Tensile Properties and Micromorphologies of Sawdust and Chipwood Filled Epoxy Composites

Abstract

In this study, waste wood product obtained from the timber industry originating from various type of wood has been investigated. Research work carried out on the three different sizes of fiber derived from the sawdust (SW) and chip wood (CW). The SW and CW fiber and epoxy resin were blended together respectively using hand tools machine, all specimens of fiber composite were prepared accordance to the ASTM standards. Tensile and morphological properties provide an excellent measure of the degree of reinforcement provided by the fiber to the composite. The tensile modulus increased with the filler size from coast to rough of composites both SW and CW but decreases steadily with the wood–fiber size from rough to soft content. Statistical analysis using one way and two ways analysis of variances (ANOVA) showed that the differences of results obtained from those SW and CW fiber composite samples are significant, which confirm a very firm mechanical performance of the composites through tensile tests. This shows the producing a good quality of SW and CW fibres composite which maybe used for home furniture utilities.

Comparative Study of Inorganic TiO2 Nanoparticles and Organic Sawdust Dispersed Epoxy Based Composites

“…That ultimately decreases the strain ability of epoxy making the composites less flexible [13]. Besides, the increment rate of Young's modulus of Epoxy/TiO 2 is higher than that of Epoxy/sawdust mainly due to their nano size and high surface area.…”

Elaboration, thermogravimetric analysis, and fire testing of a new type of wood‐sawdust composite materials based on epoxy–amine polymers modified with copper(II) hexafluorosilicate

“…One of the promising areas of application of epoxy resins is the development of composite materials based on wood‐sawdust (WS), 2,3 in particular chipboard, oriented strand boards, fiberboards, etc., which are nonetheless highly fire hazardous materials 4 . Unlike binders such as urea–formaldehyde and phenol–formaldehyde resins, the use of epoxy resins to bond WS composite materials is not accompanied by the release of toxic substances (phenol, formaldehyde, solvents) both in the synthesis process and the manufacture and operation of finished products 5,6 .…”

Materiais compósitos particulados em matriz epóxi reforçados com serragem, cimento e silicato de magnésio

“…Foi observado que compósitos feitos de polipropileno de alta densidade promoveram propriedades mecânicas superiores (modulo de elasticidade na flexão de 2 GPa e resistência à flexão de 670 MPa) se comparados com compósitos feitos de polipropileno. Hisham et al (2011) desenvolveram materiais compósitos em resina epóxi reforçados por resíduos de produtos de madeira obtidos da indústria madeireira originários de vários tipos de madeira em três tamanhos diferentes, sendo caracterizados na tração. A análise de variância acusou ser significativo o tamanho das fibras no módulo de elasticidade e resistência à tração, apresentando os maiores valores os compostos fabricados com as fibras de maior comprimento.…”
