Jw. Cook et al., THE ADHESION OF NATURAL-RUBBER TO STEEL AND THE USE OF THE PEEL TEST TO STUDY ITS NATURE, International journal of adhesion and adhesives, 17(4), 1997, pp. 333-337
The peel test has been used to study the adhesion achieved between a s
imple natural rubber compound and mild steel by injection moulding in
the presence of a commercial bonding system. Peel energies were calcul
ated from the peel force results by allowing for the elastic energy st
ored in the detached rubber strip. The peel energy was found to be ins
ensitive to the changes of peel rate evaluated in this work. Peel ener
gy increased by a factor of about five as the peel angle increased fro
m 30 degrees to 90 degrees. The locus of failure was cohesive within t
he rubber, but moved more deeply within the rubber and produced a seve
rely torn fracture surface. (C) 1998 Elsevier Science Ltd. All rights
