Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

An apparatus includes a first thermoset layer that includes a first fibrous material embedded in a first thermoset matrix. The apparatus also includes a second thermoset layer that includes a second fibrous material embedded in a second thermoset matrix. The second thermoset layer is coupled to the first thermoset layer to form a joint. Further, a gap is defined between the first thermoset layer and the second thermoset layer. The apparatus also includes a thermoplastic filler that is made from a thermoplastic material. The thermoplastic filler is positioned within the gap.

There is provided a method for manufacturing a joint member obtained by joining a carbon fiber composite material containing a thermoplastic resin as a matrix and a metal. The method includes a step (i) of forming an uneven shape having a depth of 0.02 to 0.6 mm on a surface of the metal at a joining portion; a step (ii) of providing a thermoplastic resin layer having a thickness in the range of 5μm or more and 5 mm or less at a joining portion between the surface of the metal and a surface of the composite material; and a step (iii) of melting the thermoplastic resin layer by heating the joining portion to thereby combine the metal and the composite material into one.

A method for assembling a skin and a flange of a stiffener. The periphery of the contact between the skin and the flange of the stiffener is sealed by applying a bead of adhesive on the flange of the stiffener in contact with the skin. A first and second orifices are made in the skin. The orifices open at the interface between the skin and the flange of the stiffener. The adhesive is injected through the first orifice at the interface between the skin and the flange of the stiffener while keeping the skin in contact with the stiffener until the interface between the skin and the stiffener is completely filled with the adhesive.

Embodiments of reinforced composite structures for aircrafts and methods for making such reinforced composite structures are provided herein. A reinforced composite structure for an aircraft comprises a fiber reinforced composite stringer. The fiber reinforced composite stringer comprises a beam body portion and a runout portion that extends from the beam body portion in a first direction. The beam body and runout portions are defined by projection of a variable I-shaped cross-section in the first direction along at least a portion of an entire combined length of the beam body and runout portions. The variable I-shaped cross-section has a cap section, a foot section, and a web section that extends between the cap and foot sections. The variable I-shaped cross-section is configured such that a height of the web section tapers in the first direction along at least a portion of an entire length of the runout portion.
