CBS decomposes at elevated temperature and yields benzothiazole sulfide radicals, which react with the PP polymeric free radicals generated during the processing of the composites.

(author)īenzothiazole sulfide compatibilized polypropylene/halloysite nanotubes compositesĮnergy Technology Data Exchange (ETDEWEB) Crystallinity was measured by means of X Ray diffraction and fractured surfaces were observed and analyzed by scanning electron microscopy.
Thermal behavior was investigated by heat deflection temperature tests. The mechanical behavior of the composites was studied by carrying out tensile, flexural, impact and fatigue tests. An investigation was carried out with 8 compositions by varying the average fiber size (lower level = 0.94 mm and upper level = 2.19 mm), fiber content (20 and 40 weight %) and compatibilizer PP-g-MA (1 and 4 weight %). Interfacial adhesion between the two materials was achieved by the addition of compatibilizer maleic anhydride grafted polypropylene PPg- MA. An investigation was performed on the mechanical and thermal behavior of a composite comprising a polypropylene thermoplastic matrix and bamboo fibers (Phyllostachys Edulis). Research on composites reinforced with natural cellulosic fibers seeks to meet that need. The contemporary need for ecological preservation is a challenge to the realms of science to develop environmentally sustainable materials and processes. International Nuclear Information System (INIS)Ĭaranti, Lilian R.A. Linear regression model is fitted and follow the assumptions of normal distribution.Įffect of compatibilizer, bamboo fiber size and content on the mechanical properties of PP-g-MA compatibilized polypropylene/bamboo fiber composites The highest yield strength of 27.68 MPa is provided at the ratio of 70/30 blend by using the 0.3 phr of PP-g-MAH and 0.03 phr of DCP. (2) there are interaction between PP-g-MAH and DCP that have affected the final properties of PLA/ PP blend. Because the adding of PP-g-MAH and DCP resulted in improving compatibility between PLA and PP. The results show that (1) the yield strength of PLA/ PP blend are increased after addition of compatibilizer.

Yield strength is characterized to study the interaction between compatibilizer, initiator and yield strength by using experimental design of multilevel full factorial. In addition, (1) polypropylene grafted maleic anhydride ( PP-g-MAH) as a compatibilizer at 0.3 and 0.7 part per hundred of PLA/ PP resin (phr) and (2) dicumyl peroxide (DCP) being an initiator at 0.03 and 0.07 phr are added in each composition. The PLA is blended with PP (PLA/ PP) at the ratios of 70/30, 50/50 and 30/70. The aim of this research is to study the relationship between compatibilizer and yield strength of polylactic acid (PLA) and polypropylene ( PP) blend. Jariyakulsith, Pattanun Puajindanetr, Somchai
