The following 4 types of board were fabricated in this experiment.
UD: Uni-directionally oriented homogeneous board
RD: Randomly oriented homogeneous board
OC: Cross orient three-layer board with cross core layer
OR: Oriented three-layer board with random core layer
The layer construction with a face: core: face ratio of OC and OR types were
fabricated 25:50:25.
Manufacturing specifications for the boards were the following.
