Dataset for Transient Thermal Response of Banana–Bagasse Fiber Hybrid Biocomposite Laminates with Conch Shell Filler under Active Infrared Thermography
Description
This dataset contains raw extracted master temperature–time data and representative thermal video recordings obtained from transient convective heating experiments conducted on seven banana–bagasse fiber hybrid biocomposite laminate configurations, including neat epoxy (EP100) and filler-modified systems containing 0–5 wt% conch shell powder. Active infrared thermography was used to monitor surface temperature evolution under a standardized thermal loading protocol consisting of 30 s convective heating (approximately 100 °C hot air) followed by 60 s natural cooling. Temperature data were recorded at 1 frame per second over a total duration of 90 s. Each laminate configuration was tested in triplicate (n = 3), and the master dataset includes all replicate measurements. The dataset includes: • Raw time-resolved temperature data (0–90 s) for all seven laminate systems • Extracted thermographic metrics (T0, T30, Tmax, T90, heating rate Rh, cooling rate Rc, and thermal retention ratio TR) • Master compiled dataset used for statistical analysis • Sample thermal video files for each laminate plate demonstrating the transient heating and cooling behavior All quantitative metrics reported in the associated manuscript were derived from raw, unsmoothed temperature data. The thermal videos provide visual validation of surface temperature evolution and phase transitions during heating and cooling. This dataset supports the manuscript entitled: “Transient Thermal Response of Banana–Bagasse Fiber Hybrid Biocomposite Laminates with Conch Shell Filler Using Active Infrared Thermography.”

Steps to reproduce
Laminate Preparation Fabricate banana–bagasse fiber hybrid epoxy laminates with conch shell filler contents of 0–5 wt% using compression molding. Maintain a nominal laminate thickness of 3 mm. Cure at room temperature for 12 hours. Specimen Preparation Cut plates to 290 mm × 290 mm dimensions. Ensure flat, uniform surfaces before testing. Experimental Setup Position the laminate vertically in a non-conductive holder. Place a hot air blower at a fixed distance of 30 cm from the specimen surface. Position the infrared thermal camera at 30 cm from the opposite side. Thermal Loading Protocol Apply convective heating using approximately 100 °C hot air for 30 seconds. After 30 s, terminate heating and allow natural cooling for 60 seconds. Total observation time: 90 seconds. Data Acquisition Record thermal video continuously at 1 frame per second. Extract center-region surface temperature for each time frame (0–90 s). Repeat the experiment for three independent replicates per laminate configuration. Metric Extraction From raw temperature data, compute: Initial temperature (T0) Temperature at 30 s (T30) Maximum temperature (Tmax) Temperature at 90 s (T90) Heating rate (Rh = (T30 − T0)/30) Cooling rate (Rc = (Tmax − T90)/60) Thermal retention ratio (TR) Statistical Analysis Perform one-way ANOVA to compare groups. Apply Bonferroni correction for multiple comparisons. Use raw, unsmoothed temperature data for all statistical calculations.
