Hollow glass powder (HGM), mainly composed of borosilicate glass, is an important inorganic filler with low density, high-temperature resistance, good fluidity, heat insulation, and good thermal stability. Through surface modification, HGB is applied to produce the composites, consequently improving properties. The improvements are in physical properties, such as tensile strength, elasticity modulus, dimensional stability, heat distortion temperature, and low density. More previous studies on the effect of HGM in polyamide composites have been carried out. DING et al. [8] investigated the effect of HGM on the mechanical properties and melt viscosity of nylon's six parts produced on SLS. The results showed an increase in tensile strength and impact toughness, increasing the HGM content when the HGM content is less than 20 wt%.
Moreover, the melt viscosity also decreases, which was shown to positively affect the melt viscosity and the mechanical properties of sintered parts. Sun et al. [9] confirmed a positive relationship between the small particle size of HGM filler and the part properties of nylon composite. Wang et al. [10] studied the tensile strength, tensile modulus, elongation at break, sintering properties, and part density of PA12/HGM composite parts. The experiment has shown that the PA12/HGM composite had an excellent performance in spreading powder, and HGB could reinforce the mechanical properties and the warping and shrinkage deformation of PA12.
