The microstructure of composites for ball milling time to 20 h is equiaxed grain, and when the ball milling time reaches 40 h, the microstructure transformed into lamellar grain. There is a small amount of equiaxed Cu in the composite for ball milling 40 h, all transformed into creeping Cu when the ball mill is 60 h.

The ball mill machine was then operated at a speed of 200 rpm for 24 h, and the rotation direction was altered every 2 h. After ball milling, the resultant product was washed with DI water three times, vacuum dried at 40 °C for 24 h, and labeled as BM-α-FeOOH/PBC300, BM-α-FeOOH/PBC500, and BM-α-FeOOH/PBC700.

The ball-to-powder weight ratio was selected to be 10:1 with a 400-rpm milling speed. Hexane and methanol were used as a process control agent (PCA) during composite fabrication. The effect of PCA on the composite microstructure was studied. The obtained composites were compacted by a uniaxial press under 700 MPa.
