Abstract
A composite board is manufactured from hydrophobic coconut coir fibers which have been treated to remove at least a portion of coconut pith therefrom; and a hydrophobic vinyl polymer, such as a polyolefin. The composite board is manufactured without any step of chemically modifying coconut coir fibers. The composite board is manufactured by removing at least a portion of coconut pith from coconut coir fibers using a cyclonic separator; combining coconut coir fibers with a hydrophobic polymer to form a mixture; and extruding the mixture to form a composite board.
