Chemically Treated Pinus Roxburghii Fibre Reinforced PLA Composites: An Overview

Numerous investigations have been undertaken to discover which natural fibre composites are best suited for certain technical uses. Natural fibres are preferable due to their many positive qualities, including their low density, cheap cost, simplicity of use, durability, and biodegradability. The Pinus roxburghii needles (PRN) are abundant in the Indian state of Uttarakhand's mountainous northern area. Using PRN fibre in bio-composite reinforcement may lessen the need for synthetic fibre and put more of a focus on the use of natural resources. Considering this, this chapter discusses how Pinus roxburghii fibres (PRF) may be used to strengthen polylactic acid (PLA) composites while also being renewable. Study topics include PRF extraction, alkali treatment, and subsequent usage in the creation of PLA-based composites.
