### Tensile Strength  
As illustrated in Figure 6, the correlation between HSO content and the mechanical properties of biocomposites demonstrates that an elevation in HSO content is associated with a reduction in tensile strength and a notable enhancement in strain values. This suggests that while the material displays increased elasticity, its strength is simultaneously diminished. The saturation of carbon-carbon double bonds by HSO results in the formation of more flexible structures within the matrix, which consequently weakens the material's overall strength. Conversely, an increase in CPP content has been observed to result in a corresponding increase in crosslinking density, which in turn enhances the tensile strength of the biocomposite. It is therefore evident that an optimal balance between HSO and CPP is crucial to achieve biocomposites that offer both flexibility and adequate mechanical

Equations (5) and (6) present the quadratic models proposed by the RSM design for tensile strength and strain, respectively. \[ \begin{array}{c}\text{Tensile strength = +4.73091 - 0.289826 \times CPP - 0.219456 \times HSO + 0.031227}\\ \times\text{MDI - 5.32743 \times 10 - 16 \times CPP \times HSO - 1.90719 \times 10 - 16 \times CPP \times MDI - 4.60682}\\ \times\text{10 - 16 \times HSO \times MDI + 0.003603 \times (CPP)^{2}+0.021203 \times (HSO)2+0.000327 \times (MDI)^{2}}\\ \text{Strain = +12261.55041 - 613.48711 \times CPP + 455.31565 \times HSO - 7.06459 \times MDI}\\ -\text{10.74444 \times CPP \times HSO - 0.10 \times CPP \times MDI - 0.10 \times HSO \times MDI + 7.83029 \times}\\ \text{(CPP)^{2}+8.96629 \times (HSO)^{2}+0.140081 \times (MDI)^{2}}\\ \end{array}  \tag{5}\]  
As evidenced in Table 6, the results of the ANOVA clearly demonstrate the impact of various factors on tensile strength and strain parameters. With regard to tensile strength, the HSO (B) factor is identified as exerting the most significant effect (F = 397.53, \(p\) < 0.0001), followed by the MDI (C) factor, which also demonstrates a notable impact (F = 233.35, \(p\) < 0.0001). Nevertheless, the impact of the CPP (A) factor is relatively constrained (F = 8.30, \(p\) = 0.0236). The effects of binary interactions (AB, AC, BC) are not statistically significant, indicating that the factors independently influence tensile strength. With regard to strain, the ANOVA analysis once more identifies HSO (B) as the predominant factor (F = 2330.70, \(p\) < 0.0001). The CPP (A) factor also plays a significant role (F = 660.96, \(p\) < 0.0001), whereas the MDI (C) factor is found to have no significant effect (F = 1.86, \(p\) = 0.2150). It is noteworthy that the AB interaction has a significant impact on strain (F = 233.60, \(p\) < 0.0001). Furthermore, the quadratic effects of both HSO (B\({}^{2}\)) and CPP (A\({}^{2}\)) are highly significant (F = 214.25, \(p\) < 0.0001 and F = 163.40, \(p\) < 0.0001, respectively), indicating that the impacts of these factors on the biocomposite's properties are nonlinear and complex.
