A non-penetrating multi-layer continuous hose and a preparation method thereof are provided. The hose includes an outer coating, a reinforcement layer, and an inner coating. The inner coating and the outer coating can have one or more layers with different materials and have an adjustable thickness. The hose is prepared by simultaneously performing extrusion coating inside and outside the reinforcement layer rather than penetrating the fiber reinforcement layer. The hose exhibits improved layer-to-layer adhesion and has high strength, and continuous production can be achieved to meet the length requirement in various kinds of construction, which has high applicability.

A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.

Open cell foam compositions are provided including a thermoplastic polymeric matrix and at least one filler. In some embodiments of the foam compositions, the filler includes nepheline syenite. Methods of making the foam compositions are described, the methods including (a) obtaining a composite materials containing a first thermoplastic polymer having a filler component and a blowing agent distributed therein; (b) coextruding the composite material with a second thermoplastic polymer and a third thermoplastic polymer to form a three-layer composition, wherein the three-layer composition includes a middle layer comprising an open cell foam formed from the foam composition, and the middle layer is disposed between the first and the second outer layers formed from the second and the third thermoplastic polymers, respectively; and (c) separating the middle layer from each of the first and the second outer layer. The first thermoplastic polymer is different from the second and the third thermoplastic polymers.

Systems and processes that integrate thermoplastic and shape memory alloy materials to form an adaptive composite structure capable of changing its shape. For example, the adaptive composite structure may be designed to serve as a multifunctional adaptive wing flight control surface. Other applications for such adaptive composite structures include in variable area fan nozzles, winglets, fairings, elevators, rudders, or other aircraft components having an aerodynamic surface whose shape is preferably controllable. The material systems can be integrated by means of overbraiding (interwoven) with tows of both thermoplastic and shape memory alloy materials or separate layers of each material can be consolidated (e.g., using induction heating) to make a flight control surface that does not require separate actuation.
