Factors affecting the glue strength of finger-foints in commonly used timber species in Sri Lanti;

Abstract

Finger- jointed timber production plays a vital role in furniture industry in the world. However, iss_.. related with the strength of the joints, fixing time, timber species and glue types etc, are still not r- , investigated in Sri Lanka. This research evaluated the effects of commonly available glue types, tim:r species, and time allowed to fix the joints on the strength of finger joint. The response viriables measu::: for the tension tests. Data were gathered using Universal Testing Machine. one way AN6VA was usei :. " each timber species to analyze the data. It was found that the glue type, timber species and time alloi, to fix the joints directly affect ": the glue tensile strength. Furthermore, the highest tensile strength ,,,,:", recorded in Polyvinyl Acetate (PVA] SWR glue with the allocated time period of 4 hours.
