Caracterización físico-química de la fibra de Guadua angustifolia Kunt

This work carries out a characterization of the technical bamboo fibre of Guadua, in comparison to man-made and other natural fibres, with the aim of using this type of material as an alternative for both the Colombian, the regional (South American) and export markets (to the industrialised countries).
The use of the technical fibres of bamboo, and particularly of Guadua in Colombia, opens up vast perspectives for the use of this raw material in applications other than the construction world as is now largely the case. Although Guadua bamboo is already processed in Colombia into engineered products such as laminated Guadua (colguadua), the innovation of using technical fibres as an alternative to fibre glass and analogous products is completely in line with a variety of studies into the use of natural fibres, such as bark fibres like flax and jute, to make composites with a sustainable image. Figures reveal that the production of Guadua bamboo lies in the region of about 15 cubic m. per ha per year, which signifies huge potential for both natural Guadua and for plantations. Production capacity like this, in combination with its use as a technical fibre in high-quality composites for the car industry, for example – by analogy with activities in non-developing countries –- is highly relevant to the development of a raw material-to-final product chain in Colombia.
The consideration of the possibilities of using the technical bamboo fibre in a similar way to strong natural fibres like flax is new and very useful as an alternative route for the use of this raw material. The comparison with other fibres on the basis of specific strength is highly advantageous in view of the self-weight of composites.
