A method is described for measuring the glass transition temperature (Tg) of epoxy joints bonding ceramic (SiC) substrates. This method is based on the strain measure of a single-lap joint subjected to a temperature variation. The resulting displacement (d) is observed as a function of the temperature (T) by means of a contact strain gauge extensometer. Thus Tg value can be determined using (d-T) curves recorded. The influence of joint parameters (joint thickness and overlap length) and of other parameters such as the applied load and the surface state of substrates were studied for a structural epoxy adhesive showing different thermomechanical behaviours. The results show that it is possible, with appropriate experimental conditions, to measure Tg with this method and to find Tg values similar to those found by classical techniques such as the static thermomechanical analysis (TMA) and the differential scanning calorimetry (DSC). This method shows similarities with TMA, but it has the advantage to allow the thermomechanical analysis of adhesives without destructive sampling of joints.

 Penelitian ini bertujuan untuk menyelidiki pengaruh pressure level terhadap kekuatan geser sambungan single lap joint (SLJ) antara Al 2024 dan CFRP dengan adesif epoksi/serbuk Al. Variasi pressure level yang digunakan adalah 0,6; 0,7; 0,8; 0,9 dan 1 MPa. Pembuatan dan pengujian spesimen uji geser mengacu pada ASTM D 1002. Hasil penelitian menunjukkan bahwa pressure level dapat meningkatkan kekuatan geser sambungan. Pada variabel pressure level terbaiknya yaitu 0,9 MPa menghasilkan kekuatan geser tertinggi (8,59 MPa). Pada kondisi tersebut, penampang patahan menunjukkan jenis kegagalan kombinasi antara kegagalan cohesive, light fiber tear dan fiber-tear.Kata kunci— pressure level; epoksi/serbuk-Al; kekuatan geser; single lap joint .
