1. Способ изготовления детали из композиционного материала, имеющей тело, прикрепленное по меньшей мере к одной платформе, присутствующей на одном конце упомянутого тела, который содержит
использование многослойного переплетения между множеством слоев нитей основы для формирования волоконной болванки, имеющей продольное направление, соответствующее продольному направлению тела детали, которая должна быть изготовлена, причем эта волоконная болванка делится в направлении ее толщины на первую, вторую и третью части по меньшей мере в одной зоне несвязывания, смежной с одним из ее концов, причем первая часть располагается между второй и третьей частями, с которыми она соединена путем переплетения снаружи упомянутой по меньшей мере одной зоны несвязывания;
использование волоконной болванки для формирования заготовки для детали, которая должна быть изготовлена, путем складывания сегментов второй и третьей частей, которые не связаны с первой частью, на противоположных сторонах первой части, с помощью формирования сложенных сегментов второй и третьей частей так, чтобы сформировать части заготовки для платформы изготовляемой детали, а также складывания сегмента первой части для заполнения канавки, присутствующей в зазоре между второй и третьей частями; и
уплотнение этой заготовки с помощью матрицы для того, чтобы получить деталь, сделанную из композиционного материала, имеющую по меньшей мере одну интегрированную платформу.

3. Способ по п. 1, в котором первая, вторая и третья части вместе содержат больше слоев нити основы, чем количество слоев нити основы в остальной части волоконной болванки, расположенной снаружи упомянутой по меньшей мере одной зоны несвязывания.
4. Способ по п. 3, в котором один или более дополнительных слоев основы ткутся вместе со слоями нитей основы по меньшей мере второй и третьей частей.
5. Способ по п. 1, в котором первая, вторая и третья части вместе содержат меньше слоев нити основы, чем количество слоев нити основы в остальной части волоконной болванки, расположенной снаружи упомянутой по меньшей мере одной зоны несвязывания.
6. Способ по п. 5, в котором один или более слоев основы убираются во время переплетения по меньшей мере упомянутых второй и третьей частей.
7. Способ по п. 1, в котором деталь из композиционного материала соответствует авиационной детали, выбираемой из по меньшей мере одной из следующих деталей: лопатка турбинного двигателя, лопасть турбинного двигателя, профиль усиления и подвеска.
