Abstract:
Proper management of material resources is one of the biggest challenges facing humanity. This has relied on the use of waste to create new materials, which reduces the amount of waste deposited in landfills and the demand for material resources. However, the presence of moisture in the waste can affect the performance of composites. The objective of this work is to evaluate the influence of particle moisture on the compressive strength of polymer matrix composites. In this work, the matrix used was an epoxy system and the dispersed phase was chamotte and/or coconut shell powder. The formulations were evaluated in two configurations, using particles with and without oven drying. The compression test results from this work, through variance analysis, did not indicate a significant variation in the stiffness and strength of the materials, although greater porosity was observed in the test samples using particles that had their moisture removed. However, the manufacture of larger test samples may result in a greater influence of moisture on the creation of defects and consequently on mechanical properties.
