A Simulation Study on Bamboo Fiber Based Composite Bricks

Amerri, Ali (2021) A Simulation Study on Bamboo Fiber Based Composite Bricks. [USQ Project]


Global warming and climate change are major challenges that have developed as a result of fast industrialization, heavy use of non-renewable natural resources, and unsustainable expansion. Because of these startling consequences, they may be mitigated by introducing energy-efficient technology, notably in the building industry, which consumes 30% of the energy in industrialised nations. Instead of creating new materials, the internal composition of conventional materials, such as clay bricks, may be carefully controlled utilising natural or industrial waste to make them more energy-efficient. This is a step toward environmental sustainability. Natural fibres are widely used in the improvement of mechanical and thermal properties of building materials today due to their numerous benefits such as natural abundance, biodegradability, easy availability, flexibility, low cost, less toxicity, less density, renewability, and good adhesion with the matrix. In this study, bamboo fibres were chosen as a reinforcing agent other natural fibres such as sisal, hemp, jute, cotton, bagasse, and ramie.

In comparison to experimental methods, the Finite Element Method (FEM) is an effective tool for studying the properties of natural fibres and their composite materials. A variety of variables, such as reinforcement type, orientation, aspect ratio, and fibre volume fraction, can all influence the mechanical and thermal properties of composite materials. The finite element method was utilised in this study to build a model for the design and simulation of natural fibre reinforced clay composite bricks. These composites were tested for a variety of thermal and structural characteristics.

First, the geometry of composite bricks was created in ANSYS workbench, and then structural and thermal analyses on the developed composite bricks were performed. Due to the flexible nature of bamboo fibres, the simulation results indicated that the insertion of bamboo fibres in the clay matrix increased the normal stress and strain values while decreasing Young's modulus. Furthermore, the fibre reinforcement did not cause significant deformation in the composite under heavy load application, demonstrating the composite bricks' superior mechanical strength. Thermal analysis was performed on the proposed composites, which were tested under applied thermal loads and the conductivities of these composites were determined. The inclusion of bamboo fibre lowered the thermal conductivity of the composite brick, making it a viable building construction material that will aid in lowering the inside temperature of buildings. When compared to pure and other composite bricks, a 3% bamboo fibre reinforced clay brick composite exhibited the lowest heat conductivity.

Furthermore, the highest performing composite brick was subjected to a parametric analysis and evaluated under various structural and thermal stresses. According to the findings of this study, this material would perform better in building construction and will give high compressive strength as well as insulating characteristics.
