NATURAL FIBERS -as Subtitute for Asbestos

How strong this fiber ?  book weight is 380 gram

Sisal fibre is obtained from Agave sisalana, a native of Mexico. The hardy plant grows well in a variety of hot climates, including dry areas unsuitable for other crops. After harvest, its leaves are cut and crushed in order to separate the pulp from the fibres. The average yield of dried fibres is about 1 tonnes per hectare, although yields in East Africa reach 2.5 tonnes.

The fibre

Lustrous and creamy white, sisal fibre measures up to 1 m in length, with a diameter of 200 to 400 microns. It is a coarse, hard fibre unsuitable for textiles or fabrics. But it is strong, durable and stretchable, does not absorb moisture easily, resists saltwater deterioration, and has a fine surface texture that accepts a wide range of dyes.

Uses of sisal

Sisal is used in twine and ropes, but competition from polypropylene has weakened demand.

 

But other markets are emerging - today, sisal can be found in speciality paper, filters, geotextiles, mattresses, carpets and wall coverings.

 

It is used as reinforcement in plastic composite materials, particularly in automotive components, but also in furniture. Another promising use is as a substitute for asbestos in brake pads. (It is also the best material for making dartboards.)

By-products from sisal extraction can be used for making bio-gas, pharmaceutical ingredients and building material
