Methods and apparatus to couple a decorative layer to a panel via a high-bond adhesive layer are disclosed. An example apparatus includes a panel, a high-bond adhesive layer fixed to the panel, a liner fixed to the high-bond adhesive layer that is fixed to the panel, and a first decorative layer removably coupled to the liner that is fixed to the high-bond adhesive layer via a second adhesive layer. The high-bond adhesive layer is to impede at least one of gas or vapor from escaping the panel to deter the at least one of gas or vapor from exerting a pressure on the first decorative layer to deter a portion of the first decorative layer from separating from the panel.

Methods and apparatus to form venting channels on a panel for a decorative layer are disclosed. An example method includes contacting an outer surface of a tool to an outer resin layer of a panel. The outer surface of the tool has protrusions. The example method includes moving the outer surface of the tool on the outer resin layer of the panel in a first direction to cause the protrusions of the tool to form first venting channels on the outer resin layer of the panel and coupling a decorative layer to the outer resin layer of the panel via an adhesive layer. The first venting channels are to vent at least one of gas or vapor away from the decorative layer to deter separation of a portion of the decorative layer from the outer resin layer.

Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

A method of constructing a composite, radius filler noodle for a co-cured spar or stringer used in aircraft construction includes forming a core of the noodle from unidirectional pre-preg tape and stacking pluralities of pre-prep fabric strips in layers surrounding the core.

A honeycomb structural body includes multiple cores, at least face sheet, and at least one reinforcement sheet. The multiple cores each have a honeycomb structure, and are bonded to each other with foamed adhesive in a direction in which the number of multiple pores formed by the honeycomb structure increases. The at least one face sheet is adhered to the multiple cores so as to cover the multiple pores. The reinforcement sheet is placed between the multiple cores and the at least one face sheet, at a position where the reinforcement sheet covers the foamed adhesive.

A process for forming defect-free fibrous composite materials. More particularly, a process for forming blister-free fibrous composites without having to actively monitor or control blister formation during molding of a stack of plies, and to blister-free composite materials fabricated therefrom. Fibrous plies are coated with a dry, particulate binder without impregnating the plies with the binder. Gaps between fibers/tapes allow air to diffuse out of the stack without affecting the binder coating, thereby avoiding blister formation.

A high-CTI and halogen-free epoxy resin composition for copper-clad plates and uses thereof is provided. The formula of the high-CTI and halogen-free epoxy resin composition for copper-clad plates comprises 100˜140 parts of halogen-free phosphorous epoxy resin, 10˜35 parts of dicyclopentadiene phenolic epoxy resin, 32˜60 parts of benzoxazine, 1˜5 parts of phenolic resin, 0.05˜0.5 parts of accelerants; and 25˜70 parts of fillers, by weight.

The manufacturing method object of the invention comprises the following stages: A) stacking strips of prepreg material on a laminating tool (14), so that an angled laminated part (2) is obtained comprising a central section (2a) contained in a first plane (12), at least one side section (2b) contained in a second plane (13), and at least one bending axis (5) between the central section (2a) and the at least one side section (2b), so that, the first plane and the second plane form an angle α; B) forming of the angled laminated part (2) comprising bending along the bending axis (5) the, at least, one side section with respect to the central section (2a), obtaining a formed part (6); C) curing, of the formed part (6).

A method for manufacturing a composite may include: selecting an interlayer material having a first distortional-deformation capability; selecting a matrix material having a second distortional-deformation capability, which is less than the first distortional-deformation capability; disposing at least one reinforcing layer, formed of reinforcing fibers of a reinforcing material, and at least one interlayer, formed of a nonwoven fabric of the interlayer material, in an alternating configuration; and infusing the at least one reinforcing layer and the at least one interlayer with the matrix material such that the matrix material flows though the at least one reinforcing layer and the at least one interlayer. Selection of the interlayer material having the first distortional-deformation capability and the matrix material having the second distortional-deformation capability is configured to increase tensile strength of the composite.
