Impact tests for glued joint specimens of wood were carried out at various impact velocity (V) using a whirling arm machine (Fig. 1 and 2), and the effects of V on their strength properties were discussed comparing with those of wood adherend. Wood adherend was air-dried Taiwanhinoki (Chamaecyparis taiwanensis M & S), and flat jointed chair type and butt end jointed tensile type of test specimens were prepared for the tests (Fig. 3 a and b). Three kinds of adhesives were used, that is, epoxy resin, polyvinyl-acetate resin and urea resin. The range of V was 0. 5-20. 0 m/sec. In the impact shear test of chair type specimen, wood failure shows relatively high values in all specimens. Impact shear strengh (S1) decreases with increase of V, and this decreasing tendency is similar to that of adherend (S,) reported in the previous experiment. S, of specimen glued with epoxy resin or polyvinyl-acetate resin adhesive is stronger than Si at the equal impact velocity under 2. 4 m/sec of V, and above this impact velocity S, is equal to Si. But S, of urea resin adhesive is smaller than that of the above two adhesives, and above 2. 4 m/sec of V the ratio of S, to Si is about 0. 8. The relationship between impact fracture energy of shear specimen and impact velocity shows the similar tendencies as that of adherend. In the impact tensile test of butt end joint specimen, the fracture occurs at the glue line, and so wood failure is nearly zero in all specimens. Impact tensile strength (B3) decreases with increase of V. The ratio of B, to tensile strength of adherend (BI) is only 0.2-0.3 at 0.6m/sec of V, and this value decreases gradually according to the increase of V. Within the limits of this experiment, epoxy resin shows the highest adhesiveness for impulsive load.
