Therefore, the options a)-to transfer stress to the other phases b)- to protect phases from environment, are both correct.
Explanation:
A composite material is made by mixing two or more materials of different physical and chemical properties. The characteristics of the resulting composite material is different from the properties of the constituting materials.
The two main constituting phases of a composite material is the binder or the matrix and the dispersed phase (reinforcement).
The main function of matrix in a composite is to protect the fibers from any environmental damage and transfer stress to the other reinforcement phase.
The results of a percolation test will determine if there is suitable drainage and the size of the drain field that will be required for a septic system.
System analysis can be defined as a deep analysis of a part of the structure of a module that has been designed before. System design means to make any module or a part of the structure from scratch and build it completely without estimation.
