Abstract

Aim of study: In this study, it was aimed to establish and optimize a production process for engineering thermoplastic composites based on heat treated wood fillers and SMA copolymer. Material and Methods: As wood material, pine wood (Pinus strobus L.), and as a thermoplastic copolymer material, Styrene Maleic Anhydride (SMA) copolymer were used in this study. Heat treatment was conducted at 212°C for 8 h in an attempt to improve the durability of the wood furnish and the wood flour and SMA compounds were extruded and granulated using a lab-scale grinder. Physical test, mechanical test and morphological tests were calculated. Main results: The results showed that the highest tensile strength was in the 30 wt.% wood flour/SMA and it has been seen that the positive effect on FMOE,TMOE of heat treated wood flour/SMA. Weak interfacial bonding was observed between the polymer and wood filler from the SEM images of the fractured surfaces of wood flour/SMA composites. Research highlights: The results from this research indicated the compatibility of the SMA copolymer with the wood flour and the changes in the mechanical strength of the material. Due to limited heat treated wood thermoplastic composite usage in the field of wood engineering, there is a need for more extensive work in the future.

Finite Element Analysis of Heat Treated Wood Filled Styrene Maleic Anhydride (SMA) Copolymer Composites

“…Since the contribution of deformation to numerical solutions is very little, the weight of the material has been neglected. Some mechanical values entered into the program for numerical analysis of the model are given in Table 2. lished in the literature (Ayrılmış et al, 2011;Aydemir et al, 2015c;Zor et al, 2018). To the best of authors' knowledge, there is no information related to simulation analysis of heat treated lignocellulosic-fi lled SMA thermoplastic composites.…”

Bagasse fiber reinforced chemically functionalized polystyrene composites

“…Although this study selects a CF-PS as a matrix, that is a polystyrene functionalised with MA, however, it has been noted that styrene maleic anhydride (SMA) and foamed SMA (F-SMA) have been used as matrix for composites. SMA matrix composites have been processed by using the following particulate reinforcements: Natural 44 and heat treated [45][46][47][48] wood flour, natural [49][50][51] and heat treated [52][53][54] pine wood flour, potato starch, 55 alpha cellulose (AC), 55 ultra-fine cellulose (UFC) 55 and glycerine treated nanofibrillated cellulose (GNFC). 56 F-SMA matrix composites have been processed by using the following particulate reinforcements: Wood flour, [57][58][59][60] potato starch [58][59][60] and microcrystalline cellulose (MCC), AC and nano fibrillated cellulose (NFC).…”

Surface characterization of weathered and heat‐treated wood‐based composites reinforced by styrene maleic anhydride

“…[15][16][17] The maleic anhydride functionality improves the properties of the copolymer compared with polystyrene, especially the heat resistance. 18 In previous studies, we investigated the possibility using foamed SMA copolymer composites in wood applications, 19 the effect of mechanical properties on heat-treated wood flour/SMA copolymer composites, 20 and the effect of thermal treatment on the surface properties of heat-treated wood flour/SMA composites. 21 In a subsequent study, we reported on furniture performance test of wood-filled SMA composites.…”
