Abstract– Fully biodegradable natural fiber/biodegradable polymer composites have drawn a most of interest from researchers and have a number of uses, including components for but their use is restricted by their flammability. It's important to use environmentally sound flame retardants to increase the flame resistance of completely degradable composites. The physical properties under investigation of The great toughness, bulkiness, low heat conductivity, ability to insulate sound and heat, antistatic qualities, and other characteristics of coconut shell powder make it unique. Due to these properties, coconut shell powder is most appropriate for application in the production of composite materials under specific conditions. The flame-retardant properties of powdered coconut shell were investigated. For the purpose of making the experimental panels, ammonium polyphosphate, which was mixed with coconut shell powder, was reviewed as a flame retardant chemical. For the purpose of making the experimental panels, four fire retardant focusses (0, 1, 2, and 3%) and 20% coconut shell powder were mixed with resin.  Both impact and tensile testing were carried out mechanically. Ammonium polyphosphate was shown to reduce PLA's tensile and impact strengths while increasing the amount of flame retardant. The fire retardant was improved maximum than with less concentrations of ammonium polyphosphate.
