    Abstract: A method for forming a multi-layered structure includes forming a resin-infused fibrous material (70) by applying a liquid resin component (60) onto the fibrous material (32) being pulled through an injection box (110) such that the fibrous material is partially impregnated and surrounded by the liquid resin component to form a resin-infused fibrous material. The resin-infused fibrous material is then introduced to a first die (130) and partially cured to form a partially-cured fiber-reinforced core material (80). The core material exits the first die to an intermediate region, where a polymer layer (40) is then applied onto at least a portion of the outer profile surface of the core material. The material then enters a second die (140), where the liquid resin component is fully cured to form a fiber-reinforced thermoset core material (30) having the polymer layer adhered thereon within the second die, thus forming the multi-layered structure (20).

    Abstract: A process of modifying a surface of a composite material base unit includes: providing the composite material base unit; pressing at least one impression module of a modifying unit on the surface of the composite material base unit to form at least one surface geometry on the surface; optionally heating the surface of the composite material base unit by at least one or more of heating before pressing, during pressing, after pressing, or combinations thereof; the composite material base unit contains at least one or more of a resilient material, a covering material, or a combination thereof, the at least one impression module includes at least one protrusion, and/or at least one depression resulting in the surface geometry on the surface. Also herein is a process for preparing an interlocked composite material base unit and a process of utilizing the composite material base unit in automotive and construction.
