ABSTRACT:
A sandwich panel element comprises a core 10 of fibrous material arranged between first and second parallel outer skins of generally planar sheet material 30, 32. The core material consists of a plurality of elongate strips 12a, 12b, 12c etc. arranged in side-by-side and end-to-end abutting relationship. The strips are formed so that the fibers are in a direction generally transverse to the planes of the sheet material 30, 32. The strips 12a, 12b, 12c etc. are individually shorter than the length or width of the panel element and the mutually abutting ends 25 of the strip are chamfered at an acute angle to the longitudinal direction of the strips to allow the ends to overlap.
