Plug Repair

Friction plug repair welding technology has been demonstrated to be effective to repair the glass fiber-reinforced polyamide 6 sheets in the present paper. Influences of repair hole geometries and parameters on joint morphology and mechanical performance were investigated. Results showed that defect-free repaired joints were produced with the utilization of tapered holes rather than cylindrical holes. Process parameters exerted significant influences on the cross-sectional profile and morphology of the joints. Defect-free repaired welds with larger stir zone thicknesses were produced with the proper increase of rotational speeds, but excessive rotational speeds caused the formation of cavities along the plug boundary and the reduction of stir zone thicknesses. The fluctuation of the wavy bottom interface increased under larger plunge rates and incomplete connections between stir zone and base material were observed under plunge rate of 25 mm/min. Extended dwell time led to larger stir zone thickness and improved joint morphology. Tensile tests showed that the strength of the repaired joints increased and then decreased with the enlargement of rotational speeds. Decreased plunge rate and extended dwell time led to promoted joint mechanical performance. Three failure modes were observed, which corresponded to low, middle, and high repaired weld strengths.

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.
