The effective elastic modulus of the composite containing hollow spheres is investigated by differential scheme. The results what we have derived show that the moduli of the composite with higher volume fraction of hollow spheres can be predicted by this method. The modified result of Young's modulus can be used to predict the Young's modulus of the syntactic foam plastics in which some voids are included. A quite good agreement has been obtained between the experimental results and prediction of...

The effect of the content, the particle size of the hollow sphere and the coupling agent on the mechanical property of Si-Alhollow sphere/ PP reinforcing materials is investigated, and PP is reinforced by the Si-Al hollow sphere. The results shows that the notch impact, tensile and flexible properties of Si-Al hollow sphere/ PP are increased obviously when the content of hollow sphere is 0 - 40% , and the increase extent will be the highest with the content 20%. Compared with 10 μm Si-Al hollow sphere, the notch impact strength and tensile strength of 5 μm Si-Al hollow sphere reinforcing materials will reach a higher value. Moreover, the reinforced effect of Si-Al hollow sphere, which was treated by the coupling agents A and C, is more than that of pure Si-Al hollow sphere. Thus, Si-Al hollow sphere not only increases the mechanical properties of PP, also decreases the cost of PP. It brings out a new way for the application of Si-Al hollow sphere.

用刚性无机粒子硅—铝(Si—Al)空心球填充增强聚丙烯,研究了Si—Al空心球的含量、粒径及偶联剂对PP/Si-Al空心球增强材料力学性能的影响。结果表明,填充40%以下的Si—Al空心球的增强PP的缺口冲击强度、拉伸强度、拉伸弹性模量、弯曲强度和弯曲弹性模量均显著提高;Si—Al空心球为20%时,增强PP的冲击强度达到最大值。与填充粒径10μmSi—Al空心球相比,填充粒径5μmSi—Al空心球的增强PP的缺口冲击强度和拉伸弹性模量高。填充经偶联剂A和C表面处理的Si—Al空心球有利于提高增强PP的缺口冲击强度、弯曲强度及弯曲弹性模量。填充刚性无机粒子Si—Al空心球不仅能提高PP的力学性能,而且能降低PP的成本,为Si—Al空心球的应用开辟了新途径。
