アルミニウム合金製の被着体を用いたアクリル系接着剤強度の温度および負荷速度依存性の評価 Evaluation of temperature and load rate dependence for strength of an acrylic adhesive resin in aluminum alloy joints
An impact test equipment was developed. This equipment is able to produce comparatively low load rate of impact. The impact strength of the acrylic adhesive under low temperature was measured using the developed impact test equipment. By using aluminum alloy as adherend, the equipment can measure the impact strength of acrylic adhesive. The tensile strength of the adhesive under various load rate and low temperature were measured. Conventional equipments were also used for these tests. Relations between the load rate, the test temperature and the tensile strength of adhesive were investigated. As an experimental result, at any case of load rate the tensile strength of the acrylic adhesive increased once with temperature decrease. However, when the temperature decreased lower than a specific value, the strength of the adhesive decreased. The temperature that the strength of the adhesive becomes maximum rises with the increase of the load rate. The change of strength of the acrylic adhesive is influenced by the viscosity of the adhesive itself.
