Spread-tow carbon fiber and resin form a lighter bipolar plate that cuts iron-related degradation while maintaining conductivity and low contact resistance.

A molded carrier between two louver shells adds rigidity while preserving surface appearance and reducing separate assembly steps.

Co-cured boxed thermoset composite stiffeners cut custom joining parts and manual bonding while preserving rigidity on complex forms.

Convex and concave FRP shaping preserves continuous fibers to raise rigidity and suppress deformation without honeycomb cores.

Continuous infrared heating, cooling, and cross-row forming rollers enable recyclable honeycomb plates with strong, homogeneous structure at high speed.

Overmolded stiffeners, sidewalls, and hinges create a welded monolithic control surface that cuts weight and improves impact resistance.

PVC with milled cereal chaff improves flexural strength and impact resistance while lowering water absorption and preserving a wood-like feel.

A self-heated vacuum mold forms and decorates an aircraft seat shell in one step, cutting finishing work, cost, and waste.

A vertically movable impregnation and guiding carriage enables continuous composite panel layup, cutting machine count, footprint, and production time.

Vacuum forming creates wavy thermoplastic honeycomb walls that improve compression resistance and reduce material usage.

This case integrates pultruded web supports with facesheets to reduce labor and complexity in sandwich panel manufacturing.

This case combines PVC with sized cereal chaff particles to improve outdoor extrudate strength, impact resistance, and water resistance.

A honeycomb core construction uses a gas-permeable connection layer bonded at web ends to join multiple cores.

Curved rollers separate wax honeycombs from moulding strips, eliminating iron powder contamination and reducing energy consumption.

Vacuum application during cooling seals cavities in cellulose-based composite cores, preventing trapped air from causing surface debossing defects.

Shaped protruding elements from extruded thermoplastic layers fuse to create a monolithic alveolar panel with uniform strength in both directions.

A twin-sheet thermoforming process sandwiches a micro-perforated closed cell polyolefin foam sheet between outer structural layers to create an air duct.

Segmented collar design on elongated bottle necks allows conventional equipment to grip and seat preforms accurately, preserving unoriented resin structure.

Molding bars create auxetic structures that absorb high-energy impacts while reducing weight penalties in aircraft.

Multi-stage heating of green honeycomb ceramic bodies at rates exceeding 80°C/hr reduces firing time while preventing cracking from thermal stress.

Flexible bag system applies atmospheric pressure to shape FRP structures with closed spaces.

Dynamic pneumatic pressure prevents overflow channel clogging and ensures reliable welding between inner and outer hoses.
