Bamboo fiber-reinforced polypropylene composites: A study of the mechanical properties

Abstract

ABSTRACT:A new type of bamboo fiber-reinforced polypropylene (PP) composite was prepared and its mechanical properties were tested. To enhance the adhesion between the bamboo fiber and the polypropylene matrix, maleic anhydride-grafted polypropylene (MAPP) was prepared and used as a compatibilizer for the composite. The maleic anhydride content of the MAPP was 0.5 wt %. It was found that with 24 wt % of such MAPP being used in the composite formulation, the mechanical properties of the composite such as the tensile modulus, the tensile strength, and the impact strength all increased significantly. The new composite has a tensile strength of 32-36 MPa and a tensile modulus of 5-6 GPa. Compared to the commercially available wood pulp board, the new material is lighter, water-resistant, cheaper, and more importantly has a tensile strength that is more than three times higher than that of the commercial product.

Giant Bamboo Fiber Reinforced Epoxy Composite in Multilayered Ballistic Armor

“…Owing to its relatively low density, 1.03 -1.21 g/cm 3 , and convenient tensile strength, 106-204 MPa [12] the bamboo culm and extracted fiber have been, since long time , used in engineering applications. As an abundant natural resource in tropical and temperate regions, especially Asia and Latin America, bamboo is substituting plastics in civil construction, furniture and lightweight parts of vehicles 33,34 . However, the cylindrical shaped culm limits some direct uses of the bamboo and motivated investigations on bamboo fiber as reinforcement of polymer composites [33][34][35][36][37][38][39][40][41][42][43][44] .…”

Actually, a bamboo fiber corresponds to many microfibrils (sclerenchyma cells) and vessels, known as vascular bundle, which may be extracted from the parenchyma cell matrix by longitudinal slicing procedure 45 .…”

The Effects of Rattan Filler Loadings on Properties of Rattan Powder-Filled Polypropylene Composites

“…For example, sawdust has been utilized in producing composites as substitute for timber (Tajvidi and Ebrahimi 2003;Chen et al 1998). Non-wood forest produce, such as rattan, holds a high value due to its importance and wide usage in the local economy.…”

“…Meanwhile agro-wastes and agro-forest materials, which are abundantly present in developing countries, are also constantly being researched to provide an alternative to synthetic fibres and reinforcements (Thwe and Liao 2000). Non-wood forest produce, such as bamboo, have gained much attention as reinforcement (Chen et al 1998;Wang et al 2008). A few researchers have examined the utilization of rattan powder as filler in rubber composite, where according to the studies, the use of different filler loadings has resulted in deterioration of the tensile properties and fatigue life of the composite Muniandy et al 2012).…”

Bamboo Particles-Polyvinyl Chloride Composites: Analysis of Particles Size Distribution and Composites Performance

“…Chen, Guo, and Mi (1998) reported the values of tensile strength of bamboo fibre-PP composites (at 20% -60% bamboo loading) were less than 20 MPa, tensile modulus values were less than 4000 MPa, whereas Mohanty and Nayak (2010) revealed the value of bending modulus and bending strength of untreated bamboo-high density PE composites (at 40% bamboo loading) were 2987.70 MPa and 25.35 MPa, respectively. Figure 8, the use of fine bamboo particles (75-µm) in the formulation was capable in influencing the increases of impact strength of the composites.…”
