“…Advancing and receding contact angles of various test liquids were measured on the technical flax fibres under controlled conditions (see section 2.2), with a Krüss K100 tensiometer using the Wilhelmy technique [6,13]. The selection of water, diiodomethane, and ethylene glycol as test liquids is based on the difference of surface energy components between them (water is presumed predominantly acidic, ethylene glycol is basic, and diiodomethane is a non-polar liquid), according to the Van Oss model [14] and the scale proposed by Della Volpe [15].…”

The influence of moisture content in the environment during manufacture of a novel cobalt-free UP matrix reinforced with flax fibres, on the fibre-matrix adhesion was studied. Flax surface energy was experimentally determined by measuring contact angles on technical fibres, using the Wilhelmy technique and the acid-base theory. The mechanical strength of the interface under different humidity conditions was characterized by the critical local value of interfacial shear stress, τ d , at the moment of crack initiation, which was assessed by single-fibre pull-out tests. Differential scanning calorimetry and x-ray photoelectron spectroscopy analysis gave further insight into the topic. The results suggest that the effect of humidity during manufacturing on the composite interface might be limited. However, longitudinal composite strength decreased somewhat for composites produced in humid conditions, showing that there is some detrimental effect of high levels of moisture during cure on the fibre mechanical performance, likely caused by some fibre degradation.

“…Water droplets have difficulty spreading on hydrophobic surfaces, and the more rounded water that droplets remain, the larger the contact angle becomes. Because LDPE is a non-polar and hydrophobic material, the water contact angles of the tested BPCs (Table 4) were higher than that of bamboo, which ranges from 50° to 70° (Ahmad and Kamke 2003;Fuentes et al 2011). The water contact angle increased with the increasing BC content.…”

The use of bamboo charcoal (BC) was investigated as a filler in bambooplastic composites (BPCs) to achieve improved water resistance, physical-mechanical properties, and reduced hydrophilicity. The influence of the BC content and size on the water absorption, contact angle, density, and mechanical properties of bamboo flour/low-density polyethylene (LDPE) composites was tested. Scanning electron microscopy was used to analyse fractured and flat composite surfaces. The results indicated that the BC increased water resistance, achieving optimal results at 8% content. The BC particles that ranged in size from 60 to 100 mesh were more water-resistant than other sized BC. The water contact angle increased with an increase in the BC content or a decrease in the particle size. These results indicated that BC reduced the composite hydrophilicity and that the smaller BC particles improved this effect. The BC strongly connected with the LDPE composites, and the BC contents below 12% improved the flexural properties and increased the density of the BPCs. Also, the impact strength of the BPCs decreased dramatically with a decrease in the BC particle size. These results demonstrated that the integration of BC with BPCs resulted in strengthened water resistance and physical-mechanical properties and reduced hydrophilicity.

Bamboo-plastic composites (BPCs) are manufactured via hot pressing and extrusion or injection moulding using thermoplastics and bamboo instead of wood (Yeh et al. 2009;Wu et al. 2013). BPCs are widely used in decorations, outdoors, and as non-structural components of buildings (Xian et al. 2015) because they are biodegradable, renewable, and environmentally friendly materials (Zhou et al. 2015a). However, the interface between the polar, hydrophilic bamboo fibres and the non-polar, hydrophobic low-density polyethylene (LDPE) is weak, which leads to the formation of many gaps and pores between the two materials. This incompatibility results in poor mechanical properties and renders the composites vulnerable to water penetration and fungal attack (Hosseinihashemi et al. 2011;Mbarek et al. 2013). Bamboo fibre processing (Li et al. 2013) and coupling agent addition (Tran et al. 2013) are widely used PEER-REVIEWED ARTICLE bioresources.com Chen et al. (2016).

Another method of eliminating gaps is filler addition, which is a simple and low-cost way to effectively improve the composite morphology and mechanical properties.
