“…In addition, non-woven manufacturing processes allow the reintroduction of ground wastes in new nonwoven and, thus, reuse waste production, which is a drawback of nonwoven composite manufacturing [8,12]. Among manufacturing processes [13,14], three-dimensional needle-punching allows producing complex net-shape/near-net-shape preforms [15]. The design of mechanically recyclable composites involves the development of thermoplastic matrices instead of thermoset resins.…”

To date, nonwoven fabrics made with natural fibres and thermoplastic commingled fibres have been extensively used in the composite industry for a wide variety of applications. This paper presents an innovative study about the effect of the manufacturing parameters on the mechanical behaviour of flax/PP nonwoven reinforced composites. The mechanical properties of nonwoven fabric reinforced composites are related directly to the ones of dry nonwoven reinforcements, which depend strongly on the nonwoven manufacturing parameters, such as the needle-punching and areal densities. Consequently, the influence of these manufacturing parameters will be analysed through the tensile and flexural properties. The results demonstrated that the more areal density the nonwoven fabric has, the more the mechanical behaviour can be tested for composites. By contrast, it has a complex influence on needle-punching density on the load-strain and bending behaviours at the composite scale.

“…As the change of environment humidity may strongly influence the deformability behaviour of the nonwoven fabric because of the modification of the friction behaviour between the tool and the fabric [46], the samples were dried in an oven at 60 C for 30 min before being rapidly tested on the forming device. The forming stage is very rapid (within the range of 15 s), consequently the modification of friction between the tools and the fabric due to the change of environment humidity can be negligible during forming tests.…”

The use of natural fibres for technical advanced products such as composites is widely increasing with the view to reduce the impact of the material throughout its life cycle on the environment. Some work has been performed on natural fibre based reinforcement textiles for composite materials. The mechanical and the formability behaviours of woven fabrics has particularly been characterised. However, few research work concerns the forming aptitude of nonwoven fabrics despite promising preliminary studies. In the present work, the mechanical characterizations of flax-fibre nonwoven reinforcements are carried out firstly. Then the forming tests of the nonwoven fabrics are performed to quantify their formability behaviour. The tensile and forming tests showed very different mechanical behaviours in comparison to the ones observed on woven fabrics due to the non-uniformity of nonwoven fabric. The high deformation potential of the nonwoven fabrics is established. The specific behaviour of the nonwoven fabrics is studied by analysing the local and global deformation mechanisms of the reinforcement during forming. Moreover, the manufacturing defects experienced in nonwoven fabric forming are demonstrated. The slippage/damage of network is a typical problem in the nonwoven fabric forming, which depends strongly on the fibre density (area density) of fabric and blank-holder pressure.

“…Homogeneity in fiber distribution throughout the thickness of preform can be achieved using 3‐D needle punching process. [ 103 ] Authors also concluded that the mechanical properties were decreased in case of both 3‐D and 2‐D needle punching processes. Although, needle punched preforms are inferior to most of their counterparts in terms of tensile properties, they offers some freedom of material selection to suit an application with more isotropic properties along with high interlaminar toughness.…”

Effect of reinforcement architecture on the macroscopic mechanical properties of fiberous polymer composites: A review

2020

In order to curb the fuel consumption and corresponding CO2 emission, defence, automobile, and aerospace industries are leaning towards the use of light weight‐high stiffness engineered materials like fiber reinforced polymer composites (FRPCs). One of the major advantages of FRPCs is that various properties (stiffness, tensile strength, flexural strength, etc.) can be tailored according to requirements of the application. Architecture of the reinforcement used in FRPCs has been proved to affect these properties substantially. Composite materials have seen a lot of advancement in the field of reinforcement architectures starting from the plain‐woven fabrics to advanced 3D braided/woven preforms. The architecture of reinforcement must be wisely selected to design the required properties of developed composites and to reduce the overall cost without compromising the performance. The problem addressed in the present study is the selection of reinforcement architecture while developing a composite material. 2D Plain woven reinforcements are better than other reinforcements in terms of in‐plane properties but their out‐of‐plane properties are very poor. Therefore, advanced architectures like 3D woven fabrics, 5D Braided preforms, knitted preforms, and 3D needle punched fibers are being used in various high performance applications. The present article is an attempt to analyse the effect of various available architectures of reinforcement on the macroscopic mechanical properties of FRPC laminates and to propose a systematic way to select a reinforcement.
