Nigerian Market High Density Fibre Board (HDF) Engineered Wood Energy to Break Appraisal for Sustainable Economy

Energy to break of the three most used high Density Fibre Board (HDF) engineered wood products in the Nigerian market Sinoply, Joubert and Dabar were investigated with the objective of providing technical guidance for material selection to support sustainable economic development. In accordance with ASTM D1037 standard and requirement with the testometric testing machine, a universal testing machine (UTM), four energies to break tests were conducted per sample, and aggregate average values reported. Plots on the dynamics of the energy to break of the samples were ensued by computer program from the data generated. Advanced statistical analysis of variance (ANOVA) result between groups, SS = 284.626, within groups SS =0.000597, F-statistic of F=5881.91 and p-value of p<0.001 showed a significant difference between the groups. Turkey’s (HSD) post-hoc result between Sinoply and Joubert, Sinoply and Dabar and Joubert and Dabar show a significant difference with p<0.001 each respectively. All pairs differ significantly. Sinoply attained the highest energy to break of 10.88725N.m, as the toughest implying high impact resistant and most durable, Dabar is in-between with 0.67175N.m to balance toughness and brittleness while Joubert has energy to break of 0.588N.m as the most brittle best suited for applications where toughness is not much of a concern. These findings imply varying suitability for applications requiring toughness versus brittleness. This study concludes that Sinoply exhibits the highest energy to break, followed by Dabar and Joubert, and recommends the application of these findings in engineering and construction practices as the sustainable novel technical knowledge as benchmark should be utilized in the designs, developments and constructions by biomedical, mechanical, civil engineers and construction companies. Other engineered wood products types yet to be researched should receive research attention in due course with regards to their energy to break.
