Achieving Sustainable Development through Nigerian Economy Marine Board Engineered Wood Force-at-Yield Evaluation

Evaluation of marine board engineered wood products in Nigerian Economy Force-at-yield was conducted on the three most commonly used samples with the objective of providing technical guidance for material selection for sustainable economic development, as a result of unavailability of the requisite technical data to obviate the usual superfluous deprivation of earnings due to failure associated with using different inappropriate marine board engineered wood makes. In conformity to ASTM D3043 standard and requirement with the testometric testing machine, four force-at-yield tests were conducted per sample, and digital aggregate average values reported. Stemmed from computer program utilizing the data generated were plots on the dynamics of the force-at-yield of the samples. Super-Plex exhibited the highest mean force-at-yield of 1460.7±0.18N followed by Marine Plex at 403.1±0.17N and Nplex at 173.6±0.17N. Precision is excellent across all samples with low variability, CV<0.10% meaning that the test was repeatable and sample preparation consistent. Results showed statistically significant differences in force-at-yield among samples F(2, 9) = 51,989,700, p < 0.0001. Post-hoc Tukey HSD tests confirmed that all pairwise comparisons were significant at p < 0.0001, with effect size analysis using Cohen’s d showing extremely large practical differences between samples with Super-Plex outperforming Marine Plex and Nplex by factors of 3.6 and 8.4 respectively. It is concluded that Super-Plex marine board exhibits the highest resistance to yield, followed by Marine Plex and then Nplex. Biomedical, Metallurgical, Mechatronics, Chemical, Mechanical, Civil, Materials, Production engineers and construction companies as benchmark should value this novel sustainable technical knowledge in developments of their designs and constructions. Force-at-Yield of other engineered wood products types yet to be researched warrants timely action.
