Self-reinforced polymer composite is a peculiar kind of muti-phases material. Its reinforced phase comprises the same chemical structure but different physical properties as the matrix phase being in a great value of application

owe to the significant excellent compatibility and bonding strength at the interphase of the two phases

while it seems significant beneficial for recycling. In this paper

a few preparation methods containing in-situ and out-situ ways for this material are summarized

including hot compact

overheating of constrained fibers

die-drawing

roll-drawing and other ones in details. And we also focus on summarizing the manufacture process and faults for the composite. At last

an overlook of this material’s perspective is made.
