In this paper, a continuous glass fiber-reinforced polypropylene prepreg was prepared by fiber treatment with a silane coupling agent and MAH-g-PP resin. Continuous glass fiber-reinforced polypropylene sheets were made from prepreg and PP mats by hot-pressing; they displayed exceptional performance. This paper studies the effects of maleic anhydride grafting on the polypropylene crystallinity and MAH-g-PP content in the prepreg, and the mechanical properties of the composites. The results showed that modifying PP with maleic anhydride decreased the tacticity of the polypropylene molecular chain, which reduced the crystallinity and melting point. An excellent interface formed between the polypropylene and fiber after the glass fiber was treated with a silane coupling agent and MAH-g-PP resin. The mechanical properties of the polymer materials displayed more favorable properties as MAH-g-PP content increased; the ideal MAH-g-PP content was 50%.

Abstract Halogen-free flame retardants are ideal plastic additives that meet carbon neutral requirements. In this work, halogen free flame retardant with glass fiber reinforced PA66/PPO composites were prepared by using coated red phosphorus (FRM-150B) and phosphorus-silicon flame retardant (WR6002). The mechanical properties, heat resistance, friction and wear properties and flame retardancy were carried out to evaluate the performances of composites using as structural parts that require heat resistance, dimensional stability and accuracy. It was found that the friction coefficient and wear volume of the composites were improved with the contents of glass fiber increased, as a result, PA66/PPO composites was obtained with excellent comprehensive performance when the content of compatilizer is 7%, the glass fiber was 30%, the content of FRM is 8% and the phosphorous-silicon flame retardant is 16%. The flame retardant effect of FRM-150B and WR6002 in PA66/PPO was presented in the condensed phase, the results showed that the composite material with 16% WR6002 forms a carbon layer with excellent thermal stability. On the other hand, the mechanical properties of composites were hardly affected, has important prospects in automotive components and household appliances

Aluminum Hypophosphite

Aluminum hypophosphite can be used to flame retard glass fiber reinforced polyamide 6 (GFPA6). TGIC microcapsulated AlHP (T-AlHP) and epoxy resin microcapsulated AlHP (E-AlHP) were made and put into GFPA6. The vertical burning tests and mechanical tests were taken to study the flame retardant performance and mechanical properties of the corresponding composites. Addition of either T-AlHP or E-AlHP resulted in an increased UL-94 rating and a decreased comprehensive mechanical performance. T-AlHP endowed GFPA6 a better flame retardancy than E-AlHP did. TG showed the decomposition behaviors of T-AlHP, E-AlHP, and the corresponding composites. From Py-GC/MS, the detailed pyrolysis products of flame retardants and the flame-retardant composites were identified. Finally, the properties and mechanism of flame retarded GFPA6 with these two kinds of microcapsulated Aluminum Phosphate were summarized.
