“…In addition the thermal decomposition of elastomers that are also present in tyre rubber has been studied in depth [11][12][13][14]. Yet so far the reinforcing fibre that is recovered as a waste in tyre shredding factories has received little attention [15][16][17][18]. The aim of the present work is to identify the fibres that are present in the waste recovered from tyre grinding factories to help in finding a use for this waste.…”

The composition of the reinforcing fibre obtained from the recycling of scrap tyres was analyzed with a view to finding the most suitable applications for it. The material (RF) was separated into two different parts i.e. fibre (F) and microfibre (MF) to ensure the maximum homogeneity of the material under study. Thermogravimetric analysis (TG) together with differential scanning calorimetry (DSC) and infrared spectroscopy (FTIR) were used to identify the polymers present in the waste and to determine in what proportions they were present. Determination of the temperatures of maximum volatile matter evolution (Tmax), the yield at the end of the pyrolysis and the melting temperatures yielded very useful results for the identification of the polymers. In order to confirm the results obtained, pyrolysis of the pure polymers was carried out and the decomposition products were analysed. The results were then compared with the oil composition data derived from the pyrolysis of the waste fibres. Our results showed the presence of two polyamides, rayon, polyester and aramid.

Fir wood flour may be used as filler in glass reinforced composites due to the lower content of tannins in comparison with oak wood flour (Cerbu et al. 2010). This work focuses on the behavior of E-glass / fir wood flour / epoxy hybrid composites in mechanical tests (three-point bending tests, and Charpy impact tests) after immersion in water for 1177, 3048, and 6572 hours. Alternating layers were reinforced either with glass fabric or with fir wood flour. After 3048 hours of immersion, the flexural properties decreased: the modulus of elasticity (MOE) in bending and maximum flexural stress σ decreased by 13.16% and 37.54% respectively, with respect to the values recorded in the case of the dried specimens. The properties recovered a little after saturation because they increased after 6572 hours of immersion: MOE was greater (4.36%), while maximum flexural stress was greater (6.78%) with respect to the values corresponding to the specimens tested after 3048 hours of immersion. In the Charpy test, the impact strength K was measured. The damage (cracks developed at matrix-glass interface) caused by water absorption is discussed in order to explain the degradation of the mechanical properties. The adding of the wood flour led to the increasing of the modulus of rigidity EI in bending and it is proved by comparing with the results obtained in case of glass / epoxy composite without wood flour. Components for outdoor furniture (gardens) could be an application of the hybrid composite analyzed in this paper.

Other hybrid composites are made of different kinds of layers that are reinforced with only one kind of fibers and layers alternate.The E-glass / fir wood flour / epoxy composites analyzed in this paper were from the last class described above because the layers reinforced with glass fibers alternated with the layers reinforced with fir wood flour. Such a hybrid composite should combine the advantages of wood fibers described below within this section (Klyosov 2007) with the advantages of the glass fibers (Cerbu et al. 2009;Zhou et al. 2013;Wang et al. 2014).Wood plastic composites (WPC) are widely used (Klyosov 2007) because the addition of the wood flour to plastics may potentially lead to material cost reductions while mechanical characteristics can be improved.
