TL;DR: In this article, a survey about physical and chemical treatment methods which improve the fiber matrix adhesion, their results and effects on the physical properties of composites is presented, and the influence of such treatments by taking into account fibre content on the creep, quasi-static, cyclic dynamic and impact behaviour of natural fibre reinforced plastics are discussed in detail.

TL;DR: In this paper, the authors developed kenaf-glass (KG) fibres reinforced unsaturated polyester hybrid composite on a source of green composite using sheet molding compound process.
Abstract: The main aim of this paper is to develop kenaf-glass (KG) fibres reinforced unsaturated polyester hybrid composite on a source of green composite using sheet moulding compound process. Unsaturated polyester resin (UPE) and KG fibres in mat form were used at a ratio of 70:30 (by volume) with treated and untreated kenaf fibre. The kenaf fibre was treated with 6% sodium hydroxide (NaOH) diluted solution for 3 h using mercerization method. The hybrid composites were tested for flexural, tensile and Izod impact strength using ASTM D790-03, ASTM D618 and ASTM D256-04 standards respectively. The highest flexural, tensile and impact strength were obtained from treated kenaf with 15/15 v/v KG fibres reinforced UPE hybrid composite in this investigation. Scanning electron microscopy fractography showed fibre cracking, debonding and fibre pulled-out as the main fracture mode of composites and kenaf treated 15/15 v/v KG reinforced hybrid composite exhibited better interfacial bonding between the matrix and reinforcement compared to other combinations.

TL;DR: In this article, a newly developed system enables utilisation of short flax fibres for SMC (Sheet Moulding Compound) production, which enables flax fibre reinforced SMC materials to compete with glass fibre SMC, especially when the fibre length exceeds 25 mm.
Abstract: This paper describes a newly developed system, which enables utilisation of short flax fibres for SMC (Sheet Moulding Compound) production. It is shown that by using an evenly distributed layer of short dried flax fibres, after controlled impregnation and maturation, a homogeneous flow of the prepreg in the mould is obtained, and accordingly a flax fibre reinforced SMC can be produced. Mechanical data indicates that for applications designed with respect to stiffness, flax fibre reinforced SMC materials compete with glass fibre SMC, especially when the fibre length exceeds 25 mm.

TL;DR: In this paper, a new fluidized bed process for recovering reinforcing fibres from scrap thermoset composites is described, and the main physical properties of plaques moulded with the experimental DMCs have been measured.
Abstract: This paper describes a new fluidised bed process for recovering reinforcing fibres from scrap thermoset composites. Glass fibres recovered from scrap sheet moulding compound at 450°C using this process have a strength reduced to about half that of virgin fibre. These fibres have been used as partial and full replacement for virgin fibres in a dough moulding compound (DMC). The main physical properties of plaques moulded with the experimental DMCs have been measured. Flexural and Young's moduli are unaffected by the level of reclaimed fibre used. Flexural and tensile strength are reduced when over 50% of the virgin reinforcement is replaced by fibres recovered at 450°C.

TL;DR: In this article, the first attempt to develop a new sheet molding compound (SMC) using low cost carbon fibre (CF) recyclate as the reinforcing component in place of conventional glass fibres was reported.
Abstract: This study reports on the first attempt to develop a new sheet moulding compound (SMC) using low cost carbon fibre (CF) recyclate as the reinforcing component in place of conventional glass fibres. A newly designed manufacturing system allows large coarse recyclate fibrous materials to be utilised within existing SMC production lines, and with careful control of virgin and recyclate fibre distribution, a viable SMC grade utilising recycled CF can be obtained.
