Thermal and Mechanical Performance of 3-Phase Polymer Composite Panels for Structural Applications

Table 3

Comparison of the structural integrity and insulation of FRP panels and plywood.

	Plywood results (literature)		Experimental results		Remarks
	Value	Ref.	PPG	PPJ
Thermal conductivity (W/m·K)	0.15	[33]	0.193–0.214	0.126–0.14	PPJ has lower thermal conductivity and can offer more resistance to heat
Density (kg/m^3)	325–1050	[33]	1475	1095	The density of PPJ is comparable to plywood; therefore, weight will be the same
Flexural modulus (GPa)	8.2	Matweb	4.89–5.06	2.48–2.58	The flexural modulus of PPJ is poor and needs improvement, before use for structural application
Drop weight impact (J/g)	0.45–0.86	[34]	0.70–1.22	—	PPG offers more resistance to falling weight and can result in enhanced life
Impact strength (kJ/m^2)	10.1	[35]	24.83–43.98	8.52–10.10	PPJ and plywood offer comparable resistance to a low-velocity impact
