“…For instance, sisal fibre/cement composites showed that drying shrinkage increases with presence of sisal fibres as reported in [12]. The drying shrinkage of cement matrix is related to the magnitude of its porosity and to the size, shape, and continuity of the capillary system in the hydrated cement paste, i.e.…”

“…Many efforts are currently being undertaken to expand its application, for instance, the development of continuous sisal fibre reinforced composites that allows the design of thin walled elements with high strength in tension and compression. Its applications may include permanent formworks, facades, tanks, pipes, long span roofing elements, strengthening of existing structures, and structural building members [12]. The application of natural fibres is also being studied in geotechnical engineering.…”

A review on the degradability of polymeric composites based on natural fibres

The applications of natural fibre/polymer composites in civil engineering are mostly concentrated on non-load bearing indoor components due to its vulnerability to environmental attack. This paper evaluates the characteristics of several natural fibre composites exposed to moisture, thermal, fire, and ultraviolet degradation through an extensive literature review. The effects of chemical additives such as fibre treatments, fire retardants and UV stabilizers are also addressed. Based on the evaluation conducted, optimum fibre content provides strength in a polymer composite but it also becomes an entry point for moisture attack. Several fibre treatments are also being used to improve fibre/matrix interface, thereby increasing moisture durability. However, the treated fibres were found to behave poorly when exposed to weather. The addition of UV stabilizers and fire retardants are suggested to enhance outdoor and fire performance of natural fibre/polymer composite but compromises its strength. Therefore, from the collected data and various experimental results, it was concluded that an optimum blend ratio of chemical additives must be employed to achieve a balance between strength and durability requirements for natural fibre composites.

“…Generally, fibres' ability to resist crack deflection, debonding, and to bridge cracks, slows down crack propagation in fibre reinforced composites and increases the fracture energy [39][40][41][42]. Figure 8 shows the influence of FF content on the fracture toughness of geopolymer composites.…”

Characterisation of mechanical and thermal properties in flax fabric reinforced geopolymer composites

This paper presents the mechanical and thermal properties of flax fabric reinforced fly ash based geopolymer composites. Geopolymer composites reinforced with 2.4, 3.0 and 4.1 wt% woven flax fabric in various layers were fabricated using a hand lay-up technique and tested for mechanical properties such as flexural strength, flexural modulus, compressive strength, hardness, and fracture toughness. All mechanical properties were improved by increasing the flax fibre contents, and showed superior mechanical properties over a pure geopolymer matrix. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) studies were carried out to evaluate the composition and fracture surfaces of geopolymer and geopolymer/flax composites. The thermal behaviour of composites was studied by thermogravimetric analysis (TGA) and the results showed significant degradation of flax fibres at 300 ℃.

“…The use of cellulosic fibers as reinforcements for cement composites represents an interesting option for the building industry (Tonoli et al 2009(Tonoli et al , 2010Silva et al 2010;Claramunt et al 2011). These fibers provide adequate stiffness, strength, and bonding capacity to cement-based matrices for the substantial enhancement of their flexural strength, toughness, and impact resistance.…”

A combination of reinforcements at different levels can have a synergetic effect on the final properties of a composite. The aim of this work was to produce, evaluate, and compare the wet/dry cycling durability of the exposure of cement composites reinforced with conventional pulps at the micro-scale level, with nanofibrillated cellulose fibers at the nano-scale level, and with combinations of both reinforcements (hybrid composites). To evaluate the durability of their mechanical properties, the composites were tested under flexural loading after 28 days of humidity chamber curing and after 20 wet/dry accelerating aging cycles. Composites reinforced with the nanofibrillated cellulose exhibited significantly higher flexural strength and flexural modulus, but they had lower fracture energy values than those reinforced with conventional sisal fibers. Moreover, the hybrid composites with a high content of nanofibrillated cellulose maintained or even improved their properties after aging.
