Impact and Tensile Properties of Alkaline Treated Textile Fibre Reinforced Polymer Composites

Alkaline treatment's effect plays a vital role in determining textile fibre reinforced polymer materials' mechanical properties. This study's primary concern was to obtain the optimum concentration of alkali solution affected by textile fibre reinforced polymer composite's mechanical properties under impact and tension loading. The textile fibre was treated with an alkali solution known as sodium hydroxide (NaOH) with distinct weight percentages (1, 3, and 5wt%). The low-velocity impact test (ASTM D7136) and tensile test (ASTM D3039) were conducted to analyse the tensile and impact properties of untreated and treated composite specimens. All specimens prepared in this research were the end products of the compression moulding process. The tensile strength and impact resistance result improved when textile fibres were treated with 1wt% NaOH solution based on the tensile and impact test results.
