The nonwoven structure may comprise any of a variety of fibers. In certain embodiments, the composite may be substantially thermally insulating and/or acoustic insulating. Other aspects of the present invention are generally directed to systems and methods for making such composites, methods of use of such composites, kits comprising such composites, and the like.

Provided is a graphene foam laminate for use as a sealing material, comprising: (a) a layer of graphene foam having a thickness from 100 nm to 10 cm and comprising pores and pore walls having a 3D network of interconnected graphene planes or graphene sheets; and (b) a permeation-resistant polymer layer disposed on a primary surface of the graphene foam to form a two-layer laminate or two permeation-resistant polymer layers disposed on the two primary surfaces of the graphene foam to form a three-layer sandwich laminate, wherein the permeation-resistant polymer layer has a thickness from 10 nm to 1 cm.

Provided is a process for producing a graphene foam laminate for use as a sealing material, the process comprising (a) providing a layer of graphene foam; and (b) laminating the layer of graphene foam with one layer of permeation-resistant polymer to form a two-layer laminate or with two layers of permeation-resistant polymer to form a three-layer laminate wherein the graphene foam layer is sandwiched between the two permeation-resistant polymer layers. The two permeation-resistant polymer layers can be the same or different in composition. The product is a new, novel, unexpected, and patently distinct class of highly conducting, elastic, thermally stable, and strong sealing materials.

According to some embodiments, a fireproofing system for protecting an elongate member, comprising at least one inner layer configured to at least partially wrap around itself to form an inner passage, the at least one inner layer configured to generally resist heat, and an outer shell or member defining an interior opening, wherein the first layer is configured to be positioned within the interior opening of the outer shell or outer member, wherein an elongate member is configured to pass through the inner passage.

A panel and a method of making a panel are provided. The panel comprises a cured polymeric foam layer that is formed by application of a foam composition to an edge surface of the panel and then shaped and cured. The panel comprises man-made vitreous fibre or wood wool cement.
