Chopped Basalt Fiber

Wood composite is weak under heavy loadings, which was improved by reinforcing basalt fibres. In this study, chopped basalt fibres with different lengths (5mm, 10mm, 15mm and 20mm) were mixed with fir sawdust at 2.5%, 5%, 7.5% and 10% weight fractions to produce basalt fiber reinforced fir sawdust panels. The reinforced panels showed improved strength values. A maximum bending strength value of 44.1 MPa was obtained when the mean length of chopped basalt fiber was 15mm and the weight fraction was 2.5%. The tensile strength reached a maximum value of 17.4MPa when the mean length of basalt fiber was 10mm and the weight fraction was 10%. Compared with the unreinforced fir sawdust panel group, the reinforced panel group increased bending strength 60.7% and had a 47.5% increase in tensile strength. These findings demonstrate that basalt fibre has very promising prospects for strength improving.

Polypropylene Composites

In this study, the compression molding process parameters for the development of silk fiber-reinforced polypropylene composites was optimized using Box–Behnken experimental Design with response surface methodology. The trimmed silk fibers from shuttleless loom silk selvedge waste were used as reinforcement in polypropylene fiber matrix. The process parameters of compression molding such as temperature (165–185℃), time (7–15 min) and pressure (35–45 bar) were optimized with respect to the mechanical properties of the silk fiber-reinforced polypropylene composite. The optimum parameters for better mechanical properties were found to be temperature, 180℃; time, 7 min, and pressure, 35 bar in compression molding. The optimised level of parameters has shown good response to the predicted model.
