  • Patent number: 9809702
    Abstract: Composites containing one or more synthetic plastics, such as thermoplastics, one or more natural materials, such as plant/tree fibers, and biochar and/or torrefied material are described herein. The composite can contain additional additives, such as reinforcing agents and/or fibers, compatibilizers, etc. The composites have improved mechanical and/or physical properties, such as strength, impact strength, rigidity/modulus, heat deflection temperature, moldability/melt flow index, renewability, and lower cost compared to composites that do not contain the biochar and/or torrefied material. The presence of the biochar and/or torrefied material also serves to remove the odor often associated with natural fibers and other additives.

  • Publication number: 20150361258
    Abstract: Super tough poly (lactic acid) (PLA)-based blends showing non break impact behavior have been developed. The blend contains a PLA resin, (b) a thermoplastic elastomeric block copolymer, and (c) a functionalized polyolefin copolymer. The blend is used as matrix to incorporate one or more additives, such as fillers (e.g., natural fibers and/or mineral fillers), nucleating agents, and/or chain extenders to form composites. In some embodiments, the blend is the continuous phase and the one or more additives are the dispersed phase. The composites exhibit improved impact strength and heat distortion temperature compared to neat or virgin PLA. For example, in some embodiments, the impact strength of the composite is from about 60 J/m to about 140 J/m and/or the HDT of the composite ranges from about 60 to about 115° C.

  • Publication number: 20050217156
    Abstract: A warning plate assembly for indicating the excess width of a tractor, in particular an agricultural tractor. The assembly comprises a holder having a fixing part (1) attached to the vehicle and a deployable arm (3) carrying the warning plate (9). The deployable arm (3) is swivellable about a vertical swivel axis (2a) of the fixing part between a lockable deployed position, in which the deployable arm and the warning plate are disposed transversely to the longitudinal direction of the vehicle, and a lockable retracted position in which the deployable arm is disposed substantially in the longitudinal direction of the vehicle. The length of the deployable arm (3) is adjustable (6,7) to cater for different widths of vehicle. The warning plate may be in two halves (10,11) hinged about a vertical axis so that the halves can be folded one over the over for storage.
