“…The loss of composites in tension upon exposure was ≈ 3%, 5%, 10% and 11% respectively over control samples as it is showed on the histogram below: Figure 8. Residual apparent tensile strength of tested GFRP composites One early effect of this alkaline aqueous environment was the appearance of a milky colour on the surface of composites as reported elsewhere [28].…”

Abstract. The last decades of the XXe century cognized a huge extent of composite materials uses to almost all everyday life's applications, replacing the conventional materials, due to their outstanding properties especially highest strength-to-weight ratio and the ability to be designed to satisfy specific performance requirements. To get the most out of these wonder materials, a new concept, combining polymer concrete and composite laminates, is currently used in Algeria. This research work has the aim to investigate applicability of this concept in civil engineering through tensile and bending tests. On the other hand, the influence of various chemicals (Sodium hydroxide, Potassium Hydroxide and Calcium Carbonates) on our material and its tensile properties retention over long-time exposure was examined. The mechanical properties obtained indicate the convenience of this material for use in civil engineering thanks to its very good tensile and flexural performances in addition to its sufficient residual strength after theoretically 56 years.

Abstract. In this study, 30 wt% aligned untreated long hemp fibre/PLA (AUL) and aligned alkali treated long hemp fibre/PLA (AAL) composites were produced by film stacking and subjected to accelerated ageing environment. Accelerated ageing was carried out with an accelerated ageing chamber using UV-irradiation and water spray at 50 °C for four different time intervals (250, 500, 750 and 1000 hrs). After accelerated ageing, tensile strength (TS), flexural strength, Young's modulus (YM), flexural modulus and mode I fracture toughness (K Ic ) were found to decrease and impact strength (IS) was found to increase for both AUL and AAL composites. AUL composites had greatest overall reduction in mechanical properties than that for AAL composites upon exposure to accelerated ageing environment. FTIR analysis and crystallinity contents of the accelerated aged composites support the results of the deterioration of mechanical properties upon exposure to accelerated ageing environment.

“…The moisture absorbed by the composite produced mainly the swell of the reinforcement but also the plasticization of both the polyester resin and the natural reinforcement, as it was reported for similar systems. 28 However, because the adhesion between the acetonewashed jute and the polyester resin was better than in the other composites, the empty space between the fiber and the matrix was limited, and the fiber could not swell very much; thus, the decrease in impact energy due to the absorbed moisture was the lowest. In the case of the untreated and detergent-washed composites, the fibers could swell more than the acetone-washed ones; the empty space between the reinforcement and the resin disappeared, and the fibers exerted pressure on the matrix.…”

As-received and washed jute fabrics were used as reinforcement for a thermoset resin. The mild treatments performed on the jute fabrics did not significantly affect their physical and thermal behaviors. The washed fibers absorbed less water than the unmodified (as received) ones, indicating that the coating used to form the fabrics was hygroscopic. Measurements of the fiber mechanical properties showed a high dispersion due to fiber irregularities, although the values obtained were in agreement with data reported in the literature. These results were also analyzed with the Weibull method. To investigate the effect of the jute treatments on the interface properties, impact, compression, and tensile tests were carried out. The composites made from as-received jute had the highest impact energy, which was probably associated with weak interfacial adhesion. Composite samples behaved more ductilely in compression than in tensile situations due to the brittle characteristics of the resin used as matrix. The effect of the orientation of the fibers with respect to the direction of the applied force in the different mechanical tests was also studied. © 2005 Wiley Periodicals, Inc.
