Definitions

  • This invention relates to system for manufacturing natural fiber filled thermoplastic and thermoset composite materials and processes for their manufacture.
  • it relates to cellulose fiber filled compositions reinforced by injected ropes which have high strength, elastic modulus and density values inside the profile, and processes for their manufacture.
  • Composite materials are often optimized by selecting components for their strength, stiffness, flexibility, and durability. Current development is focused on improving material qualities ranging from strength to durability, as well as improving the compatibility of matrix components for longer lasting products and examining new manufacturing methods for ropes reinforced wood plastics composites.
  • Wood-plastic composites are a product class that has been developing over the last 40 years resulting in increased applications and expanded market share.
  • Thermoplastics are a class of polymers that can be heated and softened, cooled and hardened, high density polyethylene (HDPE), polypropylene (PP) and polyvinyl chloride (PVC) are the most common thermoplastic polymers used in WPC (Klyosov 2007) (1) .
  • Wood has many advantages to traditional fillers like lower cost, relatively high strength to weight ratio, low density, is relatively soft and easily integrated into existing plastic production lines.
  • Mesh sizes of particles used in WPCs will vary depending upon the desired product properties and finish and are most commonly from 10 to 80 meshes (Patterson 2001 ; Clemons 2002) (2) .
  • WPCs started being produced by the plastics industry which had prior expertise in processing and manufacturing of plastic products (Clemons 2002) i3 ) . This industry had used filler materials in the past and when wood became a viable option; it was integrated into their existing production lines. WPCs starting in a molten state can be formed into highly detailed, linear profiles using extrusion processes. In any thermoplastic composite, the components must first be blended together and then later formed into the desired product.
  • Mixing or compounding is the act of combining the wood and polymer components together. It is also important in this step to wet or encapsulate the wood particles with the polymer. Proper dispersion and wetting allow uniform and more effective load transfer to occur throughout the composite. If not compounded properly, the composite will have reduced mechanical properties compared with an optimally compounded blend and increases the risk of durability issues. After compounding, the material can go directly to shape formation of the final product or can be chipped into pellets for later use.
  • Extruders serve the two main purposes of compounding the wood and filler, and then forming the shape of the extruded profile.
  • the wood and polymer components are metered and fed into the extruder and mixed using single or twin-screw configurations.
  • the screws act to mix and move the material forward.
  • the mix is heated through friction between the barrel, screw, and wood-polymer mix as well as by heated zones along the length.
  • a die At the end of the extruder is a die through which the material is fed, forming the desired profile.
  • Twin screw extruders are sometimes used as compounding units for producing pre -blended pellets.
  • Composite materials are often optimized by selecting components for their strength, stiffness, flexibility, and durability. When compared with individual materials, composites may also offer more consistent performance, lower production costs, and create an avenue for the utilization of renewable resources.
  • WPCs are no different and are formulated to meet the needs of the consumer by finding the right balance of these properties. Mechanical properties and durability are among the most important to WPCs.
  • WPC decking making up the largest share of the WPC market (Clemons 2002) i4) , we can look at mechanical properties important to this market.
  • WPC deck boards are subjected to bending when they span a gap between supports and are being dynamically loaded when walked on and supporting the static loads (e.g. furniture and grills). For decking, this is important for limiting deflection of the product. It should be mentioned that a true elastic response in plastic composites is debatable, and the response of the material is highly dependent on the testing rate, temperature, previous history of the specimen, etc. WPC formulations and specimens from different testing facilities are difficult, but for research and development purposes determining these values as a comparison is helpful. WPCs have found success in a variety of markets including outdoor decking, railings, fences and landscaping timbers, but the number of applications for WPCs is limited to service requiring high -mechanical performance (Clemons 2002) (5) .
  • WPCs When compared with solid wood materials, Table 1, WPCs have lower mechanical properties in strength, stiffness, and creep resistance.
  • Elastic and strength properties are the primary criteria to select materials or to establish design or product specifications. Common applications include decking, railings, window profiles, roof tiles, and siding. These lumber products are generally manufactured using profile extrusion. Flexural and tensile properties of wood plastic composite (WPC) lumber generally fall between those of solid wood lumber. According to Table 1, most commercial wood plastic composites are considerably less stiff than solid wood (Clemons 2002) i6) .
  • thermoplastics-based wood filled composites WPC
  • head and die arrangements to feed ropes into extruded materials to increase flexural properties, impact resistance and tensile properties of extruded profile.
  • Fiber physical properties we can choose reinforcing material, predict how many ropes shall we use according to cross section of the profile and calculate the diameter of ropes for certain profile application. Using different materials with different rope’s diameter we can create materials with whatever mechanical properties we need. According to application of the profile we can choose reinforcing ropes (C) from Table 2 and Table 3 knowing that mechanical properties of polymer rope ⁇ hemp ⁇ steel wire ⁇ carbon nanotubes graphene rope.
  • Reinforcing ropes (C) are injected inside the profile through injectors (5) by extruder (11) together with long fibers and resins materials (B2) composition.
  • Other reinforcing materials are Composite and Textile Straps D materials:
  • Composite Strapping (D) is produced by a co-extrusion where polyester fibers are covered with plastic. Tensile strength of the strapping depends on the number and diameter of the fibers used.
  • Textile Strapping (D) is manufactured by hot-melt gluing polyester fibers together. Physical properties of the strapping are function of the number and the diameter of the fiber used.
  • Textile and Composite Straps are injected inside by extruder (11) together with (B2) composition and outside application by extruder (12) together with long fibers and resins materials (Bl) composition.
  • Reinforcing long fibers and resins materials (B) are extruded with extruder (11) as an intermediate filament formation (B2) and extruder (12) as an outside layer film (Bl) onto the profile (8).
  • Composite materials (B) contains plastic resins from 30% to 70% and long fibers up to 20 mm fiber elongation which content is from 70% to 30% respectively to plastic resins. Reinforced fibers are chosen from materials in Table 2.
  • Reinforcing ropes (C) (9) are forcibly extruded through injectors (5) by extruder (11) with (B2) materials which is surrounding the ropes inside the profile (8).
  • rope reinforced WPC profiles can be used as construction materials. They will replace wood beams and boards so trees will grow in factories. This application is done with adding (injecting) materials with strong Mechanical Properties to the recipe. And with calculating injected material for certain cross section beam, we can reach times better Mechanical Properties by making choice of added material from Table 2 and Table 3 and reach more and more the existing hardest wood beam properties.
  • New ropes reinforced composite profiles, beams, lumbers and deck boards will be resistant to bending according to injected rope material, radius of cross section and quantity.
  • Ultimate tensile stress (UTS) is the maximum stress that a material can be subjected to before breaking.
  • Modulus of elasticity (MOE) refers to a material’s ability to resist deformation and in a general sense is the stiffness of the material. Both the ultimate tensile stress (UTS) and modulus of elasticity (MOE) are increased properties in this case by adding reinforced materials like Polymer ⁇ Hemp ⁇ Steel wire ⁇ Graphene ropes. The number of applications for new rope RWPC is unlimited to service requiring high-mechanical performance of the extruded profile.
  • new rope RWPC When compared with solid wood materials, Table 1, new rope RWPC will have higher mechanical properties in strength, stiffness, and creep resistance by injecting reinforced materials like polymer ⁇ hemp ⁇ steel wire ⁇ graphene ropes. Elastic and strength properties of these materials are the primary criteria to select or to establish design or product specifications for common applications include decking, railings, window profiles, roof tiles, construction timbers and siding profiles. Flexural and tensile properties of new Rope Reinforced Wood Plastic Composites (RRWPC) lumber profile will be increased as much as used ropes number and cross-sectional area of used ropes are.
