FIBER-REINFORCED PLASTIC PANEL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/220160
Kind Code:
A1
Abstract:
Provided is an FRP panel material (PM) comprising reinforcing fibers (F) oriented in a pre-determined orientation direction in the vicinity of a surface (E). A plurality of either or both of protrusions (1) and recesses (2) that have a regular triangular pyramid (10) shape congruent with each other are provided on the surface (E) of the panel material (PM). The base (11) of each regular triangular pyramid (10) is disposed such that, on a reference plane (R) along the surface (E), there are no gaps and no overlaps, and each vertex (13) of the equilateral triangle (12) constituting each base (11) is shared as a vertex (13) by six bases (11). Each orientation direction of the reinforcing fiber (F) is parallel to any ridge line (14) of the regular triangular pyramid (10) viewed in the thickness direction of the panel material (PM).
