The potential of using date palm fibres as reinforcement for polymeric composites

A new eco-friendly chemical treatment of natural fibres: Effect of sodium bicarbonate on properties of sisal fibre and its epoxy composites

“…On the other hand, weak adhesion between untreated lignocellulosic fibres and thermosetting resins adversely affects the flexural strength. It is well known that the hydrophilic surface of natural fibres (mainly due to the presence of amorphous cellulose and hemicelluloses) shows poor compatibility with hydrophobic polymer matrices like epoxy resins [27]. This results in weak interfaces that lead to internal strains, porosity, environmental degradation, moisture absorption and poor mechanical strengths of the composites.…”

“…Alsaeed et al [27] used different concentrations (i.e. 3%, 6% and 9%) of NaOH solution to pre-treat date palm fibres for 24 h at room temperature, showing that the increase in NaOH concentration worsens the tensile properties of the natural fibre.…”

Effects of amino silicone oil modification on properties of ramie fiber and ramie fiber/polypropylene composites

“…Therefore, in order to improve the interaction between natural fiber and polymer matrix, it is necessary to decrease the surface hydrophilicity of the natural fiber by surface modification [10,11]. Recently, there are various modification methods for natural fiber that have been reported in the literature, such as sodium hydroxide, maleic anhydride, coupling agent, acetic anhydride, graft copolymers and enzyme modification [12][13][14][15][16]. The main emphasis of these researches has focused on the effect of modifier on properties of composites, but the microscopic mechanism of modification methods at the molecular and atomic scale was rarely studied.…”

Selected biotrends in development of epoxy resins and their composites

“…Some research has also been conducted using banana [83], sugar palm [84], date palm [85,86] and piassava [87] fibres. The main areas of interest regarding natural fibre-reinforced epoxy composites development include the influence of fibre characteristics (type, surface and architecture) and environmental conditions (temperature and medium) on the properties of the composites.…”
