Abstract: A preform moulding material includes two individual unidirectional reinforcement layers of a fibrous reinforcement material and a resin material between adjacent ones of the fibrous reinforcement layers. The resin material is a matrix resin material that partially impregnates and conjoins the fibrous reinforcement layers. Each of the fibrous reinforcement layers includes a fabric that is skewed relative to a lengthwise direction of the preform moulding material and includes a weft of unidirectional fibrous reinforcement material disposed at an angle relative to the lengthwise direction and a warp of fibres in the lengthwise direction. The orientation of the unidirectional fibrous reinforcement material of one of the reinforcement layers differs from the orientation of the unidirectional fibrous reinforcement material of the other reinforcement layer such that the preform moulding material is bi-axial prepreg.

Abstract: An apparatus for manufacturing a multi-layered preform molding material includes a reinforcement material and a resin material. The apparatus includes a mechanism for joining the reinforcement layers together by impregnation of the resin material into the reinforcement material to form the molding material, thereby obviating the need for any additional bonding to join the individual reinforcement layers before impregnation.
