The centerline of an ultrasonic horn with a one half inch wide beveled tip was oriented at an angle of approximately 30 degrees to the mandrel surface, energized to vibrate at a frequency of 40mHz, and brought to bear on the tape in multiple parallel passes to cover and debulk the entire surface. Passes of the horn were made in the direction of the fiber tows at a rate of approximately one inch per second. The horn was set at a booster factor of 1: 1,80% amplitude. Next, another six inch wide, six inch long carbon fiber prepreg tape with unidirectional fibers located 90 degrees from the orientation of the first ply was laid on the first ply to form the second ply in the stack of plies. The ultrasonic horn was again brought to bear at an angle on the tape and moved over the second ply in the direction of the fiber tows to at least partially consolidate the first ply to the second ply and to debulk the lay-up consisting of the two plies. The ultrasonic horn is disposed as shown in Fig. 1. The energy level applied by the angled horn to the prepreg material was sufficient to reduce the viscosity of the thermosetting resin in each piece of tape of the two plies for at least partial consolidation and debulking but not high enough to cause full chemical cross linking of the resin which would inhibit the ability to lay-up another ply and eventually chemically cross link the resin in that ply to the resin in lower plies in the stack. A roller was configured to closely follow the horn to assist in the debulking process as shown in Fig. 2; page 12, paragraphs 2-4 * [A] 17 [Y] 7 [I] 3,8,13; | [A]WO2006042251 (BELL HELICOPTER TEXTRON INC [US], et al) [A] 1* figure 1 *; | [XY]US2014033653 (CHAM PAK MENG [US], et al) [X] 1 * figure 9; claim 7 * [Y] 7; | [X]EP3045489 (MITSUBISHI RAYON CO [JP]) [X] 1 * paragraph [0073] *; | [X]WO2018088173 (IHI CORP [JP]) [X] 1 * paragraphs [0043] , [0047]; figures 5,6 * | by applicant | WO2013007263 |
