed using different drill qualities and machining parameters. Then, machining conditions are optimized through grey relational analysis methodology for machinability characteristics such as thrust force and surface roughness obtained from drilling tests. The results showed that tensile, flexural strength, and percentage elongation decreased while impact strength increased with adding the Cts filler to PP. Moreover, it was determined that the tensile and flexural modulus of elasticity increased significantly and there was a slight increase in hardness. Thrust forces decreased while surface roughness values increased when the Cts filler ratio and feed rate was increased. The optimal machining conditions for minimizing thrust force and surface roughness was obtained as PP/10 wt% Cts material, uncoated tungsten carbide drill, feed rate of 0.05 mm/rev, and cutting speed of 40 m/min. In this regard, PP composite reinforced by 10 wt% Cts is recommended for industrial applications in terms of both the mechanical and machinability characteristics.
