Natural Fibrous Materials

Structural Natural Fibrous Materials

In some cases, economics or available resources are such that use of natural materials in building structure is necessary. Actually, as roofing or walls, in some ways it can be safer since it is not as heavy and thus will not cause as much damage if the building collapses or breaks from water force.

What is important is to ensure that joints are well connected. In below image the connection points and joints are only minimally adhered, which could cause the whole structure to collapse quickly.

A well structured natural materials based building actually might have a fair amount of flexibility which could help in an earthquake. However, they are also not strong, particularly against lateral forces such as incoming flows of water from a tsunami. Then again though the debris they may cause if they collapse could be less dangerous in flowing water than larger, heavier items.

Natural Fibrous Materials in Concrete

Natural fibrous materials can be used in concrete (fiber-reinforced concrete). Fibrous materials can actually add to the structural integrity of concrete. However, they need to be added in very small amounts due to their natural degradation and deterioration. One example of a natural fiber used in this fashion is that of coconut.
