۱٫ Introduction

It is now possible to secure the material characteristics for a diverse range of user environments by enabling a single material to exhibit various characteristics through the application of improved composite materials.1-10 Among these materials, carbon fiber reinforced plastic (CFRP) hardened along with epoxy with carbon fiber as the base has been widely used with the light metals in the modern industry on the foundation of its outstanding strength, rigidity, light weight, low thermal deformation rate, fatigue characteristics and chemical stability. Although there are the existing CFRPs composed of woven carbon fiber known as carbon fiber reinforced plastic, it is possible to manufacture products specialized to the environments of use by using the characteristics depending on the laminate angle by applying a diverse range of lamination methods through the use of the unidirectional carbon fiber. Moreover, it has the characteristic of being able to manufacture products with rigidity that are greater although they are thinner than the products composed of woven carbon fiber. However, CFRP equipped with light weight and high strength along with various other characteristics has various problems in manufacturing in comparison to the existing manufacturing method of metals. Unlike the metals that can be forged into highly complex configurations through casting, CFRP has the weakness in which it is molded for each of the component parts and bonded together. Moreover, in using the mechanical mounting method that accompanies physical contacts and pressure by bolts and rivets, etc., the structure fractures may occur due to the mountain pressure. Accordingly, the bonding methods by using thermal fusion or chemical adhesives are emerging as the means for solving such problems. The chemical bonding method by using adhesives is currently used even for the metallic materials by means of enhancing light weight. In this paper, the tensile characteristics of fiber reinforced plastic with characteristics that are different by depending on the laminate angle of the fiber and the effect of the tensile characteristics generated at the time on the detachment of an adhesive interface are investigated when the adhesives of epoxy series are applied to CFRP. For this purpose, the bonded interface is composed by using two specimens for opening mode with adhesives and the reaction force value at the displacement which happens at the detachment of bonded interface due to the forced displacement under the tensile test is calculated.
