Question 1c

Mold temperature has a significant effect on the behavior and properties of the thermosetting polymeric materials. In the process of molding materials that are semi-crystalline, the most appropriate temperature must be more than the control to allow this polymer enough period to carry out the crystallization process. Figure 1c below gives the comparison of the behavior of PPA when molded using the optimum temperature and those under low temperatures. The graph provides the material with modulus as the primary function of the heat. It brings out the idea that as the temperature of the mold increases, the material stiffness at RTP increases too. However, more apparent differences between the samples at the right temperature and those of low temperatures can be at extremely high test temperatures. It can be that as the material moves closer to the transition region in the glass region that is often between 125 and 145 C; there seems to be a decline in the modulus in the molded material at the lower temperatures. This value even falls farther and at a fast pace with the farther reduction in the heat (Sahulhameedu, Chen & Shakya, 2018). The figure goes ahead to give the interaction between the melt temperatures and the mold in the determination of the impact of the ABS performance. ABS is an amorphous polymer that is typically selected to be very durable and sturdy. The mold temperature varies between 26 and 89 C. The melt temperature is adjusted from 220 to 280 C. It is amazing that the effect of resistance, in this case, ranges from less than 3 Nm.

It is significant to note that the dominant variable is the mold temperature. However, the optimum findings can be provided when elevated temperatures of the mold are harmonized with those of low melt temperatures. This right range of the situations for the processing must then be avoided to make the experiment successful. This kind of behavior is very characteristic of most polymers. As much as optimal performance is achieved by combining the low melt temperatures and the high mold temperatures, the exact opposite is often found in the actual production floor (Hussain & Palit, 2018). This notion is because the melt temperatures are regularly maintained at high temperatures to help in the reduction of the melt viscosity in the entire process. The high melt temperatures aid in the increase of the energy consumption thus degrades the polymer and then extends the time used in the cooling process before the creation of a dimensionally stable part.

Question 1d

The knowledge of the water content in clay is significant in the understanding of the tensile strength of the ceramics that would be produced at the final stage of the process. The same knowledge of the power of the ceramics is required in several sectors in the engineering field. Drying is one of the steps where the same experience is needed in the technological manufacture of the ceramics. The use of a computer is essential in this process when the right temperatures for drying are to be determined as a way of preventing damage to the ceramics. Such losses can be realized regarding deformations, thick cracks, and the part through the process. However, the knowledge of the strength of the material and other coefficients would be significant in the performing of such computer programs in one way or the other. The power of the dried materials would depend on the water content present in the clay alongside the transformations taking place during the drying process (Sahulhameedu, Chen & Shakya, 2018). The analysis of both the compressive and tensile strengths would be most appropriate in the understanding of these changes in the clay material in one way or the other. Several experiments have been carried out based on the water content in clay and the influence of the strength of the ceramic produced.

Figure 1d gives the results of the performed compressive tests on the clay materials. The strength of the clay material is often the highest among all the stuff used in the ceramic works in the dried state, but this strength reduces drastically with the introduction of water to the clay material. This property is very typical of materials with bonds connected using Van der Waals forces because the forces between the grains are weak in one way or the other. The electrochemical properties of clay have a higher tensile strength in the over dried state. However, this tensile strength reduces when water is to the material. The force then gets to stabilize in intervals of between 6% and 18% of the water or moisture content (Hussain & Palit, 2018). The surface bonds that are present between the grains do dominate over the 6% moisture content in the entire process. The ionic bonds between the grains then start to rise in concentration and dominate the material with the addition of water. Therefore, the material strength is then reduced drastically with the process of adding more water to the sample.

Question 1e

The aspect of fiber alignment in the composite material lays with the manner I which the fiber is onto the matrix of the same composite material. This factor implies that the adhesive strength of the cord onto the model plays a significant role in defining the properties and behavior of the composite material in question. The optimal level of the interfacial bond energy between the matrix and the fiber is a critical factor in the process of accepting the composite material in various uses in the engineering field. This property is significant in the performance and the features of the composite material in question. The same interfacial strength can as well be optimized when the link between the level of interaction between the matrix and the fiber is well understood (Sahulhameedu, Chen & Shakya, 2018). The strength of this relationship can then be realized using various degrees ranging from 0 to 90 based on the tensile strength and the flexure properties of the material. This knowledge would be valuable in the understanding the fracture and the mechanical adhesive properties of the fiber present in the article. The level of adhesion between these two surfaces is to the changes impacted by the increase in the shear strength of the interfacial adhesion properties. The experimental data have proved that the modifications on the fiber did not affect the flexure and tensile strength in the material. However, the maximum strains and the forces are governed and controlled by the interface properties between the matrix and the fiber. This property was with the modification of the surface of the tissue. The primary failure mode in this process is on the changes in the fiber-matrix interfacial shear strength.
