摘要： A method and apparatus for the additive manufacturing of three-dimensional objects are disclosed. Two or more materials are extruded simultaneously as a composite, with at least one material in liquid form and at least one material in a solid continuous strand completely encased within the liquid material. A means of curing the liquid material after extrusion hardens the composite. A part is constructed using a series of extruded composite paths. The strand material within the composite contains specific chemical, mechanical, or electrical characteristics that instill the object with enhanced capabilities not possible with only one material.

摘要： A method of improving the adhesion of metathesis compositions, such as ring-opening metathesis polymerization (ROMP) compositions, to a substrate is disclosed, in which an adhesion promoter is added to a polymerizable resin composition in order to improve the adhesion of the polymerizing resin to a substrate material. The addition of the adhesion promoter has been found to provide beneficial improvements in the adhesion of metathesis, especially ROMP, compositions to substrates, particularly glass surfaces, leading to improved characteristics in ROMP materials formed therefrom. The adhesion promoter generally comprises a functionalized silane compound and a peroxide compound. A ROMP composition is further disclosed comprising a cyclic olefin, a ROMP metathesis catalyst, and the adhesion promoter. Polymer products produced via metathesis (ROMP) reactions of the invention may be utilized to provide a wide range of materials and in a variety of composite applications. The invention has utility in the fields of catalysis, organic synthesis, and polymer and materials chemistry and manufacture.

The tape-shaped prepreg includes unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and has an arithmetic average roughness (Ra) of 0.1 to 10 μm in a direction perpendicular to the orientation direction of the reinforcing fibers, as measured according to JIS B 0601: 2013, and a warpage rate of 5% or less as determined by the procedure specified in (i) to (iii) below: (i) place a test piece of the above tape-shaped prepreg having a length of 100 mm in the fiber orientation direction on a plane in such manner that the end portions curl upward, (ii) measure the vertical distance from the highest position at the right end of the curled tape to the plane, which is denoted by a, and the vertical distance from the highest position at the left end to the plane, which is denoted by b, and calculate the arithmetic average of a and b, which is defined as the warpage distance, and (iii) calculate the warpage rate by the following equation: warpage rate (%)=warpage distance (mm)/100 (mm)×100.

摘要： According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

摘要： A laminate has stacked fiber-reinforced thermoplastic resin base materials that can be easily welded without affecting physical properties, and a welded article thereof. The laminate is obtained by stacking five or more layers of fiber-reinforced thermoplastic resin base materials, wherein the fiber-reinforced thermoplastic resin base materials are obtained by impregnating continuous reinforcing fibers having conductivity, which are aligned in parallel, with a thermos-plastic resin.

摘要： Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite materials which increases the positive buoyancy of the composites in water.

摘要： Methods of making fiber-containing prepregs are described. The methods may include the steps of providing a plurality of fibers, and applying a reactive resin composition to the plurality of fibers to make a mixture of the plurality of fibers and the resin composition. The reactive resin composition may include at least one of monomers and oligomers capable of polymerizing into a polymerized resin matrix. The mixture may be heated to a polymerization temperature where the monomers, oligomers, or both polymerize to form a fiber-resin amalgam that includes the polymerized resin matrix. The fiber-resin amalgam may be formed into the fiber-containing prepreg. Also described are methods of forming a fiber-reinforced composite that includes the prepreg.
