A method of recovering filler material from a polymer material comprises (a) heating the polymer material to a first temperature; (b) heating the polymer material to a second temperature higher than the first temperature resulting in a pyrolyzed material; (c) elutriating the pyrolyzed material to obtain a separated mixture; and (d) filtering the separated mixture to obtain the filler material.

A method for rapidly fabricating or repairing a fiber reinforced composite may include the use of a covalent adaptable network polymer (CAN) powder for encapsulating reinforcing fibers or welding to a CAN matrix. The fiber reinforced composite may be formed or repaired by applying CAN powder to reinforcing fibers or to a damaged area of a fiber reinforcing composite and compressing the CAN powder with the reinforcing fibers or the damaged area of the fiber reinforced composite at a relatively low temperature, temperature and processing time to form a CAN matrix. The method may be configured for fabricating a fiber reinforced composite having specific desired material properties by varying the arrangement and materials used.

The present invention provides a method for manufacturing a cushion body with a concave-convex structure and a mold for manufacturing the cushion body with the concave-convex structure. A first elastic sheet is pasted on a second elastic sheet. The first elastic sheet is a closed-hole elastic material. The second elastic sheet is an opened-hole elastic material. The first elastic sheet and the second elastic sheets are combined and heated. Finally, the first elastic sheet and the second elastic sheet that are heated are sucked using the mold under a negative pressure from one side of the second elastic sheet and cooled at the same time, so that the first elastic sheet and the second elastic sheet can be deformed using the concave-convex structure of the mold and cooled to be shaped, thereby obtaining the cushion body with the concave-convex structure.

The invention relates to an injection molded part comprising a composition comprising: a. Polyarylene sulfide (PAS) in an amount of between 50 wt % and 90 wt %; b. Glass fibers in an amount of between 10 wt % and 50 wt %; wherein the composition has a sodium content of at most 3500 ppm as measured by Inductively coupled plasma atomic emission spectroscopy (ICP-AES) and wherein the composition has a iodine content of at most 100 ppm as measured by X-ray fluorescence (XRF) and wherein the weight percentage and ppm is with respect to the total weight of the composition. The invention further relates to a fuel cell comprising the injection molded part.

One or more reactants are flowed into thermal contact with a heating element in a reactor for a first time period. During a first part of a heating cycle, the one or more reactants are provided with a first temperature by heating with the heating element, such that one or more thermochemical reactions is initiated. The one or more thermochemical reactions includes pyrolysis, thermolysis, synthesis, hydrogenation, dehydrogenation, hydrogenolysis, or any combination thereof. The first heating element operates by Joule heating and has a porous construction that allows gas to flow therethrough. During a second part of the heating cycle, the one or more reactants are provided with a second temperature less than the first temperature, for example, by de-energizing the heating element. A duration of the first time period is equal to or greater than a duration of the heating cycle, which is less than five seconds.
