Abstract: A multi-axial fibrous reinforcement material comprising at least one first layer comprising uni-directional fibre tows in a substantially 0 degree direction and at least one further layer comprising uni-directional fibre tows in a direction in a range substantially deviating from 0 degrees and from 90 degrees. The material further comprises a means for securing the layers in relation to one another, the securing means forming a venting structure to provide gas venting in a direction across the respective layers.

Abstract: Prepregs comprising fibrous reinforcing material and a heat curable resin are provided with a backing sheet whose surface has been treated to increase the surface tension which enhances the bonding between the prepreg and the backing sheet, and reduces resin removal when the backing sheet is removed. The use of the treated backing sheet also provides improved tack between prepregs when assembled in a stack for moulding after removal of the backing sheet.

Abstract translation: 提供了包含纤维增强材料和可热固化树脂的预浸料，其表面已经被处理以增加表面张力，从而增强了预浸料和背衬片之间的粘合，并且在去除背衬片时减少树脂去除。 经处理的背衬片材的使用还提供了改进的预浸料之间的粘合，当组装成堆叠以便在去除背衬片材之后进行模制。
