Thermal behavior and kinetics study of carbon/epoxy resin composites

Abstract: Carbon/epoxy laminates and foam‐core sandwich composites are frequently used as engineering materials within the aerospace sector. However, epoxy resin matrix and foam‐core materials are highly flammable. In this work, the thermal behaviors of carbon/epoxy laminates and foam‐core sandwich composites were investigated using thermogravimetric analysis at different heating rates in atmospheric air. The morphological images of specimens and the residue after pyrolysis at different characteristic temperatures were … Show more

“…Based on the assumption that the external heat flux q is constant and heat loss from the exposed surface is negligible, 1titalicign0.25emwas first correlated with q using different values of the coefficient n ( n = 0.5 and 1 correspond to the cases of thermally thick and thin solids, respectively). [ 9,14–17 ] To obtain the ignition time model for two kinds of specimens, Figures 3 and 4 show the effects of q on 1titalicign, with n = 0.5 and 1 for two kinds of carbon/epoxy laminate composites, respectively.…”

“…Because of the inert nature of carbon fiber, epoxy resin content is nearly the only component involved in thermal decomposition in an inert atmosphere and flaming combustion. [9] TGA was conducted using a DTG-60 (AH) thermal analyzer (Shimadzu, Japan) to identify epoxy resin matrix content in laminate composites. VB-C/ELC and A-C/ELC were tested separately with a nitrogen flow rate of 50 mL min −1 at a heating rate of 20 C min −1 within a temperature range of room temperature to 1000 C. The mass for all block specimens was 5.5 ± 0.2 mg.…”

“…Differential scanning calorimetry (DSC) has been used to investigate the kinetics of cure process under dynamic [24,25] and isothermal [26,27] modes. Many kinetic models have been used to study kinetic parameters, such as Kissinger [28,29], Ozawa [30,31], Kissinger-Akahira-Sunose (KSA) [32,33], Flynn-Wall-Ozawa (FWO) [28,34], Kamal [35,36], autocatalytic [37,38], and Borchardt Daniels [39,40] methods.…”

“…Among the combustion gases, next to H 2 O and CO 2 , hydrocarbons, HCl, and different aromatic compounds were detected. 32 Within this work, cone calorimetry is used to investigate the fire behavior of sandwich structures made of modified bottle grade PET foam cores and epoxy resin face sheets. Polyesters are known for their low melt strength and therefore often need to be chemically modified to improve the foamability.…”
