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.
