Preparation and optimization of aerogel flyer-plates with graded density

Resorcinol formaldehyde (RF)/carbonized resorcinol formaldehyde (CRF) aerogel flyer-plates with graded density were fabricated via simple and optimized methods. The preparation of multilayer aerogel was studied, and any extra glue was used in the preparation which included sol-gel techniques and supercritical drying. The problem of dense layer and the shrinkage effect of aerogel was studied and well controlled. The aerogel flyer-plate with graded density was accelerated by laser beam, and impacted Al target with extending the rising edge of ramp compression by 50% in comparison to the contrast. It reflected the advantage of graded density structure in the laser driven compression experiment.157
