Abstract: A composite structure is provided. The structure is based upon a three-dimensional woven fabric structure. The three-dimensional woven fabric has a first fabric layer and a second fabric layer spaced apart from the first fabric layer, with the layers connected by threads which form a portion of the three-dimensional woven fabric structure. The threads define voids in the space between the first and second layers. A first resinous material is coated onto and allowed to penetrate the first layer of the woven fabric structure. Next a second resinous material is coated onto and allowed to penetrate the second layer of the woven fabric structure. The voids are filled with a third resinous material. In order to complete the formation of the composite structure, the resins are fully cured. Using this method it is possible for the resinous materials to be chemically incompatible, yet mechanically attached by the cloth material.

Abstract: The polytetrafluoroethylene (PTFE) porous film of the invention is characterized in that the film is formed from a PTFE resin molding powder obtained by suspension polymerization and has a porosity of 40 to 80%, and removal ratio of uniform particle having a 0.2 .mu.m diameter of less than 99% or bubble point of not less than 3 kg/cm.sup.2. This PTFE porous film is obtained by a process of compression-molding a PTFE resin molding powder to prepare a preform, sintering the preform at a temperature not lower than its melting point, processing the preform into films, then laminating at least two of the obtained films, fusing the films to unite them, and subjecting the obtained film to uniaxial or biaxial stretching at a temperature not higher than the melting point of PTFE. If desired, the finally obtained film may be subjected to heat setting. In the PTFE porous film of the invention, pores are nearly round and the diameters of the pores are almost uniform.
