    • Disclosed is a method for producing a three-dimensional composite structure and a method for producing the mold for the three-dimensional composite structure. The mold is formed of at least one rigid die member and a second thermoplastic die member. The second thermoplastic die member is formed by coupling a rubber flexible pattern to a surface of the first die member. Vacuum or pressure is applied to a heated thermoplastic sheet to cause the heated thermoplastic sheet to deform about the flexible pattern, thereby forming the second die. Strips of reinforced polymer thermoset pre-preg material are then positioned within the cavities formed by the flexible pattern and are allowed to cure. Optionally, heat, pressure, and vacuum may be applied to the mold construction to facilitate the curing of the thermoset materials.
    • 公开了三维复合结构体的制造方法和三维复合结构体的制造方法。 模具由至少一个刚性模具构件和第二热塑性模具构件形成。 第二热塑性模具构件通过将橡胶柔性图案耦合到第一模具构件的表面而形成。 将真空或压力施加到加热的热塑性片材上,使得加热的热塑性片材围绕柔性图案变形,从而形成第二模具。 然后将增强的聚合物热固性预浸料材料条定位在由柔性图案形成的空腔内,并使其固化。 任选地,可以将热,压力和真空施加到模具结构以便于热固性材料的固化。
