Phenolic resin glass fiber reinforced prepregs are highly suitable for airplane interior components due to their high fire resistance, high temperature performance, and low-density characteristics. Safran Cabin seeks to improve their storage of the phenolic resin prepreg during their manufacturing process. The issues the company faces are the occasional delamination of prepreg laminas or the loss of tackiness rendering the lamina unfit for use. The area of investigation was determining the weight loss of volatiles during out-time. The term “out-time” consists of the time the prepreg experiences in transit, on the shop floor, and in short-term temperature-controlled storage. Simulated storage conditions were investigated to three different temperature ranges that the prepreg samples experience during out-time: 2.6°C, 16-18°C, and 28-33°C. The project objective was to better understand the loss of volatiles the prepreg experiences. The volatiles under investigation are from the solvent used in the preparation and manufacturing of the prepreg. The functional groups of key volatiles in the prepreg were detected and monitored using a Fourier Transform Infrared Spectroscopy (FTIR) after different simulated storage periods within the maximum out-time of 11 days. Additionally, Thermogravimetric Analysis (TGA) was used to measure the weight loss of remaining volatiles in the phenolic resin prepregs. The end results of this project suggest that the volatile loss during out-time is more temperature dependent than time dependent.
