Stream change learning is research material flow and metabolic a science. Stream change all sorts of learned flow that study the object involves nature happening and be out of shape process, permeate a lot of technology domains extensively consequently: From the earth board piece treatment of process of exploitation of drift, atmosphere, earthquake, oil, chemical industry, food, wait to the metabolism of organism and haemal circulation all the time, it is a very main subject. It is thermoplastic no matter shape plasticly process, sex of hot still solid shapes plasticly process, need to heat to melt, flow shapes and cool solidify 3 basic measure. Can say, almost in the process that all polymer make a product in treatment, want to involve flow, if note model, tool set, blow model, pressure delay, crowded go out and fibre glass twines oxygen of annulus oxygen mould, annulus, fibre glass pulls annulus oxygen goods of crowded, lamination, action of going from place to place is very accordingly significant, not only the influence machines behavior, and the mechanical performance that still can affect end item. The treatment that this chapter discusses epoxy resin only flows change learn, change to facilitate reader understanding and the treatment that master epoxy resin flow learn, we above all from stream change learn fundamental concept to tell case.
