Abstract: Methods for producing a flexible, fibrous ablator thermal protection material, for use in association with a space vehicle that passes through an atmosphere in which severe heating is experienced. A phenolic resin and/or a silicone resin can be used. The elastic modulus of the resulting material is low, in a preferred range of about 200-5000 kPa, and can be controlled by choice of a curing temperature and/or a time interval length for curing.

Abstract: Disclosed is an exchangeable and wearable keepsake containing a volume of breath from a loved one, comprising a sealed capsule having an inlet aperture and an outlet aperture for forcing air into the capsule and retainment thereof. A method of gift exchange and capturing a quantity of breath is further disclosed, wherein a user forces air into a capsule as the air within the capsule is displaced, trapping a quantity of breath within the capsule indefinitely. A non-return valve is positioned in the inlet aperture and an outlet vent is positioned at the outlet aperture to allow air to exit the capsule control volume as incoming air is forced thereinto. The device is adapted to provide a memento or gift that allows a user to carry an article providing physical remembrance of lost or loved ones. The enclosure itself comprises a hollow structure that can take several ornamental forms.
