Characterization of Structural Epoxy Adhesives

摘要: A rational approach to improved fuel efficiency in vehicles includes tailoring the use and selection of materials so that structure is optimized for functionality weight, while maintaining structural integrity crashworthiness. The success multi-material assemblies depends on appropriate joining techniques provide necessary structural, fatigue crash strength; which made possible by using adhesives instead traditional methods. Effective such a challenging application requires complete mechanical data support design requirements. response toughened epoxy adhesive was investigated under varying strain rates load conditions. Differences modulus elasticity as well mechanism failure were present between tensile, compression shear modes loading. Strain affect both tensile material, but rate dependency not same two loading, being lower possibly non-linear data. identified with 29 % difference quasi-static dynamic (0.77 100 1/s). This study demonstrates loading required characterize adhesive, corresponding requirements constitutive models numerical implementations.
