Abstract: A composite panel holder having a plurality of layers, wherein each layer is a fiber matrix tape including a plurality of fibers immobilized in a matrix of a thermoplastic or thermoset polymer, and each layer is oriented at a different angle but in a same plane relative to a layer it is in direct contact with; and wherein the composite panel holder comprises six portions oriented in different directions, as viewed along a longitudinal axis of the panel holder. A method of preparing the composite panel holder that includes impregnating a plurality of fibers in a thermoplastic or thermoset polymer to form a matrix of fibers in the polymer, forming the matrix into a plurality of unidirectional tapes, stacking the tapes to form a composite structural panel with each of the tapes oriented in a different direction from adjacent tapes; and pressing the structural panel with a thermoforming press.

Abstract: A thermoplastic composite suitable for induction welding including a polymer laminate including two or more plies, wherein the polymer is selected from polyaryletherketone (PAEK) polymers such as polyetherketone (PEK), polyether ether ketone (PEEK), polyetherketoneketone (PEKK), polyetheretherketoneketone (PEEKK), and polyetherketoneetherketoneketone (PEKEKK), or preferably, the polymer laminate comprises polyetherketoneketone (PEKK), and one or more layers of a continuous carbon nanomaterial based susceptor between each pair of the plies. Methods for making the thermoplastic composite are also described.

Abstract: A multi-layer composite has at least one elastomer layer and at least one barrier layer. In various embodiments, the composite contains at least two elastomer layers alternating with at least two barrier layers. In other embodiments, the composite comprises at least ten alternating barrier and elastomer layers. The barrier layer is made of an amorphous polymer, and is provided in the form of a film. Preferably, the amorphous polymer film has a gas transmittance rate (GTR) of less than 40 cc·mil/m2·day·atm; preferably less than 20 cc·mil/m2·day·atm; measured as nitrogen transmittance at 0% relative humidity at 23° C.
