Natural Fiber Polymer Composites Technology Applied to the Recovery and Protection of Tropical Forests Allied to the Recycling of Industrial and Urban Residues

Approaches to the evaluation of the mechanical properties of single-layer composite plates made of recyclable polymeric and protein materials

“…The PVB copolymer contains vinyl hydroxyl alcohol groups that can interact with the -OH group and -C(=O)-OH groups of collagen macromolecules in the skin fibers. The interaction between these groups can create an interface that manages to transfer the stress from the PVB polymer matrix on the cryogenic fracture of the skin fibers (de Almeida Lucas et al, 2011;Wehry 2002). In the literature there are a number of studies on thermoplastic composites containing skin fibers (de Almeida Lucas et al, 2011).…”

“…The interaction between these groups can create an interface that manages to transfer the stress from the PVB polymer matrix on the cryogenic fracture of the skin fibers (de Almeida Lucas et al, 2011;Wehry 2002). In the literature there are a number of studies on thermoplastic composites containing skin fibers (de Almeida Lucas et al, 2011). Polymer matrices may include plasticized PVC, acrylonitrile-butadiene-styrene (ABS) and methyl polymethacrylate (PMMA), if the modulus of elasticity indicates different behavior.…”

“…Microfractrography of some breaking surfaces of a PVB / leather composite sample(de Almeida Lucas et al, 2011) Figure 4 below shows the results of tensile tests for PVB composite with leather fibers obtained from waste recycling. The modulus of elasticity increases considerably, with the increasing content of leather fibers in the composite.…”

“…These composites were obtained by the same process used for the preparation of PVB / wood flour composite. Although there are some gaps in the polymer matrix, probably due to the defibration of the leather waste and the agglomeration of the skin fibers, a good adhesion can be given by the continuity of the agglomeration of the skin fibers in the polymer matrix PVB (de Almeida Lucas et al, 2011). As mentioned above, good adherence is usually difficult to achieve between the thermoplastic matrix and the natural fibers, due to the differences in polarity between the hydrophilic fibers ICAMS 2020 -8 th International Conference on Advanced Materials and Systems https://doi.org/10.24264/icams-2020.I.8 (composed of collagen macromolecules) and the hydrophobic thermoplastic matrix.…”
