A method for joining a ceramic matrix composite (CMC) component includes placing a plurality of joining plies onto a specified area such that a respective fiber direction of each of the plurality of joining plies is off-plane to a fiber direction of one or more composite plies of the specified area. The respective fiber direction of each of the plurality of joining plies differs from the respective fiber direction of each adjacent one of the plurality of joining plies.

The disclosed technology includes a bioabsorbable material configured to be delivered to tissue. The material includes a shape-memory polymer compressible in a delivery configuration and configured to swell within a predetermined period of time. The shape-memory polymer includes one or more functional groups for reversible bonding between adjacent functional groups to transition between an approximately linear polymer and an approximately non-linear polymer upon exposure to a stimulation.

A three-phase composite, and a preparation method and use thereof are provided. The three-phase composite includes a hollow glass microsphere composite foam and a plurality of carbon fiber tubes filled in the hollow glass microsphere composite foam; where the carbon fiber tubes are arranged in a two-dimensional closest packing manner, two adjacent carbon fiber tubes have a center-to-center spacing of 29.9 mm to 34 mm, and each of the carbon fiber tubes has a wall thickness of 0.45 mm to 1 mm; and two ends of each of the carbon fiber tubes each are sealed by an end cap.

A high-frequency dielectric heating adhesive sheet includes an adhesive layer. The adhesive layer contains a thermoplastic resin having a reactive site, a dielectric filler that generates heat upon application of a high-frequency electric field, and a silane coupling agent.

A heater for a cigarette-like electronic cigarette and a method of manufacturing the heater are provided. The heater is provided with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin.
