摘要：
A process for manufacturing a composite structure, comprising:
providing a plurality of first mandrels (200), each of the first mandrels comprising a base (202) and a plurality of projections (204;204A;204B) arranged longitudinally along and projecting vertically out from the base (202);
providing a plurality of second mandrels (238);
providing a plurality of first ribbon plies (276;276A), each of the first ribbon plies (276;276A) comprising a sheet of fibrous material;
arranging each of the first ribbon plies (276;276A) with a respective one of the first mandrels (200), the arranging of each of the first ribbon plies (276;276A) comprising substantially covering each surface (222;224;226) of each of the projections (204;204A;204B) of one of the first mandrels (200) with a respective one of the first ribbon plies (276;276A);
mating each of the second mandrels (238) with a respective one of the first mandrels (200) such that each of the first ribbon plies (276;276A) is sandwiched between a respective one of the first mandrels (200) and a respective one of the second mandrels (238); and
curing resin disposed with the first ribbon plies (276;276A) to consolidate the first ribbon plies (276;276A) together and form a fiber-reinforced composite core structure of an acoustic panel (332).
