    Improving the properties of natural fibers can be interesting from a technological point of view. Modifications can result in a high specific strength, electromagnetic interference (EMI) shielding, antistatic brush etc. Plant fiber composites would make them an option for use in components such as rifle stocks and knife handles etc. The greatest challenge would be to ensure that the components are all weather capable, but today several materials exist that have a high moisture tolerance. Moreover with proper surface coating techniques, most natural fibers materials can be toughened up to use as reinforcement. An attempt was made using a proprietary experimental set-up to coat natural fiber with electroless nickel phosphorus (ENi-P), since sisal fiber is a non-conducting material. In this article the surface morphology, ingredients and cross-section images of the modified natural fibers were characterised by a scanning electron microscope equipped with EDAX.Poprawa w艂a艣ciwo艣ci w艂贸kien naturalnych jest interesuj膮ca z technologicznego punktu widzenia. Wynikiem modyfikacji mo偶e by膰 wysoka wytrzyma艂o艣膰, poprawa ekranowania p贸l elektromagnetycznych (EMI), poprawa w艂a艣ciwo艣ci antystatycznych itp. Pow艂oki niklowo-fosforowe na w艂贸knach ro艣linnych umo偶liwiaj膮 wytworzenie r贸偶nego rodzaju kompozyt贸w, min. o powierzchni odpornej na wilgo膰. Morfologia powierzchni kompozyt贸w by艂a badana za pomoc膮 SEM-EDAX
