<p>A core part (10) for use in forming a structure is in the general form of a lattice-like sheet having a length and breadth much greater than its thickness and incorporating male zones at (12), which are prominent, and female zones at (14) which are recessed. The arrangement and form of the male and female zones (12, 14) are such that two core parts can be brought together to fit with their surfaces being contiguous across substantially the whole of their areas, the assembled structure therefore forming a solid panel, without voids. Reinforcing means, such as fibre strands or mats are located between the core parts as they are brought together, so that they are located at the boundary between the core parts in the finished structure.</p> |
