Characterization of an adhesive bonding between continuous fiber reinforced thermoplastic (CFRTP) composites and vulcanized rubber under a shear load

Abstract

 The aim of this paper is to study and to propose a methodology 
to test and characterize a bonding joint between rigid 
substrates made of Continuous Fiber-Reinforced Thermoplastic 
Composites (CFRTP) and over injected vulcanized rubber under 
a shear load. The EU agreed on a compromise to enforce stricter 
rules on CO2 emissions for the automotive industry, which 
has led cars manufactures to be focused in a lightweight car 
body policy by using CFRTP materials. Therefore, the behavior 
of the different kind of joints in these new materials has to 
be studied. The test defined in this paper is based on a single 
lap joint concept in which a shear load is applied to the 
sandwich sample in order to characterize the maximum loads 
and to analyze the different types of failures produced. The 
methodology defined has been applied on a wide range of test 
samples made of different element combinations in order to 
confirm that the methodology can be used as a generalized 
guideline to characterize all the variety of rubber-CFRTP 
bonding joints combinations regardless the materials and 
additives used.
