It is based on work carried out on two fibrous materials, a barkcloth material (Rwawiire et al. 2017) and a hemp wool (El-Sawalhi et al. 2016).
We are aware that the fibres are not perfectly parallel (Lei et al., 2018) and that their orientation can have an influence on the thermal conductivity (El Hachem et al. 2017), but in this paper, we take this assumption that remains acceptable in a first approximation.

Dasgupta et al
Dasgupta et al. [3] showed that strain concentrations near an embedded optical fiber are highly dependent on the thickness and material properties of the coating.

Sigitas Vangelis et al., (2004) [1] investigated the performance of materials made of isolation cellulose resulting a density of 53 kg/m3.
Yachmenev et al., (2009) [3] conducted a research on the thermal property for isolation from Kenaf and Cotton composite for Automotive Application and found a density of 93.9 kg/m3.
Garbagnati P. et al., (2012) [4] conducted a research on the development of panels by porous cellulose isolation, by using a 50%-paper and 50%-PCM composition and found a thermal conductivity and a density of 0.063 W/m K and 215 kg/m3, respectively.
