摘要：
Shrinking of partially cured or B-staged resin coated fabric, also known as prepreg, during C-staging or full curing is reduced by cutting at least a plurality of the warp of the fabric in at least one location before C-staging. Prepreg is useful in the computer industry in the manufacture of printed circuit boards.
