To make available to stakeholders the requisite
technical knowledge to foreclose superfluous loss of revenue as a result of
failures associated with the use of unsuitable medium density fibre board (MDF)
engineered wood products in Nigerian economy for diverse needs due to lack of
such knowledge, their bending modulus was investigated for sustainable economic
development. Prepared and subjected to four replicates per sample according to
ASTM D1037 testing standards and as required by a universal testing machine
(UTM), the testometric testing machine were the three most sought after in
Nigerian economy following their identification. Chats on the dynamics of the
bending modulus of the samples were ensued by computer program from the data
generated. The study compares the bending modulus of MDF Hokusan, SGK Nordic
and Richard Russel, ANOVA shows highly significant differences (p < 0.0001)
between all the three as well as Turkey’s post-hoc showing differences with p
< 0.001 for all pairs. Richard Russel exhibited the highest aggregate
average bending modulus of 8697 MPa, indicating superior stiffness and
strength. MDF Hokusan had the lowest with 1296 MPa, suggesting greater
flexibility. SGK Nordic fell in-between with 7398 MPa. Analytically, statistics
show that the bending modulus for Richard Russel is just 17.55% and as much as
570.98% more optimal than that of SKG Nordic and MDF Hokusan respectively.
Bending modulus for SKG Nordic is as much as 470.79% advantageous than that of
MDF Hokusan. These findings imply varying suitability for applications
requiring strength versus flexibility. This sustainable novel technical
knowledge of bending modulus of medium density fibre board (MDF) engineered
wood products in Nigerian economy as benchmark should be utilized in the
designs, developments and constructions by biomedical, mechanical, civil
engineers and construction companies. Future research works should definitely
focus on bending modulus of other engineered wood products types yet to be
researched.
