Light conductive fibers being embedded as crack monitors in reinforced compound material are protected as follows. During laminate assembly the fiber ends are slipped into relatively short teflon hoses but being provided to be at least in parts embedded in the compound parts to be made; the ends of the hoses that will be embedded are closed with a cold curing laminate resin; the fiber ends with enclosing teflon hoses will be threaded through laminate openings during assembly of the lamination, and the fiber ends with projecting hoses are also inserted in a conical bore of an assembly device; open areas and portions of the compound part adjacent to the conical bore of the assembly tool are filled with laminate resins; a protective cover is then placed onto said bore and over the teflon hose protected fiber ends prior to curing of the part; and the thus prepared part is cured in an autoclave.
