Abstract
The polyester fiber was utilized to fabricate the woven spacer fabric on the common loom, and the sandwich panels were produced by resin transfer molding process (RTM). The parameter of RTM molding process was determined. The correct ratio of resin, curing agent and accelerator in RTM process is 100:86:1. The injection temperature is 65°C. Injection time is shorter than 2 hours. Flexure and flatwise compression of composite panels were tested. The experiment result shows: flexure property and flatwise compression property of the RTM composite panels are better than that produced by handle paste shaping process.
