The present invention provides a method of reusing prepreg material. The method comprises providing a remnant prepreg, defining a pattern of cutting the remnant prepreg framework to form a continuous strip of the remnant prepreg framework, and cutting the remnant prepreg framework to form a continuous strip of the remnant prepreg framework. The remnant prepreg framework continuous strip may be extruded into a short fibre molding compound (SMC). The SMC may then be used to make parts with lower structural requirements than the parts cut out of the prepreg broadgood. Such SMC parts may be used in industries such as aerospace; automotive; other transportation such as trucks, buses, and motorcycles; sporting goods; and wind.
摘要:
Fibrous materials, compositions that include fibrous materials, and uses of the fibrous materials and compositions are disclosed. For example, the fibrous materials can be operated on by a microorganism to produce ethanol or a by-product, such as a protein or lignin. In particular, a method of densifying a fibrous composition is disclosed, the method comprising: shearing a fiber source to provide a fibrous material; combining the fibrous material with a microorganism and/or enzyme to provide a fibrous material composition; encapsulating the composition in a substantially gas impermeable material; and removing entrapped gas from the encapsulated composition to densify the composition.
摘要:
A method for making substantially parallelepiped square cross-section formwork modules for building constructions, cut-off walls, embankments, dams, anti-erosion and anti-seismic foundations and/or the like, starting from used pneumatic tires, having at least the steps of: a) providing a used pneumatic tire deriving both from a periodic replacement of worn tires or from the rubber industry wastes or from the recovering of used pneumatic tires; b) removing from the pneumatic tire the two wall iron beads; c) performing cuts at diametrically opposite positions on the edges, wherein the cuts define cut-out regions separated by a middle solid region of the tire wall; d) removably mounting the pneumatic tire on basket-drum supporting means; and e) pressing in diametrical directions towards a center of the pneumatic tire the pneumatic tire tread portions near the cuts thereby causing the tire to assume a substantially parallelepiped configuration.
摘要:
The invention relates to a method of making a composite, the method comprising combining a fibrous cellulosic material with a radiation cross-linkable resin to provide a fibrous cellulosic material/cross-linkable resin combination, wherein the fibrous cellulosic material has an average length-to-diameter ratio of greater than 5, and wherein a standard deviation of a fiber length is less than eighty five percent of an average fiber length, and irradiating the fibrous cellulosic material/cross-linkable resin combination with from about 1 Mrad to 6 Mrad of electron beam irradiation.
摘要:
The present invention relates to a machine for manufacturing solid recovered fuel, to a process for obtaining solid recovered fuel and to the solid recovered fuel obtained from said process. The homogenization extruder machine comprises a main body (7) provided with a feed opening (6), an extruder screw (9) and an outlet (14), characterized in that it comprises a compression cone (11) arranged at the final end of the extruder screw (9) and opening and closing means (12) for opening and closing the outlet (14).
