Influence Of Water Absorption On The Mechanical Properties Of Jute Fibre Bio-Composite

Bio-composites are increasingly viewed as a renewable alternative to synthetic composites in many applications. However, low durability and rapid degradation of biocomposites in outdoor applications have become a major problem. In particular, wet environments can cause a rapid deterioration in the m...
