Abstract |
In order to study wearable air cushion materials capable of responding to
massive impact in high-altitude fall situation, high tenacity woven fabrics were bonded
by heat only depending on various type of thermoplastic films and then mechanical
properties were measured. Tensile strength, elongation, and 100% modulus
measurement results for 4 types of films show that TPU-2 has higher impact
resistance and easier expansion than PET-1. After thermal bonding, the combination
with the highest tensile strength was a material with a TPU-2 film for nylon and a
PET-2 film for PET, so there was a difference by type of fabric. The tear strength of
the bonded materials were increased compared to the fabric alone, which shows that
durability against damage such as tearing can be obtained through film adhesion. All
of the peel strengths exceeded the values r e quired by automobile airbags by about 5
times, and the TPU-2 bonded fabric showed the highest value. The air permeability
was 0 L/dm2/min. For both the film and the bonded material, which means tightness
between the fabric and the film through thermal bonding. It is expected to be applied
as a wearable air cushion material by achieving a level of mechanical properties
similar to or superior to that of automobile airbags through the method of bonding
film and fabric by thermal bonding. |
