摘要

Light construction unit comprises a core comprising a lightweight filler and a matrix material and a covering layer comprising the matrix material without the filler. An independent claim is also included for producing a light construction unit by filling a mold cavity with a lightweight filler wetted with a curable liquid binder, curing the binder to form a filler structure, replacing part of the mold with a mold having a larger cavity, filling the cavity and filler structure with a matrix material so that the matrix material infiltrates the filler structure, curing the matrix material and removing the product from the mold.
