Polylactide (PLA) is a biodegradable polyester with a wide range of applications in transportation and construction industries. In this study, the physical and mechanical properties of low void fraction PLA foams and high void fraction PLA composite foams were examined after their fabrication using the high-pressure foam injection molding (HPFIM) process. A thermal constants analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results ...
The structural integrity of steel members is jeopardized when fire insulation is partially lost. This paper examined the thermal and mechanical properties of fire insulation under elevated temperatures to further understand thermal gradients and develop preventative safety measures. A thermal analyzer measured the thermal conductivity of the insulation material using the transient plane source (TPS) method. Results show that thermal conductivity increases with temperature because the spray-applied fire resistance materials ...
Despite its fragility, poor thermal properties, and high water sorption rates, polymethyl methacrylate (PMMA) is commonly used in denture fabrication. This study aimed to examine how the addition of Aluminum oxide nanoparticles affected the properties of PMMA. A thermal constant analyzer measured the thermal properties of the Al2O3 nanoparticles using the transient plane source (TPS) method. Results showed that the thermal conductivity and thermal diffusivity of acrylic resin improved ...
Lignin and phenol are inexpensive naturally derived resources that can be used to produce cost-effective organic gels. This paper aimed to examine the thermal properties of insulative organic aerogels and cryogels made from lignin and phenol. A thermal analyzer (TPS) measured the thermal conductivity of the gels using the transient plane source (TPS) method. Results showed that, as expected, thermal conductivity increased with bulk density. Cryogels were found to be ...
Understanding the pyrolysis model for medium density fibreboard (MDF) is important for infrastructure fire safety. The purpose of this study was to determine the thermophysical properties of charred and uncharred MDF. The thermal conductivity of these inhomogeneous fibreboards was measured using a Thermal Constants Analyser in conjunction with the transient plane source (TPS) technique. Results showed that the experimental results were in good agreement with literature values, and specifically, the ...
