Characterization of a composite based on tannin resin.

The tannin extract of was used in the preparation of a 3 % paraformaldehyde resin for the manufacture of particleboard. This tannin is of the procyanidin type associated with furan residues. The modulus of elasticity of the resin obtained after the thermomechanical analysis is 3825 MPa.

Investigation of the performance of needle-punched nonwoven fabrics using and thermoplastic fibers, compared to other commercial bast fibers used in preformed biosourced composites.

In an attempt to increase biodiversity in natural plant fiber nonwovens, new sources of natural fibers must be discovered. Nonwoven fabric is a promising commercial product for upgrading the new bast fiber (TCF) and giving it an opportunity to be used in composite nonwoven applications. Two types of TCF nonwoven mats blended with polylactide fibers for one and polypropylene fibers for the other at a mass ratio of 50 : 50 were manufactured using carding and needling technology.

Chemical extraction and its effect on the properties of cordleaf burbark () fibres for the manufacture of textile yarns.

Tropical (TC) fibre extracted from the equatorial region of Cameroon has been characterized as a potential fibre for textiles. An investigation of extraction parameters to soften this fibre is crucial to use it as a biobased material in the spinning process. To obtain textile quality fibres, 34 sodium hydroxide extraction tests were carried out to study the effect of extraction conditions on its characteristics.
