Abstract

533,369. Plywood. JABLONSKY, B. Aug. 11, 1939, No. 23241. [Class 145 (ii)] A laminated material for use on aircraft &c. comprises laminae of wood, one or more of the laminae being perforated and the perforations being arranged so that the material as a whole is imperforate. The material may be formed of plywood which has been compressed to increase its density. The outer lamina may have an indented surface formed by placing reticulated material against the surface during the compression process. A fabric layer may be included as a reinforcement. Specifications 493,145, [Group XXXIII], 502,826 and 519,061 are referred to.
