Due to environmental reasons and their acceptable mechanical properties, natural fiber based polymer composites have been increasingly used in various applications, e.g. housing materials, automotive parts. However, their low thermal resistance and fire behavior limit the use of these materials. In this work, magnesium hydroxide (Mg(OH)2), as a flame retardant, was incorporated into sisal/polypropylene composites. Ratio of sisal fiber to Mg(OH)2 in each composite sample was varied. Maleic anhydride grafted polypropylene (MAPP) was also used to improve the interface of polypropylene and fillers. Flammability and thermal behavior of the composites were examined using a horizontal burning test and thermo gravimetric analyzer, respectively. Morphology and mechanical properties of the composites were also investigated.

The Impact

In order to enhance the interfacial interactions between the sisal fiber (SF) and the polypropylene (PP) matrix, a water-solubility hyperdispersant which has amphipathic structure and flexible segment was used. Experimental results revealed that when the content of hyperdispersant is 5 percent, the impact strength of the composites was 27.4 kJ·m-2 and the flexural strength of SF/PP composites was 40.1 MPa, which was 64 and 34 wt% higher than that of unmodified systems, respectively. Meanwhile, the crystallinity of the composites also leads to an increase.

Thermal Stability Of

Composites based on polypropylene (PP) and sisal fiber (SF) were prepared by melt blending. Sisal fiber content was 30 phr. Organoclay (OMMT; Cloisite®30B) (1-7 phr) was incorporated into the composites. In addition, maleic anhydride grafted polypropylene (MAPP) was used as a compatibilizer to enhance the interfacial adhesion between PP matrix and sisal fiber and also to improve the dispersion of the organoclay in PP matrix. The addition of OMMT had insignificantly affected mechanical properties of SF/PP composites. However, flame retardancy and thermal stability of SF/PP composites were improved dramatically with the presence of OMMT.

Ammonium polyphosphate (APP) and zinc borate (Zb), as flame retardants were incorporated into sisal fiber/polypropylene (PP) composites. Ratios of APP to Zb were varied. Maleic anhydride grafted polypropylene (MAPP) was used to improve the interfacial adhesion between polypropylene and fillers. Flammability of the composites was examined using a horizontal burning test, a vertical burning test, and a limiting oxygen index test. Morphology and mechanical properties of the composites were also investigated. The composite containing 30 phr of APP and 10 phr of Zb exhibited better flame retardancy than the composites containing other ratios of APP to Zb. The combination of APP and Zb insignificantly changed mechanical properties of the composites. In addition, SEM micrographs of the composites revealed good distribution of flame retardants and sisal fiber in PP matrix.

Green biodegradable plastics have come into focus as an alternative to restricted plastic products. In this paper, continuous long sisal fiber (SF)/polylactic acid (PLA) premixes were prepared by an extrusion-rolling blending process, and then unidirectional continuous long sisal fiber-reinforced PLA composites (LSFCs) were prepared by compression molding to explore the effect of long fiber on the mechanical properties of sisal fiber-reinforced composites. As a comparison, random short sisal fiber-reinforced PLA composites (SSFCs) were prepared by open milling and molding. The experimental results show that continuous long sisal fiber/PLA premixes could be successfully obtained from this pre-blending process. It was found that the presence of long sisal fibers could greatly improve the tensile strength of LSFC material along the fiber extension direction and slightly increase its tensile elongation. Continuous long fibers in LSFCs could greatly participate in supporting the load applied to the composite material. However, when comparing the mechanical properties of the two composite materials, the poor compatibility between the fiber and the matrix made fiber’s reinforcement effect not well reflected in SSFCs. Similarly, the flexural performance and impact performance of LSFCs had been improved considerably versus SSFCs.
