Improving Mechanical Properties of Wood Composites Using Basalt Glass Powder and Basalt Fiber

Abstract:

This study evidently indicated that basalt glass powder is not only far cheaper than chopped basalt fiber, but also has better reinforcing effect than basalt fiber in terms of key mechanical properties. Basalt glass powder and chopped basalt fiber were mixed with fir sawdust to produce wood composite panel, at the mass ratios of 0%, 5%, 10%, 15%, 20% and 25%. Compared with the unreinforced wood composite, the tensile and bending strengths of panels reinforced by basalt glass powder increased up to 94.3% and 43.3% respectively, when the powder contents were 15% and 10%; the ultimate increase of tensile and bending strengths were 50.8% and 34.4% respectively, when the content of chopped basalt fiber was 10%.
