“…Natural fiber composites are used on structures such as door panels, seat backs, dashboard, pillar cover, engine insulation, headliner panel, and parcel shelves [5][6][7][8]. Natural fiber composites also have potential applications in construction industry [9], sport equipment [10], and other consumer products.…”

Natural fibers and their composites differ in several aspects with carbon fibers, including higher scatter in strength and different tensile responses. The tensile and bending properties of flax fiber composites were experimentally studied and numerically simulated. Composite panels were fabricated from unidirectional flax fiber tapes and polypropylene films via hot pressing technique. The variation in the properties of flax/polypropylene composites was found to be relatively moderate as compared with that of single natural fibers. A multi-scale finite element analysis (FEA) strategy for the progressive damage prediction of natural fiber composites was developed. The FEA model started from microscale analysis which predicted the effective properties of unidirectional flax ply through representative volume element. Macro-scale analysis was conducted subsequently to predict the properties of composite coupons using the results of micro-scale analysis as inputs. The developed multi-scale FE model successfully predicted the tensile strength, bending behavior, and major failure modes of flax/polypropylene composites.

“…Some of these advantages include good mechanical properties [11][12][13][14], good damping properties [12,13], lightweight [13,15,16], low cost [14,16], biodegradable, and environmental-friendly [13,14,17]. From literature, it is prominent that earlier studies focused on the viability of natural fibres but not on the understanding of their acoustical properties.…”

Soldiers and supporting engineers are frequently exposed to high low-frequency (<500 Hz) cabin noise in military vehicles. Despite the use of commercial hearing protection devices, the risk of auditory damage is still imminent because the devices may not be optimally customised for such applications. This study considers flax fibre-reinforced polypropylene (Flax-PP) as an alternative to the material selection for the ear cups of commercial earmuffs, which are typically made of acrylonitrile butadiene styrene (ABS). Different weaving configurations (woven and nonwoven) and various noise environments (pink noise, cabin booming noise, and firing noise) were considered to investigate the feasibility of the proposed composite earmuffs for low-frequency noise reduction. The remaining assembly components of the earmuff were kept consistent with those of a commercial earmuff, which served as a benchmark for results comparison. In contrast to the commercial earmuff, the composite earmuffs were shown to be better in mitigating low-frequency noise by up to 16.6 dB, while compromising midfrequency acoustical performance. Consequently, the proposed composite earmuffs may be an alternative for low-frequency noise reduction in vehicle cabins, at airports, and at construction sites involving heavy machineries.

“…Composite materials have become very interesting with their use in the aerospace industry. They have spread quickly in aeronautics, sports equipment's, like tennis rackets, golf sticks, sailing yachts, and also in furniture industry [14]. The first attempts to use in the furniture industry have been known since 1948, with the development of glass fibre-polyester armchairs.…”

Abstract. Based on different design processes for innovative products, the paper presents a new approach of the process. The new method studies the problem of replacing the wooden components of the resistance structure of furniture with other materials. This is a reverse engineering process, that starts with the entire component, following a series of steps to the part drawings, ready for manufacturing. The method was validated by redesigning some parts of the upholstered products manufactured by TAPARO Company, by replacing the wooden parts of the resistance structure of sofas with composite material.
