Due to the increased use of adhesively-bonded FRP as a result of the inherent advantages afforded by bonded rather than mechanically-fastened joints (particularly the alleviation of stress risers and stress cracking), there is a need for tests by which joints of various FRP substrates and adhesives may be compared. This test method is intended to meet such a need.
Additional information on significance and use may be found in Guide D 4896
1.1 This test method describes a lap shear test for use in measuring the bonding characteristics of adhesives for joining fiber reinforced plastics to themselves and to metals. The method is applicable to random and fiber oriented FRP.
1.2 This test method is intended to complement Test Method D 1002
