Curing process polymer
WebThis process is displayed in an abrupt drop in the particle size (average diameter)-curing temperature curve (see Figure 6.15). ... Proteins are temperature- and pressure-sensitive polymers. Curing temperature, pressure, and time have an important influence on the final protein structure reconformation, mutual diffusion at the interface, and ... WebThe paper gives a set of basic relations characterizing the phenomena of viscous polymer resin flow through fiber reinforcement and the resin curing process. We describe the technological process of manufacturing composite structures. The influence of the resin curing process on values of residual stresses in composite constructions is analyzed …
