Mechanical Investigation of Hemp Fiber Reinforced Polypropylene with Different Types of MAPP Compatibilizer
Mechanical properties of hemp fiber reinforced polypropylene were investigated. Hemp fibers were carded together with polypropylene fibers, and needle punched. Composites were prepared by hot pressing of the PP/hemp mats. Hemp content was varied between 0 and 50 % by weight, in 10% steps. A treatment with two different maleic anhydride grafted polypropylenes was applied in order to increase the fiber/matrix surface adhesion. Tensile, three-point bending and Charpy tests were carried out on the treated and untreated composites.
