Fiber reinforcement in polymer matrix contribute significant role in improving mechanical and tribological behavior of any composite for friction application. Hence such composites are developed by selecting suitable matrix and reinforcement materials. In the present study three frictional composite materials were prepared by varying basalt fiber, aramid fiber and hybrid of both theses fibers. Namely Basalt Fiber reinforced composite (BFRC), Aramid Fiber reinforced composite (AFRC) and Hybrid of these fibers reinforced Composite (HFRC), with polyimide matrix. The other ingredients were mixed in constant proportions to enhance the frictional property of the composites and specimens were prepared using hot compression molding machine. The pin-on-disc testing was carried out with different loading condition of 20, 30 and 40 N and varying sliding velocities of 150, 200 and 250 rpm to understand the effect of these parameters on coefficient of friction and the wear rate of specimens. Based on results, contour were developed using Minitab software. HFRC shows the best tribological characteristics compared to BFRC and AFRC. The contact temperature is less for HFRC due to the good heat conduction by hybrid fibers. The thermal stability and the degradation of composites were study from Differential scanning calorimetry (DSC) and Thermogravimetric Analysis (TGA) respectively. It is observed that HFRC has better thermal stability. The Scanning Electron Microscopy images shows better bonding of matrix and fiber for HFRC compared to other composites and various mechanisms were identified along the wear regime areas.

“…Moreover, mechanical properties such as hardness, flexural strength and Young modulus of the composites can be improved with introduction of micro, -nano fillers to the epoxy matrix, respectively [43][44][45][46][47][48][49][50][51][52][53][54][55]. Whereas, nano-fibres/particles are more effective than that of micro-fibres/particles.…”

Effects of nano-Al 2 O 3 and PTFE fillers on tribological behaviour of basalt fabric reinforced epoxy composite (BFRC) produced with a combination of molding and mixing method were studied by Taguchi L9 design. Microstructures and worn surfaces of composites were investigated by scanning electron microscopy. Regression equations were also developed for predicting wear and coefficient of friction. The results indicated that specific wear rate increased with increasing load and decreasing speed, but friction coefficient decreased with increasing speed, PTFE addition and medium load. In addition, wear rate of nano-PTFE was lower than that of nano-Al 2 O 3 because of its microstructure. PTFE decreased the friction about 17%. Load was effective on the wear rate while speed was dominant on the friction. Moreover, multiple fiber fractures and large numbers of debris were dominated for BFRC while fiber debondings, fiber removals and debris agglomerations were effective for Al 2 O 3 , but fiber fractures and flake types of debris were responsible for PTFE.

“…Most commonly, such PP is used in various applications such as furniture, textile, building materials, medical instruments, medical packing, and automobile parts. 10–12 The addition of fibers in the polymer matrix enhances the physical, mechanical, and chemical properties of the composites, thereby enhance their performance. The need for more efficient composites with enhanced mechanical and thermomechanical properties for various applications results in the replacement of currently used materials.…”

In this work, the wear loss of basalt fiber reinforced polypropylene/polylactic acid polymer composite was analyzed using pin-on-disc under dry sliding conditions. The polypropylene, polylactic acid, and basalt fiber (chopped fiber) are melted and mixed homogeneously using a twin-screw extruder, which is followed by an injection molding technique for specimen preparation. The specimens are named as PPB1 (polypropylene, 50%; polylactic acid, 35%; basalt fiber, 15%), PPB2 (polypropylene, 55%; polylactic acid, 30%; basalt fiber, 15%), and PPB3 (polypropylene, 60%; polylactic acid, 25%; basalt fiber, 15%) based on their weight fraction. The wear rate and coefficient of friction are measured for each sample subjected to three different loads and sliding velocities. It is observed from the wear mapping that the wear loss of sample PPB3 is relatively less when compared with the other samples. The scanning electron microscope images of the worn-out region of the sample reveal the fracture and dislocation of fibers in the matrix. The sample PPB3 shows low wear loss. It is due to the better cohesion between the fiber and the matrixes when compared with the other samples.
