发明名称 THIN, SELF-SUPPORTING, DUCTILE, PLASTIC TARGET SHEET
摘要 A one-piece, self-supporting target made of relatively rigid, ductile synthetic plastic material having low shock transference characteristics. The target is formed with longitudinal and transverse strengthening formations, and, due to its thickness and ductility, a projectile passing through the target forms a flanged hole having dimensions less than the corresponding dimensions of the projectile.
