Abstract
A pinmat () for perforating a composite laminate sheet (). The pinmat () includes a mat portion () and a series of pins () extending from the mat portion (). Each pin () has a shank portion () extending from the mat portion () and a tip portion () extending from the shank portion (). The tip portion ()includes a base portion () extending from the shank portion (), an accelerating portion () extending from the base portion (), and a piercing portion () extending from the accelerating portion (). The piercing portion () is utilized for penetrating the composite laminate sheet () within a substantially low range of applied pressure for forming a hole within the composite laminate sheet (). Moreover, the accelerating portion () is utilized for penetrating the composite laminate sheet () at a substantially high speed for forcing the base portion () into the composite laminate sheet () within the substantially low range of applied pressure. The base portion () enlarges the hole formed by the piercing portion ().
