Flexural properties and shock‐absorbing capabilities of new face guard materials reinforced with fiberglass cloth

Abstract

The flexural strength (74.6 MPa) and flexural modulus (6.3 GPa) of the experimental material with four sheets were significantly greater than those of the 3.2-mm commercial specimens, except for the flexural strength of one product. The first peak intensity (515 N) and maximum stress (2.2 MPa) of the experimental material with four sheets were significantly lower than those of the commercial 3.2-mm specimens, except for one product for each property. These results suggest that the thickness and weight of the FG can be reduced using the experimental fiber-reinforced material.

Combined analysis of shock absorption capability and force dispersion effect of mouthguard materials with different impact objects

“…The reliability and superiority of such a combined measurement system was already well documented in previous studies 29,30) . Low pressure two-sheet type (LW) and medium pressure mono-sheet type (MS) Prescale films were used to measure peak stress levels ranging from 2.5 to 10 MPa and 10 to 50 MPa respectively.…”

Improvement of the Shock Absorption Ability of a Face Guard by Incorporating a Glass-Fiber-Reinforced Thermoplastic and Buffering Space

“…The homemade glass-fiber-reinforced thermoplastic materials were prepared using a previously reported method [24]. Using AP16 and sheets of plain-woven E-glass fiber cloth (M100X104H, Unitika, Osaka, Japan, with a density of 100 g·m −2 ), a vacuum hot press method was used to create GF containing four sheets of glass fiber cloth with two sheets on each outer surface [24].…”

“…Using AP16 and sheets of plain-woven E-glass fiber cloth (M100X104H, Unitika, Osaka, Japan, with a density of 100 g·m −2 ), a vacuum hot press method was used to create GF containing four sheets of glass fiber cloth with two sheets on each outer surface [24]. The AP16 and the sheets of fiberglass cloth were separately shaped into squares with a side length of 110 mm using an ultrasonic cutter (Labo Sonic Cutter model NE87; Nakanishi Inc., Tochigi, Japan).…”

“…To solve this problem, Abe et al attempted to reduce the thickness of the conventional hard thermoplastic by reinforcing it with fiberglass [24, 25]. The composite material is widely known as fiber-reinforced thermoplastic (FRTP).…”

Effect of dsDNA wrapped single-walled carbon nanotubes on the thermal and mechanical properties of polycaprolactone and polyglycolide fiber blend composites

“…During bend testing, samples did not break due to the elastic characteristic of the thermoplastic biomaterials making up the samples, which cause them to continue to bend rather than break. However, it is common practice for characterization of thermoplastics to use the maximum value attained during bend testing as the bending strength [43]. The test was stopped when the machine started to compress rather than bend the biopolymer samples.…”
