This study investigates the effect of the chemical treatment of sawdust on the mechanical and thermal properties of a clay composite reinforced with sawdust in variable mass proportions: 0.5, 1, 1.5, 2 and 2.5%, intended for use as brick in rural houses in desert areas. The sawdust was chemically treated with 5 wt% NaOH and 0.01 wt% KMnO4 solutions. The mechanical test results of the reinforced composite with alkali-treated sawdust show an increase in flexural and compression strength, reaching a maximum value of 0.89 and 4.85 MPa, respectively. However, the thermal test results show a significant decrease in the thermal conductivity of the sawdust-reinforced composite. The best result recorded is that of untreated sawdust, which has a value of 0.37 (W.m−1.K−1) compared to the one reinforced with treated sawdust.

In this study, the effect of different treatments and the addition of maleic anhydride grafted polyethylene (MAPE) on the mechanical and thermal properties of Alpinia galanga (AG) fiber/high-density polyethylene (HDPE) composites were investigated. The AG fibers were pretreated with sodium hydroxide (NaOH) and then treated with 3-aminopropyltriethoxysilane (3-APE) as well as treated with p-toluenesulfonic acid (PTSA). The samples were first prepared by melt blending method before being injected to specimen dumbbell shape using an injection moulding machine. Three different fiber loadings were studied, such as 3, 6, 10 and 15 wt%. The tensile test results revealed that the NaOH and 3-APE treatments increased the tensile strength of AG/HDPE composites with the addition of MAPE at all fiber loadings, whereas tensile strength of PTSA treatment improved at 3 wt% fiber loading. The morphological studies confirmed a better adhesion between treated fiber and HDPE matrix with the inclusion of MAPE. Thermal analysis study showed that NaOH, 3-APE and PTSA treatments on AG fibers improved the thermal stability of the composites with an addition of MAPE by delaying the thermal degradation of the composites. The water absorption test proved NaOH and 3-APE treated fiber exhibited lower water absorption than other composites with the inclusion of MAPE. Overall, the results indicated that chemical treatment with NaOH and 3-APE with the presence of MAPE is a good approach towards the development of natural fiber composites.
