“…The addition of 30% sawdust resulted in better mechanical properties. Similarly, the addition of Indian almond extracted powders improved the tensile and flexural strength of Veli Karuvelam fiber-reinforced polymer composite by about 65 and 240 MPa, respectively, as compared to a neat matrix due to the packing of more high-strength and high-stiffness Indian almond powder as stated by Krishnapillai et al 17 The mechanical properties of the particulate reinforced polymer composite are based on the type, size, and shape of the particles added and the interfacial bonding of the particles with the matrix. Many industrial and agricultural waste particles are also used in the making of particulate reinforced polymer composites.…”

The present work deals with the effective utilization of almond shell bio-waste fillers in the production of vinyl ester polymer composites. The almond shell particle surface was chemically modified by alkaline treatment. The almond shell particles with varying weight percentages of 5%-30% were used to prepare the vinyl ester polymer composite. The experimental results show that a 25% addition of alkaline-treated almond shell particles significantly improved the mechanical properties of the composite when compared to pure vinyl ester and untreated almond-filled composite samples. The highest tensile, flexural, impact strength, and Shore D hardness of the 25% alkaline-treated almond shell composite were 54, 142 MPa, 31, and 79 kJ/m 2 , respectively. This was due to the alkaline treatment of almond shell particles, which improved the interfacial adhesion between the vinyl ester matrix and almond particles. The heat deflection temperature of the 25% alkaline treated almond shell particlefilled vinyl ester matrix composite was 72 C. The thermal insulating characteristics of alkali-treated almond shells were improved due to the reduction of quickly thermal degradable materials such as hemicelluloses and lignin, as indicated by Fourier transform infrared spectroscopic data, and more exposure of minerals to the surface, as confirmed by energy dispersive X-ray analysis. The addition of alkaline-treated almond shell particles improves the characteristics of the vinyl ester matrix and allows the development of biocomposites.

“…Further, the composites showed the least moisture absorption. The strength of Indian almond/Veli Karuvelam natural composite was analyzed by Krishnapillai et al 15 Results indicated that the composites exhibited better mechanical properties.

Natural fiber based composites are gaining increased interest in industrial applications because of less weight, cheap and harmless. In this research work, natural composite was manufactured using Indian almond fiber by conventional hand layup process. The effect of fiber length (10, 20, and 30 mm) on the properties of composites was analyzed. Results showed that the composite made with 10 mm fiber length (C10) showed the utmost tensile strength (58 MPa). Further, the C10 composite was reinforced with Indian Jujube Fruit Seed (IJFS) particles and the effect of particles loading on composite’s behavior was examined. Results indicated that adding up IJFS particles assisted in progress of composite’s properties. Further, the C10/10 wt% IJFS composite showed the better mechanical properties (14% increase in tensile, 23% increase in flexural & impact strengths than C10 composite). Furthermore, the same composite showed least water absorption and bio-degradation characteristics. Hence, it is concluded from this research that the C10/10 wt% IJFS composite is best suited for structural applications as showed improved performance with low weight.
