Abstract

Et fiberarmert komposittskall (2) med 1 polymermatrise skal benyttes til å dekke elastomerlaget (38) som omgir antennen (36) til et formåsjonsevalueringsverktoy til måling under boring i et borehull. Skallet (2) beskytter elastomerlaget (38) og den tilhørende antenne (36) mot slitasje og abrasjon. Hvis det ødelegges under boring, kan skallet (2) erstattes : på borestedet med minimal dødtid.
