A method of manufacturing a composite product includes recovering a wet composite waste from at least one of the manufacturing process or an end-of-life product. The wet composite waste includes a first resin and a plurality of first fibers that are bound together with the first resin. The method also includes grinding the wet composite waste after recovering the wet composite waste. The method also includes mixing the wet composite waste with the second resin into a homogeneous mixture and placing the homogeneous mixture into a cavity. The method includes curing the second resin of the homogeneous mixture such that the homogenous mixture hardens to form a composite product that includes the first resin, the second resin, and the plurality of first fibers.

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.

Herein is described a carbon fiber and glass fiber hybrid fabric having a total areal weight of less than about 500 g/m.sup.2.

A nonwoven mat and a method of making a nonwoven mat are provided. The nonwoven mat includes reinforcing fibers and a binder composition that includes a polycarboxy polymer and polymer microspheres. The binder composition may also include low-density fibers, such as microfibrillated cellulose fibers. The polymer microspheres have a thermoplastic shell that encapsulates a blowing agent. The thermoplastic shell has magnesium hydroxide on its outer surface. The components of the binder composition interact with one another and/or the reinforcing fibers to form a nonwoven mat having a less permeable structure and a higher caliper.
