Flexural Strength Appraisal of Marine Board Plywood in Nigerian Market

Abstract: Flexural strength appraisal of marine board plywoods in Nigerian market was conducted in a bid to provide relevant technical insights to obviate the superfluous deprivation of earnings frequently encountered with failures when inept marine board plywoods are used for diverse needs due to lack of such knowledge. Painstakingly in a diligent and elaborate approach, the most frequently used as well as common ones across Nigeria markets were identified out of which the first three were selected and subjected to test to establish their bending strength at peak or ultimate bending strength. As required by the testometric machine, the materials were conditioned and tested. Plots of flexural strength versus the associated strain were obtained with computer program from data generated. Analysis show that Marine Plex marine board plywood had the least ultimate bending strength of 17.96 N/mm2 while Nplex marine board plywood recorded 21.502 N/mm2. Super Plex marine board plywood had the best flexural strength at peak of 65.84 N/mm2. Super Plex marine board plywood recorded 0.8516 % strain, Nplex marine board plywood recorded 0.3875 % strain while Marine Plex marine board plywood recorded 0.2471 % strain at their ultimate bending strength. This revelation comparatively reveals Super Plex marine board plywood as the best in Nigerian market based on their flexural strength forbearance. Construction firms and individuals should utilize this novel insight to forestall unwarranted loss of resources arising from marine board failures due to lack of this knowledge. Attention in future should be geared towards a similar research on high density fiberboard (HDF) and medium density fiberboard (MDF).
