“…This improved fire retardancy was attributed to the thermal shielding and diffusion barrier effects yielded by the effective silica layer formed during the combustion process together with the addition of flame retardant agents that slow the propagation of the burning reaction. The high silica content in rice husks may also contribute synergistically [51]. At higher loading of flame retardant, the mechanical properties of the composites tend to decrease.…”

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

et al. 2013

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. Dear EditorI would like to submit a paper entitle of "Degradability of Polymeric Composites Based on Natural Fibres" to the materials and design. This paper address important issues related to the degradation of natural fibres in polymeric composites. I believe the paper has interest to the reader of the journal and will be beneficial for many researchers in the field of materials and design considering the degradation of polymer and bio-materials. I would like to confirm that the paper has not been sent to any journal before and not under review. I hope you can send the paper fore reviewing process.

Hemp fibers and particles, with different sizes and contents, were used to make hybrid composites based on recycled polypropylene (PP). In particular, the effect of maleated polypropylene (MAPP) addition on the morphology and mechanical properties is reported. The results show that better adhesion is obtained with MAPP addition. In general, fiber content and size had a substantial effect on the tensile, flexural, torsion, and impact properties of the resulting composites. Although, adding MAPP to the samples improved the impact strength of the composites, the values were always lower than neat PP.

Natural fiber reinforced polylactic acid composites: A review

et al. 2018

View full text Add to dashboard Cite

Biopolymer‐based composites have attracted the attention of researchers and industries due to their eco‐friendliness and environmental sustainability, as well as their suitability for a number of applications. Biocomposites containing natural fibers and biopolymers would be the ideal choice in the development of biodegradable materials for different applications. Polylactic acid (PLA) is an environmentally interesting biopolymer, which also has exclusive qualities, such as good transparency and processability, glossy appearance, and high rigidity, although it has some shortcomings as well, for example, its brittleness and high rate of crystallization. PLA‐based natural fiber composites are entirely bio‐based materials with promising biodegradability and mechanical properties. Several research studies have been carried out on PLA and its composites to explore their potential to substitute petroleum‐based products, but until now there is no comprehensive review with up‐to‐date research data available in the literature. The aim of this review is to highlight the trends in the research and development of PLA and PLA‐based natural fiber composites over the past few years. This review article covers current research efforts on the synthesis and biodegradation of PLA, its properties, trends, challenges and prospects in the field of PLA and its composites. PLA‐based composites are moderately abundant; and further research and development is needed for cost reduction and broader utilization. POLYM.
