“…Considering practical applications, composite mechanical properties are of major importance (Nachtigall et al 2007, Punyamurthy et al 2014. The tensile strength is one the most important mechanical properties that helps to selected a composite material for several applications (Punyamurthy et al 2014).…”

“…The tensile strength is one the most important mechanical properties that helps to selected a composite material for several applications (Punyamurthy et al 2014). As presented in Table 1, the tensile strength of composites without coupling agent decreased when compared to polymer matrix, due to the weak interfacial adhesion caused by the low compatibility between hydrophilic wood flour and hydrophobic polystyrene.…”

“…In addition, the smaller wood flour particles used, with particle size between 53 and 105 μm, provide a higher specific surface area, causing better stress transfer from the matrix to the wood flour increasing the mechanical properties. The composite modulus is often a property of particular interest (Punyamurthy et al 2014, AlMaadeed et al 2014b. The improvement in composite modulus is an expected outcome because the reinforcement effect caused by the wood flour addition (Eshraghi et al 2016).…”

In this work, the potential for usage recycled polystyrene and wood flour wastes as materials for development wood plastic composites was evaluated. The effects of wood flour loading and coupling agent addition on the mechanical, dynamic mechanical and morphological properties of polystyrene wood flour composites were examined. The results showed that the mechanical properties decreased with the wood flour loading. However, an improvement in composite compatibility was observed when the coupling agent was used resulting in the increase of mechanical and dynamic mechanical properties. A morphological study demonstrates the positive effect in the interfacial adhesion between filler and matrix caused by the coupling agent addition. Based on the findings of this work, both waste materials can be used for development composites with higher performance.

“…In addition, alkali treatment induces rougher surfaces for better adhesion between the fiber and matrix. Prior studies have also shown that alkali treatment of these fibers have improved the performance of reinforced composites in terms of thermal stability [29], water absorption and tensile strength [30,31]. …”

Chemical Treatment of Waste Abaca for Natural Fiber-Reinforced Geopolymer Composite

The use of natural fibers in reinforced composites to produce eco-friendly materials is gaining more attention due to their attractive features such as low cost, low density and good mechanical properties, among others. This work thus investigates the potential of waste abaca (Manila hemp) fiber as reinforcing agent in an inorganic aluminosilicate material known as geopolymer. In this study, the waste fibers were subjected to different chemical treatments to modify the surface characteristics and to improve the adhesion with the fly ash-based geopolymer matrix. Definitive screening design of experiment was used to investigate the effect of successive chemical treatment of the fiber on its tensile strength considering the following factors: (1) NaOH pretreatment; (2) soaking time in aluminum salt solution; and (3) final pH of the slurry. The results show that the abaca fiber without alkali pretreatment, soaked for 12 h in Al2(SO4)3 solution and adjusted to pH 6 exhibited the highest tensile strength among the treated fibers. Test results confirmed that the chemical treatment removes the lignin, pectin and hemicellulose, as well as makes the surface rougher with the deposition of aluminum compounds. This improves the interfacial bonding between geopolymer matrix and the abaca fiber, while the geopolymer protects the treated fiber from thermal degradation.

“…The results showed that the tensile strength of the composites increased with increase in fiber content up to 40% and beyond 40% it showed a decrease in tensile strength. The results indicated that chemically treated abaca fibers can be used as promising materials as reinforcement in the preparation of bio composites [95]. Abaca/PP [96], abaca/PLA [97], and abaca/epoxy composite [98] are some other known composites of abaca.…”

Recognizing the facts of high cost, depleting natural feedstocks of energy and materials along with resulting effects by their production and use on environmental emission of green house gases into environment, potential efforts have been made on the use of low-cost, abundant availability, eco-friendly, and energysaving plant fibers-based biocomposites (PBB) and process. Properties of plant fiber-based biocomposites largely influenced by a number of variables, like fiber types, modification of fibers, processing techniques, and environmental condition. This chapter summarized the ancient to recent research on development of plant fibers-based green and sustainable composite materials types along with processing techniques and properties. Plant fibers-based biocomposites have been usefully used in the field of automobile, construction, packaging, medical, and other.
