Foundation Elements for Naval Low-Rise Buildings

Abstract

Natural fiber composites are commonly used in residential decking, siding, and fencing applications, but their use in high-load structural applications has been limited by their low strength performance. However, wood-plastic composites (WPCs) consisting of nylon 12 and thermoplastic epoxy resin (TPER) exhibit excellent mechanical performance. This study evaluated the extrusion parameters for each composite including: barrel/die temperature profile, lubricant compatibility, wood flour (WF) content, and WF moisture content (MC). Increases in strength and modulus of both composites indicated significant adhesion between polymer and wood components. These composites show promise for use in structural applications currently lacking WPC presence.
