Effect of an intumescent flame retardant on the fracture toughness (Mode I),thermal,and flame-retardant properties of continuous glass fibre-reinforced polypropylene composites
To solve the ‘wicking actions’ caused by fibre, intumescent flame retardant (IFR) was introduced into the resin of continuous glass fibre-reinforced polypropylene (CGF/PP) composites. The influence of IFR on the properties of composites were investigated by a double cantilever beam test, thermogravimetric analysis, limiting oxygen index, vertical burning test (UL-94), and cone calorimetric test. The results revealed that when the content of IFR was 15 wt-%, the initial Mode I interlaminar fracture toughness (GI init.) and propagation fracture toughness (GI prop.)) were enhanced by 123.2 and 70.26%, respectively, compared to composites with no IFR. The maximum weight loss rate (Tmax) was improved to various degrees. Samples could self-extinguish with an oxygen concentration of 32.4% and achieve a UL-94 V-1 rating. Furthermore, the peak of heat release rate, total heat release, fire performance index, and mass loss rate tests indicated that IFR could dramatically enhance the flame retardancy of the composites.
