 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 .

Abstract In this paper, the energy dissipation in a bolted lap joint is studied using a continuum microslip model. Five contact pressure distributions compliant with the power law are considered, and all of them have equal pretension forces. The effects of different pressure distributions on the interface stick-slip transitions and hysteretic characteristics are presented. The calculation formulation of the energy dissipation is introduced. The energy dissipation results are plotted on linear and log-log coordinates to investigate the effect of the pressure distribution on the energy distribution. It is shown that the energy dissipations of the lap joints are related to the minimum pressure in the overlapped area, the size of the contact area and the value of the power exponent. The work provides a theoretical basis for further effective use of the joint energy dissipation.

The work presented here is a collaborative approach to achieving a reliable gas tight seal in fiberglass reinforced plastic (FRP) flanged joints using expanded polytetrafluoroethylene (ePTFE) gaskets. There are many advantages to incorporating FRP flanged piping systems in today’s chemical process industry plant build. As regulations on reliability and fugitive emissions become stricter, it is more important than ever to eliminate possible damage and leak paths at the flanged connections in these systems. This paper details a case study on a collaboration between a chemical plant operator (end user), an ePTFE gasket manufacturer, and a FRP piping original equipment manufacturer. Over a twenty-four month period a FRP flanged system was designed and validated using a custom FRP stub and ring, also known as a lap joint, flange with an ePTFE gasket. The result was the development of a FRP bolted flange system that successfully achieved a reliable gas tight seal for aggressive chemicals. Beginning with a theoretical model and ending with experimental lab analyses, the conclusive results are included herein.
