Mechanical, dynamic mechanical and morphological properties of composites based on recycled polystyrene filled with wood flour wastes

Abstract

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.

Complex modification effect of linseed cake as an agricultural waste filler used in high density polyethylene composites

“…It cannot be excluded that the decrease of linseed oil viscosity related to the temperature increase [42] resulted in more intensive migration of the oil from the filler. It provided suppression of the potential reinforcing effects induced by incorporation of rigid lignocellulosic structures, which was observed as an increase in G′ [43,44].…”

Effect of silicon dots into coconut fibers on the nucleating capacity of β-crystals of polypropylene

“…In this study, the effect of alkaline treatment is appreciated because the composite with the untreated fibers has greater values than the composites with the treated fibers; this would demonstrate that a composite with poor interfacial adhesion between the filler and the matrix will tend to dissipate more energy, showing a higher tan δ peak compared to materials with higher interfacial adhesion (Poletto, 2017).…”

Use of waste plastics for the preparation of adhesives for wood bonding

“…Tovrstni kompoziti se uporabljajo v avtomobilski industriji, gradbeništvu in drugih izdelkih široke potrošnje. Za zagotavljanje ustreznih mehanskih lastnosti kompozita je potrebno dodajati dodatke za izboljšanje adhezije med polimerom in lesnimi delci (Poletto, 2017).…”
