During last three decades, the global need for affordable housing has stimulated extensive research on cementitious matrix composites 1-18. Different groups in tropical regions have conducted an important effort on the study of cementitious composite materials reinforced with vegetable fibres 1-6,12,16. Indeed, vegetable fibres offer a cheap and sustainable approach that can be used to reduce the overall cost of construction materials and electricity consumption. The goal for developing such alternative technologies is to promote sustainable building materials. Brazilian and Guadeloupean research groups have accumulated important knowledge on tropical vegetable fibres. This fundamental knowledge on non wood tropical plants can be useful for numerous applications such as fibre cement, green composites, particle boards and papermaking 5,19-24. The fibre reinforcement is necessary to improve mechanical properties of a given building material, which would be otherwise unsuitable for practical applications. A major advantage concerning fibre reinforcement of a brittle material (e.g., cement paste, mortar or concrete) is the composite behavior after cracking. Post-cracking toughness enhanced by fibres in the material may allow large-scale construction use of such composites 21. There are two approaches for the development of new composites. The first one is based on the production of thin flat or corrugated sheets of asbestos-free fibre cement. These components are produced by wellknown industrialscale processes such as Hatschek or other similar methods commercially used with high acceptance for building
