Currently, there is a lack of comprehensive scientific knowledge on the response hygrothermal ageing rice stubble-based composites, which limits their potential applications. In this work, effect alkali and water pre-treatment ageing, mechanical strength, contact angle, morphology stubble fibre-reinforced polymer composites presented. The stubble-reinforced are fabricated using two different weight fractions (50% 60%) inside matrix resin. Accelerated environmental performed temperature-controlled bath moisture-controlled humidity chambers for 7 14 days. results environmentally aged specimens compared with untreated virgin specimens. tensile strength improved by ∼177% (65%), (alkali) pre-treatment. There notable improvement in flexural modulus as well. mass gain analysis conducted submerged environments. reduced ∼20% angle ∼18%, comparison to composites. Although both pre-treatments resulted significant hygro-mechanical properties wettability characteristics appears be more promising alkali-treatment. findings have implications spurring development straw-based through proposed pre-treatments. usage waste low medium load-bearing applications, such furniture, partition boards, packaging materials can help curb burning practice save environment.
