“…The predictive model (Equation 2) which was obtained by fitting the general quadratic model to the experimental results was then used to predict their corresponding responses. It can be seen that for all responses considered, the values obtained for the experimental results and those predicted by the quadratic model are very close and this is an indication of the validity of the statistical model developed [53]. The predicted results by the RSM models for the responses were validated by comparing them with the actual experimental results.…”

In this study, a five factor Box-Behnken Design (BBD) was applied to plan and perform experiments for the production of composite polyvinyl chloride (PVC) material. The Box-Behnken Design combined with Response Surface Methodology (RSM) was utilized to optimise the production variables, physical and tensile strength of composite PVC. Design Expert ® software version 7.0.0, (Stat-ease, Inc. Minneapolis, USA) was used for the experimental design. The Design Expert ® software utilizes the concept of randomization to generate the experimental design. This was achieved by scheduling the experiments in a random manner in order to minimise the effects of unexplained variability in the response. The design involved five different variables; three of which are the composite constituents (PVC, raffia palm and plantain peduncle) and the remaining two are the production variables (temperature and pressure). An assessment of the results showed that the quadratic model was suitable for modelling the responses considered in this study. The R 2 value was close to one while the standard deviation was equally small. The result of the experimental and RSM predicted results for tensile strength showed that for all responses considered, there was close similarity between the experimental results and those predicted by the quadratic model. The results of the parity plots obtained shown that there was a good fit between the model predictions and the experimental results, thus, validated. Besides, increasing the proportion of PVC resulted in a steep and significant increase in the tensile strength of the composite. Thus, the tensile strength was improved as a result of the synergistic effect of the PVC and the fiber. However, increasing the level of rattan and plantain peduncle did not result in an increase in the tensile strength of the composite and this was as a result of the low lignin content of these fiber materials. Similarly, increasing the temperature and pressure resulted in a decrease in the tensile strength of the composite pipes.

The work entailed the influence of particle size on the characteristics and water absorption resistance of avocado pear wood fiber/low-density polyethylene (APWF/LDPE) composite enhanced by pretreatment. The fiber particle of 100, 80, 60, 40, and 20 mesh (150, 180, 250, 425, and 850 µm) for the avocado wood fiber (APWF) was infused in the resin. Each particle of the fiber with fiber content of 5–25 wt% for the untreated, pretreated with NaOH, NaOH + CH3COOH, and NaOH + CH3COOH + MAPE was intermixed in the resin to produce the APWF/LDPE composites, respectively. The APWF/LDPE composites were analyzed on the properties, water absorption resistance, Fourier transform infra-red, and scanning electron microscopy. The study exhibited that mechanical properties and water absorption resistance of the APWF/LDPE composite were improved at lower particle of the fiber triggered by treatment. The best properties were confirmed at 150 µm of APWF pretreated with NaOH + CH3COOH + MAPE when compounded with the resin. These were proportional to 15.92 MPa, 0.867 GPa, 41.39 MPa, 0.662 GPa, 683 Pa, 84.04 kJ m−2, and 2.44 % for tensile strength, elastic modulus, flexural strength, bending modulus, Brinell hardness, impact strength, and water absorption resistance, respectively. The APWF/LDPE composite for NaOH + CH3COOH + MAPE pretreated is recommended for interior cabinet of an automobile.
