Embodiment Construction

[0032] The structural composites described herein are heterogeneous compositions that possess compressive strength and stiffness, enabling their use as wood substitutes in a wide variety of applications, including those where applicable building code requirements. Additionally, the structural composites of the present invention can replace other materials, such as aluminum, that have a higher modulus of strength than wood. The term heterogeneous means that at least some of its constituents are concentrated within the structural composite rather than uniformly dispersed. The present composite material can be engineered, meaning that its external shape and its components and their position and shape can be chosen to meet the strength and stiffness required for the particular task the composite material will be placed into. As a simple example, the present structural composite can be designed with stiffeners spaced from the neutral axis, similar to the flanges of an I-beam, provi...

Abstract

A structural polymeric composite includes a stiffening layer. The composite is made in a continuous extrusion process in which the stiffening layer is pulled through a cross-head die as a polymer is extruded over it. The layer includes a film or textile carrier, a filler of carbon fibers, fiberglass, organic fibers or minerals forming a mat. A binder may be dispersed over the mat and a second carrier applied. The mat is subjected to heat and pressure to soften the carriers and binder so they penetrate into the interstices of the filler and binds mechanically with them and the carriers and binder bind chemically with each other to form the stiffening layer. A polymer is then extruded over the stiffening layer, which may be used flat, provided with holes or punches for composite action withthe polymer, formed into a profile, or segmented to provide spaced-apart stiffening layers.

Description

technical field [0001] The present disclosure relates to polymeric composites. More specifically, the present disclosure relates to reinforced polymeric composites. Background technique [0002] Polymer materials have replaced wood in many applications requiring structural components such as posts, beams, decking, framing members, trim and railings. Window frames and shutters are made of hollow vinyl profiles. Upholstery moldings and most recent screen doors are made of foamed PVC. [0003] Plastic has advantages over wood, including lower cost and less maintenance, but it often does not have the inherent strength of wood without the addition of other materials such as wood or metal inserts as secondary reinforcements to add stiffness. Adding these types of secondary reinforcements increases material and labor costs and is complicated by the need for additional types of materials. [0004] Structural composite materials are known. For example, US 4910067 discloses a str...
