Abstract

The main purpose of doing this project is to study the effects of maleatcd polypropylene (MAPP) addition to the properties of rubber seed shell powder (RSSP)/ Polypropylene (PP) composites fabrication by using mechanical testing methods. For sample preparation, firstly the rubber seed shell is separated from its seed then c leaned by water. After being dried, this rubber seed shell is pulverized by rotor mill s. This pulverization process is carried out to transform the shell into the powder form. This process is conducted at Material Laboratory, UTeM. Four different compositions of MAPP concentration are used which arc 0 wt %, 3 wt %1 7 wt% and 9 wt %. A mould with dimension 400 mm x 400 mm x 3 mm is used to fabricate the composite. The sample fabrication is done through mixing, ex trusion ~ crushing and hot pressing process. After that, the testings are done in order to assess the mechanical properties of composites. The test methods used are tensile test, llex'Ural and impact test. From these testing, it can be concluded that the strength Qf composite is increased when the MAPP is added, the optimum weight percentage of MAPP is 3 wt% for better mechanical properties.
