INTRODUCTION A composite is considered to be a multiphase material that resides in the possibility of combining physical properties of the constituents to obtain new structural or functional properties [1]. The fibres in reinforced composites act as the principle load carrying members while the matrix serves to transmit the load to the fibres and protects it from environment attack and damage due to handling [2]. Natural fibres are increasingly used as an alternative to synthetic fibres as the reinforcement agent in fabrication of polymer composites. This is because natural fibres like bamboo, coir, sugar cane bagasse, coconut, kenaf, hemp are replenishable agricultural resources, economically feasible, biodegradable, and possess attractive physical and mechanical properties [3-6]. Bamboo fibre is a regenerated cellulose fibre, which is produced from bamboo pulp processed from bamboo culms. Apart from having a high strength-to-weight ratio, bamboo fibre is recognized as one of the most attractive reinforcement in polymer composites because the effect of water absorption on its mechanical properties is comparatively lower than other natural fibres [7-9].

Mechanical, morphological, and thermal properties of the raw and delignified wood sawdust (DWS) reinforced unsaturated polyester (UP) composites were evaluated. Composites were prepared using Resin Transfer molding technique by changing filler loading (5, 10, 15, and 20 wt%) for both raw and DWS reinforced UP. Mechanical (tensile and flexural), Fourier transform infrared spectroscopy (FTIR), morphological (scanning electron microscopy [SEM]) and thermal (thermogravimetric analysis [TGA]) properties were successively characterized. FTIR confirmed the removal of lignin from wood sawdust during the delignification process. The tensile strength, Young's modulus, and flexural strength values increased only up to 15% filler loading then decreased with increasing the filler. DWS reinforced composites had better mechanical properties compared to raw composites. SEM micrographs reveal that DWS reinforced composites have good compatibility with UP resin. According to TGA results, DWS reinforced composites showed enhanced thermal stability at the final decomposition stage above 4008C. J. VINYL ADDIT. TECHNOL., 00:000-000, 2016.

“…19 we can analyze a better distribution of the load, compared to Figure 17 in which we have the 5% load composite (MP), because its shows signs of pull-out of the particles in the matrix which (Wong et al, 2010), that the quality of the interface can be determined by the chemical and physical factors that determine the quality of the interface. In turn, are related to surface area, purity of reinforcement, matrix wettability and differences in the thermal and mechanical properties of the constituent materials.…”

The objective of this work was to study the viability of the use of the crushed corn cob, employed as load in a composite polyester resin. The specimens were produced with 5, 10 and 20% by weight of the ground corn cob, as fine particles (FP), medium particles (MP) and large particles (LP) to investigate the influence of the loading content on the mechanical and thermal conductivity properties of the composite material. The results of the mechanical tests, the data of impact test presented a satisfactory result for all the composites. However, the photomicrographs of the composites through SEM indicated low mechanical load/matrix adhesion, with few signs of effective stress transfer between phases, noting that the most viable particle size is the fine particle (FP). The composites shown to be viable for thermal applications, with a thermal conductivity of 0.138 W/m lower than 0.21 W/m, being classified as thermal insulation.Palabras clave: polyester resin, corn cob, modulus of elasticity, thermal conductivity, insulation. ResumenEl objetivo de este trabajo fue estudiar la viabilidad del uso de la mazorca de maíz triturada, empleada como carga en una resina compuesta de poliéster. Los especímenes se produjeron con 5, 10 y 20% en peso de la mazorca de maíz molido, como partículas finas (PF), partículas medianas (PM) y partículas grandes (PG) para investigar la influencia del contenido de carga en la mecánica y térmica propiedades de conductividad del material compuesto. Los resultados de las pruebas mecánicas, en impacto presentaron un resultado satisfactorio para todos los compuestos. Sin embargo, las fotomicrografías de los compuesto por los SEM indicaron una baja adhesión carga/matriz, con pocos signos de transferencia efectiva de tensión de las fases, señalando que el tamaño de partícula más viable es la partícula fina (PF). Los compuesto mostraron ser viables para aplicaciones en aislamiento térmico, con una conductividad térmica de 0.138W/m abajo 0.21W/m.
