Compared with molding, winding and other molding technologies, carbon fiber pultrusion molding in the process operation doesn't require the use of sheet fiber materials or prepreg intermediate materials for cumbersome cutting and processing.

    Reinforcing fibers and matrix resin can be directly composite continuous production, production process fiber continuity degree is very high, can effectively avoid the emergence of waste.

    Carbon fiber pultrusion molding process can be based on the application requirements of composite products with different types of reinforcing fibers and matrix resin type selection and matching, can achieve different mechanical strength, stiffness, toughness and thermal properties of the reasonable design and effective realization.

    Carbon fiber pultrusion molding technology can be based on the product's appearance requirements for the shape of the heterogeneous cross-sectional shape of the unlimited design, so whether it is the fine structure or appearance of the structure, pultrusion process have reached a strong degree of flexibility in the design of space.

    Carbon fiber pultrusion molding process can be automated or semi-automated streamlined operations, the composite material "molding" and "curing" of the two operating processes for the merger of continuous processing.

    Currently using pultrusion molding of composite products production speed can reach 10m/min, high production efficiency, which is also molding, laminating, vacuum infusion molding and other composite molding technology can not be achieved.

    In the field of engineering processing of composite products suitable for the production of profiles and winding molding process and weaving molding process, which due the limitations of the principle of work, the above two composite molding process can only produce a single cavity of the simple cross-sectional shape of the profiled material, and for the axial reinforcing fibers of the layup and arrangement of the more difficult, so that the improvement of the mechanical properties of composite materials of a particular direction of the process factors are more limited.

    Oleh itu, the process factors for improving the mechanical properties of composites in specific directions are more limited. Carbon fiber pultrusion molding technology has higher flexibility in product structure design, and can realize the production of variable cross-section profiles in the process of continuous production at the same time.

    Carbon fiber pultrusion molding process has a high degree of automation, in the continuous production process, the composite material profile can be accurately controlled by a number of process parameters, such as traction driving force, axial preload, winding and weaving with the preload, the gradient distribution of heating temperature of the pultrusion mold, the flow rate of the resin liquid injection and the hauling speed, so that it can greatly ensure that the quality of the profile in the axial direction and the structure of the stability and uniformity of the profile.

    The precise design of the parameters also realizes the designability and controllability of the structure.

    As the curing process of composite profiles is carried out within the envelope of the profile molding, the overall size of the profile after curing has a high degree of refinement and stability, and the resulting product has a high surface finish, making it easy for secondary processing and use.
