Methods of making a composite aircraft primary structure include selecting a compression moldable composite sheet molding compound; preparing a first and a second layup with the compression moldable composite sheet molding compound to form a first and a second 3D preform; and compression molding the first and the second 3D preforms to form a first and a second component part. Further, the first component part comprises first geometric joint features, the second component part comprises second geometric joint features, and the second geometric joint features are complementary to the first geometric joint features such that the second geometric joint features are configured to mate with the first geometric joint features. The method further includes assembling the aircraft primary structure by joining the first component part with the second component part by aligning and mating the first geometric joint features and the second geometric joint features; and securing the same.
