“…The characteristic times t d , t L , and t e obtained with fibre-reinforced composite materials increased compared to the UPR results, in particular, when the fibres were chemically treated (see Figure 4b). These significant decreases in water diffusivity consisted of an additional factor to the reduction of P, together with the water solubility S. Similar tendencies, in terms of water diffusivity and permeability, were obtained with UPR/flax fibre-based composites before and after plasma treatment [23].…”

AbstractSilane (Si) and styrene (S) treatments were applied on flax fibres in order to improve their adhesion with a polyester resin and to increase their moisture resistance. The water sorption and permeation kinetics of the composites were correlated with the water sorption behaviour of untreated and treated fibres. An increase of the water barrier effect was observed in treated fibres-based composites in comparison with untreated ones. This was related to the shift-down of water solubility and to a decrease of the water diffusivity in treated fibre-based composites. In the case of (S) treatment, the presence of styrene increased the moisture resistance of the treated fibres and made compatible the fibres and the matrix. In the case of (Si) treatment, a good hydric fibre/matrix interface was obtained due to crosslinking reactions and hydrogen bonding between water molecules and free hydroxyl groups of (Si) treated fibres. In order to interpret water permeation behaviour of composite films, a simple illustrated model is suggested and represented by a schematic view.

“…With a strong interface between fiber and matrix, higher mechanical property is assured. 12,13 The compatibility of reinforced TLCP and matrix plays an important part in the interfacial adhesion. Considering the compatibility of TLCP and unsaturated polyester (UP), one kind of reactive TLCP with terminal double bond group was synthesized in our laboratory.…”

To improve the performance of unsaturated polyester (UP) under cold-heat alternate temperature, selfsynthesized reactive thermotropic liquid crystalline polymer (TLCP)-methacryloyl copolymer (LCMC), UP, and glass fiber (GF) hybrid composites was prepared by molding technology. The apparent activation energy and crystal behavior analysis of LCMC/UP blends were investigated by Differential scanning calorimetry and X-ray diffraction (XRD), respectively, the results showed that the addition of LCMC can reduce apparent activation energy and accelerate the curing reaction of UP, the XRD analysis indicated that the crystal phase of LCMC still exist in the blends after blending with UP. The effect of LCMC content on the properties of LCMC/UP/GF hybrid composites such as impact strength, bending strength, and ring-on-block wear were also investigated through static mechanical tests and wear tests. The mechanical properties of hybrid composites increased significantly because of the addition of LCMC. The wear tests showed that LCMC can improve the wear resistance of the UP/GF/LCMC hybrid composites even though the content of LCMC was at a relatively low level (5-7.5 wt %). This makes it possible to develop novel kind of UP-based materials with good wear resistance for various applications. The Worn surface was observed by scanning electron microscopy (SEM) and the mechanism for the improvement is discussed in this paper.
